　第１機械装置ＭＡの正常動作を表わす第１情報が制御装置４Ａから第１入力部２１に入力されると、第１信号表示灯２Ａの第１制御部２５Ａは、第１表示属性値を正常値に設定し、下表示部８１の光源９の発光色を緑色に設定する。このとき、第２表示属性値が初期値であれば、第１制御部２５Ａの制御によって、下表示部８１は緑色で連続点灯する表示状態Ａとなる。この状態で、作業者が例えばメンテナンス（異常発生を事前に回避するための予防的な保守作業）のために第１機械装置ＭＡにやってきて、メンテナンスの開始に先立って第１操作部３Ａを１回押し操作すると、第２情報が第２入力部２２に入力される。すると、第１制御部２５Ａは、第２表示属性値を、初期値から中間値に変更する。これにより、下表示部８１の表示状態は、緑点灯（表示状態Ａ）から緑色の点滅状態に変わり、表示状態Ｂとなる。表示状態Ｂを見た者は、正常状態にある第１機械装置ＭＡにおいて現在メンテナンスが行われていることを把握できる。 When the first information indicating the normal operation of the first mechanical device MA is input from the control device 4A to the first input unit 21, the first control unit 25A of the first signal indicator 2A sets the first display attribute value to normal. Value, and the emission color of the light source 9 of the lower display section 81 is set to green. At this time, if the second display attribute value is an initial value, under the control of the first control unit 25A, the lower display unit 81 enters the display state A in which the green display is continuously lit in green. In this state, the worker comes to the first mechanical device MA for, for example, maintenance (preventive maintenance work for avoiding occurrence of abnormality in advance), and operates the first operation unit 3A for 1 before starting the maintenance. When the push operation is performed, the second information is input to the second input unit 22. Then, the first control unit 25A changes the second display attribute value from the initial value to an intermediate value. As a result, the display state of the lower display unit 81 changes from green lighting (display state A) to green blinking state, and becomes the display state B. A person who has viewed the display state B can know that maintenance is currently being performed on the first mechanical device MA in a normal state.
　下表示部８１が緑点滅している表示状態Ｂで、作業者がメンテナンスを完了して第１操作部３Ａを１回押し操作すると、第２情報が第２入力部２２に入力される。すると、第１制御部２５Ａは、第２表示属性値を、中間値から完了値に変更する。これにより、下表示部８１の表示状態は、緑点滅（表示状態Ｂ）から緑色の閃光状態に変わり、表示状態Ｃとなる。表示状態Ｃを見た者は、正常状態にある第１機械装置ＭＡにおいてメンテナンスが完了したことを把握できる。 In the display state B in which the lower display section 81 is blinking green, when the operator completes the maintenance and presses the first operation section 3A once, the second information is input to the second input section 22. Then, the first control unit 25A changes the second display attribute value from the intermediate value to the completion value. As a result, the display state of the lower display unit 81 changes from blinking green (display state B) to a green flash state, and becomes the display state C. A person watching the display state C can know that the maintenance has been completed in the first mechanical device MA in the normal state.
　下表示部８１が緑閃光している表示状態Ｃで、作業者が第１操作部３Ａをもう１回押し操作すると、第２情報が第２入力部２２に入力される。すると、第１制御部２５Ａは、第２表示属性値を、完了値から初期値に変更する。これにより、下表示部８１の表示状態は、緑閃光（表示状態Ｃ）から緑色の連続点灯に変わり、表示状態Ａとなる。表示状態Ａを見た者は、第１機械装置ＭＡが正常動作中であってメンテナンス等が行われていないことを把握できる。 In the display state C in which the lower display section 81 is flashing green, when the operator presses the first operation section 3A once more, the second information is input to the second input section 22. Then, the first control unit 25A changes the second display attribute value from the completed value to the initial value. As a result, the display state of the lower display unit 81 changes from green flash (display state C) to green continuous lighting, and becomes the display state A. A person who looks at the display state A can understand that the first mechanical device MA is operating normally and maintenance is not performed.
　第１機械装置ＭＡにおける第１異常の発生を表わす第１情報が制御装置４Ａから第１入力部２１に入力されると、第１制御部２５Ａは、第１表示属性値を正常値から第１異常値に変更する。それにより、下表示部８１の光源９が消灯して、中表示部８２の光源９が黄色で発光する。このとき、第２表示属性値が初期値であれば、第１制御部２５Ａの制御によって、中表示部８２は黄色で連続点灯し、表示状態Ｄとなる。この状態で、作業者が第１異常を解消するために第１機械装置ＭＡにやってきて、作業開始に先立って第１操作部３Ａを１回押し操作する。この押し操作により、第２情報が第２入力部２２に入力される。すると、第１制御部２５Ａは、第２表示属性値を、初期値から中間値に変更する。これにより、中表示部８２の表示状態は、黄点灯（表示状態Ｄ）から黄色の点滅状態に変わり、表示状態Ｅに遷移する。表示状態Ｅを見た者は、第１異常が発生した第１機械装置ＭＡにおいて第１異常を解消するための対応が現在行われていることを把握できる。 When the first information indicating the occurrence of the first abnormality in the first mechanical device MA is input from the control device 4A to the first input unit 21, the first control unit 25A changes the first display attribute value from the normal value to the first value. Change to an abnormal value. Accordingly, the light source 9 of the lower display unit 81 is turned off, and the light source 9 of the middle display unit 82 emits yellow light. At this time, if the second display attribute value is the initial value, the middle display unit 82 is continuously lit in yellow and enters the display state D under the control of the first control unit 25A. In this state, the operator comes to the first mechanical device MA in order to eliminate the first abnormality, and presses the first operation unit 3A once before starting the operation. By this pressing operation, the second information is input to the second input unit 22. Then, the first control unit 25A changes the second display attribute value from the initial value to an intermediate value. As a result, the display state of the middle display section 82 changes from yellow lighting (display state D) to yellow blinking state, and transits to display state E. A person who has viewed the display state E can understand that the first mechanical device MA in which the first abnormality has occurred is currently taking measures to resolve the first abnormality.
　中表示部８２が黄点滅している表示状態Ｅで、作業者が作業を完了して第１操作部３Ａを１回押し操作すると、第２情報が第２入力部２２に入力される。すると、第１制御部２５Ａは、第２表示属性値を、中間値から完了値に変更する。これにより、中表示部８２の表示状態は、黄点滅（表示状態Ｅ）から黄色の閃光状態に変わり、表示状態Ｆに遷移する。表示状態Ｆを見た者は、第１異常が発生した第１機械装置ＭＡにおいて対応が完了したことを把握できる。 In the display state E in which the middle display section 82 is blinking yellow, when the operator completes the work and presses the first operation section 3A once, the second information is input to the second input section 22. Then, the first control unit 25A changes the second display attribute value from the intermediate value to the completion value. As a result, the display state of the middle display section 82 changes from blinking yellow (display state E) to a flashing yellow state, and transits to the display state F. A person who has viewed the display state F can know that the response has been completed in the first mechanical device MA in which the first abnormality has occurred.
　作業者が対応しても第１異常を解消できない場合がある。その場合には、作業者は、例えば表示状態Ｅから第１操作部３Ａを１回押し操作して中表示部８２を黄閃光させて表示状態Ｆとし、さらに、第１操作部３Ａをもう１回押し操作する。このとき、第１制御部２５Ａは、第２情報の第２入力部２２への入力に応じて、第２表示属性値を、中間値から完了値を経て初期値へと変更する。そのため、中表示部８２の表示状態は、黄点滅から黄閃光を経て黄点灯に変わり、表示状態Ｄとなる。表示状態Ｄを見た者は、第１機械装置ＭＡの第１異常が未解消であることを把握できる。 し て も The first abnormality may not be able to be resolved even if the operator responds. In this case, for example, the operator presses the first operation unit 3A once from the display state E to cause the middle display unit 82 to flash yellow to the display state F, and further press the first operation unit 3A again. Press twice. At this time, the first control unit 25A changes the second display attribute value from the intermediate value to the initial value through the completion value according to the input of the second information to the second input unit 22. Therefore, the display state of the middle display section 82 changes from blinking yellow to flashing yellow through yellow flashing, and becomes the display state D. A person who has viewed the display state D can know that the first abnormality of the first mechanical device MA has not been resolved.
　作業者の対応に応じて異常が解消されることにより、第１機械装置ＭＡの正常動作を表わす第１情報が制御装置４Ａから第１入力部２１に入力されると、第１制御部２５Ａは、第１表示属性値を異常値から正常値に変更する。これにより、中表示部８２の光源９が消灯して下表示部８１の光源９が緑色で発光する。中表示部８２が黄点灯中（表示状態Ｄ）または黄点滅中（表示状態Ｅ）であるにもかかわらず第１異常が自然解消される場合があり得る。この場合に、第１機械装置ＭＡの正常動作を表わす第１情報が制御装置４Ａから第１入力部２１に入力されると、第１制御部２５Ａは、中表示部８２を消灯して下表示部８１を緑点灯させたり緑点滅させたりする（表示状態Ａ，Ｂ）。逆に、第１異常が発生することによって、下表示部８１が消灯して中表示部８２が黄点灯したり黄点滅したり黄閃光したりすることもある（表示状態Ｄ，Ｅ，Ｆ）。 When the abnormality is eliminated according to the worker's response and the first information indicating the normal operation of the first mechanical device MA is input from the control device 4A to the first input unit 21, the first control unit 25A Change the first display attribute value from the abnormal value to the normal value. Accordingly, the light source 9 of the middle display unit 82 is turned off, and the light source 9 of the lower display unit 81 emits green light. The first abnormality may be naturally resolved even though the middle display section 82 is lit yellow (display state D) or blinking yellow (display state E). In this case, when the first information indicating the normal operation of the first mechanical device MA is input from the control device 4A to the first input unit 21, the first control unit 25A turns off the middle display unit 82 and displays the lower display. The unit 81 is lit green or flashes green (display states A and B). Conversely, when the first abnormality occurs, the lower display section 81 may be turned off and the middle display section 82 may turn on yellow, blink yellow, or flash yellow (display states D, E, and F). .
　第１機械装置ＭＡにおける第２異常の発生を表わす第１情報が制御装置４Ａから第１入力部２１に入力されると、第１制御部２５Ａは、第１表示属性値を正常値から第２異常値に変更する。それにより、下表示部８１の光源９が消灯して、上表示部８３の光源９が赤色で発光する。このとき、第２表示属性値が初期値であれば、第１制御部２５Ａの制御によって、上表示部８３は赤色で連続点灯し、表示状態Ｇとなる。この状態で、作業者が第２異常を解消するために第１機械装置ＭＡにやってきて、作業開始に先立って第１操作部３Ａを１回押し操作する。この押し操作により、第２情報が第２入力部２２に入力される。すると、第１制御部２５Ａは、第２表示属性値を、初期値から中間値に変更する。これにより、上表示部８３の表示状態は、赤点灯（表示状態Ｇ）から赤色の点滅状態に変わり、表示状態Ｈに遷移する。表示状態Ｈを見た者は、第２異常が発生した第１機械装置ＭＡにおいて第２異常を解消するための対応が現在行われていることを把握できる。 When the first information indicating the occurrence of the second abnormality in the first mechanical device MA is input from the control device 4A to the first input unit 21, the first control unit 25A changes the first display attribute value from the normal value to the second value. Change to an abnormal value. Accordingly, the light source 9 of the lower display unit 81 is turned off, and the light source 9 of the upper display unit 83 emits red light. At this time, if the second display attribute value is the initial value, the upper display unit 83 is continuously lit in red and enters the display state G under the control of the first control unit 25A. In this state, the operator comes to the first mechanical device MA in order to resolve the second abnormality, and presses the first operation unit 3A once before starting the operation. By this pressing operation, the second information is input to the second input unit 22. Then, the first control unit 25A changes the second display attribute value from the initial value to an intermediate value. Thus, the display state of the upper display unit 83 changes from red lighting (display state G) to red blinking state, and transits to the display state H. A person who has viewed the display state H can understand that the first mechanical device MA in which the second abnormality has occurred is currently taking measures to resolve the second abnormality.
　上表示部８３が赤点滅している表示状態Ｈで、作業者が作業を完了して第１操作部３Ａを１回押し操作すると、第２情報が第２入力部２２に入力される。すると、第１制御部２５Ａは、第２表示属性値を、中間値から完了値に変更する。これにより、上表示部８３の表示状態は、赤点滅（表示状態Ｈ）から赤色の閃光状態に変わり、表示状態Ｉに遷移する。表示状態Ｉを見た者は、第２異常が発生した第１機械装置ＭＡにおいて対応が完了したことを把握できる。 In the display state H in which the upper display unit 83 is blinking red, when the operator completes the work and presses the first operation unit 3A once, the second information is input to the second input unit 22. Then, the first control unit 25A changes the second display attribute value from the intermediate value to the completion value. As a result, the display state of the upper display unit 83 changes from flashing red (display state H) to a red flashing state, and transits to the display state I. A person watching the display state I can know that the response has been completed in the first mechanical device MA in which the second abnormality has occurred.
　作業者が対応しても第２異常を解消できない場合がある。その場合には、作業者は、例えば表示状態Ｈから第１操作部３Ａを１回押し操作して第１表示部８Ａを赤閃光させて表示状態Ｉとし、さらに、第１操作部３Ａをもう１回押し操作する。このとき、第１制御部２５Ａは、第２情報の第２入力部２２への入力に応じて、第２表示属性値を、中間値から完了値を経て初期値へと変更する。そのため、上表示部８３の表示状態は、赤点滅から赤閃光を経て赤点灯に変わり、表示状態Ｇとなる。表示状態Ｇを見た者は、第１機械装置ＭＡの第２異常が未解消であることを把握できる。 し て も The second abnormality may not be able to be resolved even if the operator responds. In this case, the operator presses the first operation unit 3A once, for example, from the display state H to cause the first display unit 8A to flash red to the display state I, and further press the first operation unit 3A again. Press once. At this time, the first control unit 25A changes the second display attribute value from the intermediate value to the initial value through the completion value according to the input of the second information to the second input unit 22. Therefore, the display state of the upper display unit 83 changes from flashing red to flashing red through red flash, and becomes the display state G. A person who has viewed the display state G can know that the second abnormality of the first mechanical device MA has not been resolved.
　作業者の対応に応じて異常が解消されることにより、第１機械装置ＭＡの正常動作を表わす第１情報が制御装置４Ａから第１入力部２１に入力されると、第１制御部２５Ａは、第１表示属性値を第２異常値から正常値に変更する。これにより、上表示部８３の光源９が消灯して下表示部８１の光源９が緑色で発光する。上表示部８３が赤点灯中（表示状態Ｇ）または赤点滅中（表示状態Ｈ）であるにもかかわらず第２異常が自然解消される場合があり得る。この場合に、第１機械装置ＭＡの正常動作を表わす第１情報が制御装置４Ａから第１入力部２１に入力されると、第１制御部２５Ａは、上表示部８３を消灯して下表示部８１を緑点灯させたり緑点滅させたりする（表示状態Ａ，Ｂ）。逆に、第２異常が発生することによって、下表示部８１が消灯して上表示部８３が赤点灯したり赤点滅したり赤閃光したりすることもある（表示状態Ｇ，Ｈ，Ｉ）。また、第２異常が解消しても、第１異常が発生することによって、上表示部８３が消灯して中表示部８２が黄点灯したり黄点滅したり黄閃光したりすることもある（表示状態Ｄ，Ｅ，Ｆ）。 When the abnormality is eliminated according to the worker's response and the first information indicating the normal operation of the first mechanical device MA is input from the control device 4A to the first input unit 21, the first control unit 25A Change the first display attribute value from the second abnormal value to a normal value. Accordingly, the light source 9 of the upper display unit 83 is turned off, and the light source 9 of the lower display unit 81 emits green light. Although the upper display unit 83 is lit red (display state G) or blinking red (display state H), the second abnormality may be naturally resolved. In this case, when the first information indicating the normal operation of the first mechanical device MA is input from the control device 4A to the first input unit 21, the first control unit 25A turns off the upper display unit 83 and displays the lower display. The unit 81 is lit green or flashes green (display states A and B). Conversely, when the second abnormality occurs, the lower display section 81 may be turned off and the upper display section 83 may be lit red, blink red, or flash red (display states G, H, and I). . Also, even if the second abnormality is resolved, the upper display 83 may be turned off and the middle display 82 may be lit yellow, blink yellow, or flash yellow due to the occurrence of the first abnormality ( Display states D, E, F).
　図３には、第３表示属性および第４表示属性のそれぞれの属性値が変化した場合における第２信号表示灯２Ｂの第２表示部８Ｂの表示状態の変化も示されている。前述したように、第１表示属性および第３表示属性は同じ表示属性であり、第２表示属性および第４表示属性は同じ表示属性である。そのため、第２表示部８Ｂの表示状態は、第１信号表示灯２Ａの第１表示部８Ａと同様に変化する。具体的には、第３入力部２３に入力される第３情報に伴う第３表示属性値の変化に応じて、第２表示部８Ｂの表示位置および表示色が変化する。そして、第４入力部２４に入力される第４情報に伴う第４表示属性値の変化に応じて、第２表示部８Ｂの点灯パターンが変化する。また、第３信号表示灯２Ｃ～第８信号表示灯２Ｈの表示部８の表示状態も、第１表示部８Ａおよび第２表示部８Ｂと同様に変化する。 FIG. 3 also shows a change in the display state of the second display portion 8B of the second signal indicator 2B when the respective attribute values of the third display attribute and the fourth display attribute change. As described above, the first display attribute and the third display attribute are the same display attribute, and the second display attribute and the fourth display attribute are the same display attribute. Therefore, the display state of the second display section 8B changes similarly to the first display section 8A of the first signal display lamp 2A. Specifically, the display position and the display color of the second display unit 8B change according to the change of the third display attribute value accompanying the third information input to the third input unit 23.

Is displayed. The information corresponding to the third information includes the graphic display 46B of the second signal indicator 2B. The information corresponding to the fourth information includes any one of the waiting display 47, the arrival display 48, and the completion display 49. As an example, in FIG. 4, in the second individual display area 45B, the graphic display 46B and the arrival display 48 are displayed side by side so as to be arranged side by side. The graphic display 46B and the arrival display 48 may be integrally displayed so as to overlap. The same applies to the case where the wait display 47 and the completion display 49 are displayed. In the second individual display area 45B, a part corresponding to the middle display part 82 in the graphic display 46B indicates that the maintenance worker has arrived at the second mechanical device MB in which the first abnormality has occurred (information indicating the display state E). And the arrival indicator 48. The third information in this case includes information on occurrence of an emergency (here, a first abnormality).
　一例として、第３個別表示領域４５Ｃには、第１異常が発生した第３機械装置ＭＣに保守作業者が到着して第１異常への対応を完了したこと（表示状態Ｆを表わす情報）が、図形表示４６Ｃにおいて中表示部８２に相当する部分の黄閃光と、完了表示４９とによって表示されている。一例として、第４個別表示領域４５Ｄには、第４機械装置ＭＤが正常であって保守作業が行われていないこと（表示状態Ａを表わす情報）が、図形表示４６Ｄにおいて下表示部８１に相当する部分の緑点灯によって表示されている。このときの第４個別表示領域４５Ｄには、待ち表示４７は表示されない。一例として、第５個別表示領域４５Ｅには、第１異常が発生した第５機械装置ＭＥに保守作業者が到着していないこと（表示状態Ｄを表わす情報）が、図形表示４６Ｅにおいて中表示部８２に相当する部分の黄点灯と、待ち表示４７とによって表示されている。 As an example, in the third individual display area 45C, the fact that the maintenance worker has arrived at the third mechanical device MC where the first abnormality has occurred and has completed the response to the first abnormality (information indicating the display state F) is displayed. Are displayed by the yellow flash of the portion corresponding to the middle display portion 82 in the graphic display 46C and the completion display 49. As an example, in the fourth individual display area 45D, the fact that the fourth mechanical device MD is normal and maintenance work is not performed (information representing the display state A) corresponds to the lower display unit 81 in the graphic display 46D. This is indicated by the green lighting of the part that does. At this time, the waiting display 47 is not displayed in the fourth individual display area 45D. As an example, in the fifth individual display area 45E, the fact that the maintenance worker has not arrived at the fifth mechanical device ME in which the first abnormality has occurred (information indicating the display state D) is indicated in the middle display section in the graphic display 46E. The portion corresponding to 82 is displayed in yellow and the waiting display 47.
　一例として、第６個別表示領域４５Ｆには、第２異常が発生した第６機械装置ＭＦに保守作業者が到着して第２異常への対応を完了したこと（表示状態Ｉを表わす情報）が、図形表示４６Ｆにおいて上表示部８３に相当する部分の赤閃光と、完了表示４９とによって表示されている。一例として、第７個別表示領域４５Ｇには、第７機械装置ＭＧが正常であって保守作業が行われていないこと（表示状態Ａを表わす情報）が、図形表示４６Ｇにおいて下表示部８１に相当する部分の緑点灯によって表示されている。一例として、第８個別表示領域４５Ｈには、保守作業者が正常運転中の第８機械装置ＭＨに到着して保守作業をしていること（表示状態Ｂを表わす情報）が、図形表示４６Ｈにおいて下表示部８１に相当する部分の緑点滅と、到着表示４８とによって表示されている。各個別表示領域４５では、待ち表示４７や到着表示４８や完了表示４９によって保守作業者の対応状況を把握できるので、当該対応状況を表わす点灯パターン（特に、点滅や閃光）が図形表示４６において再現されなくてもよい。 As an example, in the sixth individual display area 45F, the fact that the maintenance worker has arrived at the sixth mechanical device MF where the second abnormality has occurred and has completed the handling of the second abnormality (information indicating the display state I) is displayed. Are displayed by the red flash of the portion corresponding to the upper display portion 83 in the graphic display 46F and the completion display 49. As an example, in the seventh individual display area 45G, the fact that the seventh mechanical device MG is normal and maintenance work is not performed (information representing the display state A) corresponds to the lower display unit 81 in the graphic display 46G. This is indicated by the green lighting of the part that does. As an example, in the eighth individual display area 45H, the fact that the maintenance worker has arrived at the eighth mechanical device MH during normal operation and is performing maintenance work (information representing the display state B) is displayed in the graphic display 46H. This is indicated by the blinking green of the portion corresponding to the lower display section 81 and the arrival display 48. In each of the individual display areas 45, the response status of the maintenance worker can be grasped by the wait display 47, the arrival display 48, and the completion display 49, and the lighting pattern (in particular, blinking or flashing) representing the response status is reproduced in the graphic display 46. It does not have to be done.
　正常動作中の機械装置Ｍに対応する個別表示領域４５における表示サイズ（図形表示４６等の大きさ）を１００％とする（第４個別表示領域４５Ｄ、第７個別表示領域４５Ｇおよび第８個別表示領域４５Ｈを参照）。監視制御部４１は、第１異常や第２異常といった緊急事態が発生した機械装置Ｍに対応する個別表示領域４５における表示サイズを１００％よりも大きくする。これによって、監視制御部４１は、当該個別表示領域４５における図形表示４６、待ち表示４７、到着表示４８および完了表示４９を強調表示する（第１個別表示領域４５Ａ～第３個別表示領域４５Ｃおよび第５個別表示領域４５Ｅ～第６個別表示領域４５Ｆを参照）。具体的には、監視制御部４１は、保守作業員が到着済の機械装置Ｍに対応する図形表示４６と、到着表示４８とを、例えば１４０％の表示サイズで拡大表示する（第２個別表示領域４５Ｂを参照）。監視制御部４１は、保守作業員が緊急事態への対応を完了した機械装置Ｍに対応する図形表示４６と、完了表示４９とを、例えば１４０％の表示サイズで拡大表示する（第３個別表示領域４５Ｃおよび第６個別表示領域４５Ｆを参照）。一方、監視制御部４１は、保守作業員が到着していない機械装置Ｍに対応する図形表示４６と、待ち表示４７とを、さらに拡大して例えば２００％の表示サイズで表示する（第１個別表示領域４５Ａおよび第５個別表示領域４５Ｅを参照）。 The display size (the size of the graphic display 46 or the like) in the individual display area 45 corresponding to the mechanical device M that is operating normally is set to 100% (the fourth individual display area 45D, the seventh individual display area 45G, and the eighth individual display). (See region 45H). The monitoring control unit 41 sets the display size in the individual display area 45 corresponding to the mechanical device M in which the emergency such as the first abnormality or the second abnormality has occurred to be larger than 100%. Thereby, the monitoring control unit 41 highlights the graphic display 46, the waiting display 47, the arrival display 48, and the completion display 49 in the individual display area 45 (the first individual display area 45A to the third individual display area 45C and the (See 5 individual display area 45E to 6th individual display area 45F). Specifically, the monitoring control unit 41 enlarges and displays the graphic display 46 and the arrival display 48 corresponding to the machine device M to which the maintenance worker has arrived, for example, at a display size of 140% (second individual display). (See region 45B). The monitoring control unit 41 enlarges and displays the graphic display 46 and the completion display 49 corresponding to the machine device M for which the maintenance worker has completed the response to the emergency with a display size of, for example, 140% (third individual display). (See area 45C and sixth individual display area 45F). On the other hand, the monitoring control unit 41 further enlarges and displays the graphic display 46 and the waiting display 47 corresponding to the mechanical device M to which the maintenance worker has not arrived, for example, at a display size of 200% (first individual display). (See display area 45A and fifth individual display area 45E).
　第１信号表示灯２Ａの場合、保守作業員が第１機械装置ＭＡに到着したか否かや、保守作業員が第１機械装置ＭＡの緊急事態への対応を完了したか否かは、保守作業者による第１操作部３Ａの操作によって入力される第２情報に対応している。第１信号表示灯２Ａに対応する図形表示４６Ａの元となる第１情報が緊急事態発生に関する情報を含む場合に、監視制御部４１は、図形表示４６Ａが第２情報に応じて強調表示されるように監視表示部４３を制御する。そのため、緊急事態が発生した第１機械装置ＭＡに保守作業員が到着して第１操作部３Ａを操作した場合や、保守作業員が緊急事態への対応を完了して第１操作部３Ａを操作した場合には、第１機械装置ＭＡが正常である場合（図形表示４６Ｄを参照）と比べて、図形表示４６Ａが拡大表示される。そして、保守作業員が緊急事態発生中の第１機械装置ＭＡに到着していない場合には、図形表示４６Ａがさらに拡大して表示される。 In the case of the first signal indicator light 2A, whether the maintenance worker has arrived at the first mechanical device MA or whether the maintenance worker has completed the emergency response of the first mechanical device MA is determined by the maintenance. This corresponds to the second information input by the operation of the first operation unit 3A by the operator. When the first information that is the basis of the graphic display 46A corresponding to the first signal indicator light 2A includes information relating to the occurrence of an emergency, the monitoring control unit 41 causes the graphic display 46A to be highlighted according to the second information. The monitor display unit 43 is controlled as described above. Therefore, when the maintenance worker arrives at the first mechanical device MA in which the emergency has occurred and operates the first operation unit 3A, or when the maintenance worker completes the response to the emergency and operates the first operation unit 3A. When the operation is performed, the graphic display 46A is enlarged and displayed as compared with the case where the first mechanical device MA is normal (see the graphic display 46D). When the maintenance worker has not arrived at the first mechanical device MA in the event of an emergency, the graphic display 46A is further enlarged and displayed.
　第１個別表示領域４５Ａおよび第２個別表示領域４５Ｂだけを参照して、図形表示４６Ａにおける赤の表示色が示す第２異常は、図形表示４６Ｂにおける黄の表示色が示す第１異常よりも緊急度が高い。つまり、第１個別表示領域４５Ａに対応する第１情報は、第２個別表示領域４５Ｂに対応する第３情報よりも緊急度が高い情報を含む。この場合、監視制御部４１は、図形表示４６Ａが図形表示４６Ｂよりも拡大表示されるように監視表示部４３を制御してもよい。これにより、図形表示４６Ａは、図形表示４６Ｂよりも強調表示される。 Referring only to the first individual display area 45A and the second individual display area 45B, the second abnormality indicated by the red display color in the graphic display 46A is more urgent than the first abnormality indicated by the yellow display color in the graphic display 46B. High degree. That is, the first information corresponding to the first individual display area 45A includes information having a higher urgency than the third information corresponding to the second individual display area 45B. In this case, the monitoring control unit 41 may control the monitoring display unit 43 so that the graphic display 46A is displayed in a larger size than the graphic display 46B. As a result, the graphic display 46A is highlighted more than the graphic display 46B.
　第１表示属性値が正常値であり、且つ、第２表示属性値が中間値である場合がある（図３参照）。この場合には、第１情報が、第１個別表示領域４５Ａに対応する第１機械装置ＭＡが正常であることを表わす情報を含み、且つ、第２情報が、第１機械装置ＭＡの保守作業開始を表わす情報を含む。これに応じて、監視制御部４１は、第１機械装置ＭＡの予防的な保守作業が行われていると判断する。そのため、監視制御部４１は、図４の第８個別表示領域４５Ｈの表示内容と同様に、第１個別表示領域４５Ａにおいて、図形表示４６Ａにおいて下表示部８１に相当する部分を緑点滅させて、到着表示４８を表示する。 There are cases where the first display attribute value is a normal value and the second display attribute value is an intermediate value (see FIG. 3). In this case, the first information includes information indicating that the first mechanical device MA corresponding to the first individual display area 45A is normal, and the second information includes a maintenance operation of the first mechanical device MA. Contains information indicating the start. In response, the monitoring control unit 41 determines that preventive maintenance work on the first mechanical device MA is being performed. Therefore, the monitoring control unit 41 causes the portion corresponding to the lower display unit 81 in the graphic display 46A to blink green in the first individual display region 45A in the same manner as the display content of the eighth individual display region 45H in FIG. An arrival display 48 is displayed.
　このようにこの実施形態によれば、第１機械装置ＭＡでの異常の発生に伴って制御装置４Ａから出力された第１情報が第１信号表示灯２Ａの第１入力部２１に入力されると、第１制御部２５Ａは、異常の発生およびその内容を表わす情報を表示するように第１表示部８Ａを制御する（図３の表示状態ＤおよびＧ）。これにより、第１表示部８Ａに表示された情報を見た者は、異常の発生やその内容を把握できる。異常に対応するために駆けつけた者が第１操作部３Ａを操作することによって第２情報を第２入力部２２に入力すると、第１制御部２５Ａは、第２情報に対応する情報を表示するように第１表示部８Ａを制御する（表示状態ＥおよびＨ）。これにより、第１表示部８Ａに表示された情報を見た者は、異常への対応が開始されたことも把握できる。第１機械装置ＭＡでの異常が解消すると、異常の解消を表わす第１情報が、制御装置４Ａから出力されて第１入力部２１に入力される。すると、第１制御部２５Ａは、異常解消を表わす情報を表示するように第１表示部８Ａを制御する（表示状態Ａ～Ｃ）。これにより、第１表示部８Ａに表示された情報を見た者は、異常の解消を把握できる。 As described above, according to this embodiment, the first information output from the control device 4A in response to the occurrence of an abnormality in the first mechanical device MA is input to the first input unit 21 of the first signal indicator 2A. Then, first control unit 25A controls first display unit 8A to display information indicating the occurrence of the abnormality and the details thereof (display states D and G in FIG. 3). Thereby, a person who has viewed the information displayed on the first display unit 8A can grasp the occurrence of the abnormality and the details thereof. When a person who rushed to deal with the abnormality inputs the second information to the second input unit 22 by operating the first operation unit 3A, the first control unit 25A displays information corresponding to the second information. The first display unit 8A is controlled as described above (display states E and H). Accordingly, a person who has viewed the information displayed on the first display unit 8A can also understand that the response to the abnormality has been started. When the abnormality in the first mechanical device MA is eliminated, first information indicating the elimination of the abnormality is output from the control device 4A and input to the first input unit 21. Then, the first control unit 25A controls the first display unit 8A so as to display information indicating the elimination of the abnormality (display states A to C). Thereby, a person who has viewed the information displayed on the first display unit 8A can grasp the elimination of the abnormality.
　第１情報に対応する情報と第２情報に対応する情報とは、第１出力部２９Ａによって出力されて、監視用表示装置４０の受信部４２によって受信される。監視用表示装置４０では、監視制御部４１が、第１情報に対応する情報と第２情報に対応する情報とが関連付けられて表示されるように監視表示部４３を制御する。そのため、監視表示部４３の第１個別表示領域４５Ａには、第１機械装置ＭＡにおける異常有無および異常の内容を表わす第１情報（図形表示４６Ａ）と、異常等への対応状況を表わす第２情報（図４では、待ち表示４７）とが関連付けられて表示される。これにより、監視表示部４３を見た者は、第１機械装置ＭＡにおける異常有無および異常の内容だけでなく、第１機械装置ＭＡにおける異常等への対応状況も把握できる。つまり、第１信号表示灯２Ａの監視対象である第１機械装置ＭＡの状態だけでなく、当該監視対象への対応状況も監視用表示装置４０において把握できる。以上の結果、監視用表示装置４０は、第１信号表示灯２Ａからより多様な情報を取得して表示することが可能となり、それより、利便性を向上できる。 The information corresponding to the first information and the information corresponding to the second information are output by the first output unit 29A and received by the receiving unit 42 of the monitoring display device 40. In the monitoring display device 40, the monitoring control unit 41 controls the monitoring display unit 43 so that the information corresponding to the first information and the information corresponding to the second information are displayed in association with each other. Therefore, in the first individual display area 45A of the monitoring display unit 43, the first information (graphic display 46A) indicating the presence or absence of the abnormality and the content of the abnormality in the first mechanical device MA, and the second information indicating the response status to the abnormality or the like. The information (the wait display 47 in FIG. 4) is displayed in association with the information. Accordingly, a person who has viewed the monitoring display unit 43 can grasp not only the presence or absence of the abnormality in the first mechanical device MA and the content of the abnormality, but also the response status to the abnormality and the like in the first mechanical device MA. That is, not only the state of the first mechanical device MA, which is the monitoring target of the first signal display lamp 2A, but also the status of the response to the monitoring target can be grasped on the monitoring display device 40. As a result, the monitoring display device 40 can acquire and display more various information from the first signal indicator lamp 2A, thereby improving the convenience.
　また、第１情報に対応する情報と、第２情報に対応する情報とは、一体表示または並列表示されることによって、確実に関連付けられて第１個別表示領域４５Ａに表示される。これにより、第１個別表示領域４５Ａを見た者は、第１信号表示灯２Ａに対応付けられた第１機械装置ＭＡでの異常の発生および内容を表わす第１情報だけでなく、この異常への対応状況に関する第２情報も確実に把握できる。つまり、第１信号表示灯２Ａの監視対象である第１機械装置ＭＡの状態だけでなく、当該監視対象への対応状況も監視用表示装置４０において確実に把握できる。例えば、待ち表示４７が表示された第１個別表示領域４５Ａを見た者は、第１個別表示領域４５Ａに対応する第１機械装置ＭＡにおける異常状態の継続は、保守作業者の不在に起因することを把握できる。一方、第１個別表示領域４５Ａにおいて、完了表示４９が表示されたものの図形表示４６Ａの表示色が赤または黄のままになっている場合がある。このときの第１個別表示領域４５Ａを見た者は、第１個別表示領域４５Ａにおける異常状態の継続は、第１機械装置ＭＡの異常が保守作業によって解消されなかったことに起因することを把握できる。 {Circle around (1)} The information corresponding to the first information and the information corresponding to the second information are displayed in the first individual display area 45 </ b> A by being integrally displayed or displayed side by side, thereby being reliably associated with each other. As a result, the person who has viewed the first individual display area 45A can take action not only on the first information indicating the occurrence and content of the abnormality in the first mechanical device MA associated with the first signal display lamp 2A, but also on this abnormality. The second information relating to the response status can be grasped without fail. That is, not only the state of the first mechanical device MA, which is the monitoring target of the first signal indicator light 2A, but also the status of the response to the monitoring target can be reliably grasped on the monitoring display device 40. For example, a person who looks at the first individual display area 45A on which the waiting display 47 is displayed indicates that the continuation of the abnormal state in the first mechanical device MA corresponding to the first individual display area 45A is caused by the absence of a maintenance worker. I can understand that. On the other hand, in the first individual display area 45A, the display color of the graphic display 46A may remain red or yellow although the completion display 49 is displayed. The person viewing the first individual display area 45A at this time understands that the continuation of the abnormal state in the first individual display area 45A is caused by the fact that the abnormality of the first mechanical device MA has not been eliminated by the maintenance work. it can.
　第２機械装置ＭＢでの異常の発生に伴って制御装置４Ｂから出力された第３情報が第３入力部２３に入力されると、第２制御部２５Ｂは、異常発生およびその内容を表わす情報を表示するように第２表示部８Ｂを制御する（図３の表示状態ＤおよびＧ）。これにより、第２表示部８Ｂに表示された情報を見た者は、異常の発生を把握できる。異常に対応するために駆けつけた者が第２操作部３Ｂを操作することによって第４情報を第４入力部２４に入力すると、第２制御部２５Ｂは、第４情報に対応する情報を表示するように第２表示部８Ｂを制御する（表示状態ＥおよびＨ）。これにより、第２表示部８Ｂに表示された情報を見た者は、異常への対応が開始されたことも把握できる。第２機械装置ＭＢでの異常が解消すると、異常の解消を表わす第３情報が、制御装置４Ｂから出力されて第３入力部２３に入力される。すると、第２制御部２５Ｂは、異常解消を表わす情報を表示するように第２表示部８Ｂを制御する（表示状態Ａ～Ｃ）。これにより、第２表示部８Ｂに表示された情報を見た者は、異常の解消を把握できる。 When the third information output from the control device 4B in response to the occurrence of the abnormality in the second mechanical device MB is input to the third input unit 23, the second control unit 25B outputs the information indicating the occurrence of the abnormality and the content thereof. Is displayed (display states D and G in FIG. 3). Thereby, a person who has viewed the information displayed on the second display unit 8B can grasp the occurrence of the abnormality. When the person who rushed to deal with the abnormality inputs the fourth information to the fourth input unit 24 by operating the second operation unit 3B, the second control unit 25B displays the information corresponding to the fourth information. The second display section 8B is controlled as described above (display states E and H). Thereby, a person who has viewed the information displayed on the second display unit 8B can also understand that the response to the abnormality has been started. When the abnormality in the second mechanical device MB is eliminated, the third information indicating the elimination of the abnormality is output from the control device 4B and input to the third input unit 23. Then, the second control unit 25B controls the second display unit 8B to display the information indicating the elimination of the abnormality (display states A to C). Thus, a person who has viewed the information displayed on the second display unit 8B can grasp the elimination of the abnormality.
　第３情報に対応する情報と第４情報に対応する情報とは、第２出力部２９Ｂによって出力されて、監視用表示装置４０の受信部４２によって受信される。監視用表示装置４０では、監視制御部４１が、第３情報に対応する情報と第４情報に対応する情報とが関連付けられて表示されるように監視表示部４３を制御する。そのため、監視表示部４３の第２個別表示領域４５Ｂには、第２機械装置ＭＢにおける異常有無および異常の内容を表わす第３情報（図形表示４６Ｂ）と、異常等への対応状況を表わす第４情報（図４では、到着表示４８）とが関連付けられて表示される。これにより、監視表示部４３を見た者は、第２機械装置ＭＢにおける異常有無および異常の内容だけでなく、第２機械装置ＭＢにおける異常等への対応状況も把握できる。つまり、第２信号表示灯２Ｂの監視対象である第２機械装置ＭＢの状態だけでなく、当該監視対象への対応状況も監視用表示装置４０において把握できる。以上の結果、監視用表示装置４０は、第２信号表示灯２Ｂからより多様な情報を取得して表示することが可能となり、それより、利便性を一層向上できる。 The information corresponding to the third information and the information corresponding to the fourth information are output by the second output unit 29B and received by the receiving unit 42 of the monitoring display device 40. In the monitoring display device 40, the monitoring control unit 41 controls the monitoring display unit 43 so that the information corresponding to the third information and the information corresponding to the fourth information are displayed in association with each other. Therefore, in the second individual display area 45B of the monitor display unit 43, the third information (graphic display 46B) indicating the presence or absence of the abnormality and the content of the abnormality in the second mechanical device MB, and the fourth information indicating the response status to the abnormality or the like are displayed. The information (the arrival display 48 in FIG. 4) is displayed in association with the information. Thus, a person who has viewed the monitoring display unit 43 can grasp not only the presence or absence of the abnormality in the second mechanical device MB and the content of the abnormality, but also the response status to the abnormality and the like in the second mechanical device MB. That is, the monitoring display device 40 can grasp not only the state of the second mechanical device MB, which is the monitoring target of the second signal display lamp 2B, but also the status of response to the monitoring target. As a result, the monitoring display device 40 can acquire and display more various information from the second signal indicator lamp 2B, thereby further improving the convenience.
　また、第３情報に対応する情報と、第４情報に対応する情報とは、一体表示または並列表示されることによって、確実に関連付けられて第２個別表示領域４５Ｂに表示される。これにより、第２個別表示領域４５Ｂを見た者は、第２信号表示灯２Ｂに対応付けられた第２機械装置ＭＢでの異常の発生および内容を表わす第３情報だけでなく、この異常への対応状況に関する第４情報も確実に把握できる。つまり、第２信号表示灯２Ｂの監視対象である第２機械装置ＭＢの状態だけでなく、当該監視対象への対応状況も監視用表示装置４０において確実に把握できる。 (4) The information corresponding to the third information and the information corresponding to the fourth information are displayed in the second individual display area 45B by being integrally displayed or displayed side by side so as to be surely associated with each other. As a result, the person who has viewed the second individual display area 45B can take action not only on the third information indicating the occurrence and content of the abnormality in the second mechanical device MB associated with the second signal display lamp 2B, but also on this abnormality. The fourth information relating to the response status can be grasped without fail. That is, not only the state of the second mechanical device MB, which is the monitoring target of the second signal indicator light 2B, but also the status of response to the monitoring target can be reliably grasped on the monitoring display device 40.
　また、第１情報が、緊急事態発生に関する情報を含む場合に、監視制御部４１は、第１情報に対応する情報が第２情報に応じて強調表示されるように監視表示部４３を制御する（図４の図形表示４６Ａを参照）。そのため、監視表示部４３の第１個別表示領域４５Ａにおいて強調表示された図形表示４６Ａを見た者は、第１機械装置ＭＡに緊急事態が発生したことを確実に把握できる。 When the first information includes information on occurrence of an emergency, the monitoring control unit 41 controls the monitoring display unit 43 so that information corresponding to the first information is highlighted according to the second information. (See graphic display 46A in FIG. 4). Therefore, a person who sees the graphic display 46A highlighted in the first individual display area 45A of the monitor display unit 43 can surely grasp that an emergency has occurred in the first mechanical device MA.
　また、第１情報が、第３情報よりも緊急度が高い情報を含む場合に、監視制御部４１は、第１情報に対応する情報が第３情報に対応する情報よりも強調表示されるように監視表示部４３を制御する。そのため、監視表示部４３において第３情報に対応する情報（ここでは、図形表示４６Ｂ）と当該情報よりも強調表示された第１情報に対応する情報（ここでは、図形表示４６Ａ）とを見た者は、第１機械装置ＭＡで生じた事象の緊急度が第２機械装置ＭＢで生じた事象の緊急度よりも高いことを把握できる。 When the first information includes information having a higher degree of urgency than the third information, the monitoring control unit 41 causes the information corresponding to the first information to be displayed more emphasized than the information corresponding to the third information. The monitor display unit 43 is controlled. Therefore, the monitoring display unit 43 looks at information corresponding to the third information (here, the graphic display 46B) and information corresponding to the first information (here, the graphic display 46A) which is displayed more emphasized than the information. The person can understand that the urgency of the event that has occurred in the first mechanical device MA is higher than the urgency of the event that has occurred in the second mechanical device MB.
　第１信号表示灯２Ａの図形表示４６Ａの強調度合い（この実施形態では、表示サイズ）によって、第１信号表示灯２Ａに対応付けられた第１機械装置ＭＡに生じた事象の緊急度を監視表示部４３に表示できる。この場合、図形表示４６Ａと到着表示４８とが関連付けられて表示された監視表示部４３を見た者は、第１機械装置ＭＡに生じた事象の緊急度と、保守作業者が第１機械装置ＭＡに到着したこととを把握できる。そして、到着表示４８から完了表示４９に切り替わったことを見た者は、第１機械装置ＭＡの保守作業完了を把握できる。同様に、第２信号表示灯２Ｂの図形表示４６Ｂの強調度合いによって、第２信号表示灯２Ｂに対応付けられた第２機械装置ＭＢに生じた事象の緊急度を監視表示部４３に表示できる。この場合、図形表示４６Ｂと到着表示４８とが関連付けて表示された監視表示部４３を見た者は、第２機械装置ＭＢに生じた事象の緊急度と、保守作業者が第２機械装置ＭＢに到着したこととを把握できる。そして、到着表示４８から完了表示４９に切り替わったことを見た者は、第２機械装置ＭＢの保守作業完了を把握できる。そして、監視表示部４３において、第２信号表示灯２Ｂの図形表示４６Ｂと、図形表示４６Ｂよりも強調表示された第１信号表示灯２Ａの図形表示４６Ａとを見た者は、第１機械装置ＭＡに生じた事象の緊急度が第２機械装置ＭＢに生じた事象の緊急度よりも高いことを確実に把握できる。 The degree of urgency of an event occurring in the first mechanical device MA associated with the first signal indicator 2A is monitored and displayed according to the degree of emphasis (display size in this embodiment) of the graphic display 46A of the first signal indicator 2A. It can be displayed on the unit 43. In this case, the person who has watched the monitor display unit 43 in which the graphic display 46A and the arrival display 48 are displayed in association with each other indicates that the urgency of the event that has occurred in the first mechanical device MA and that the maintenance worker has the first mechanical device You can know that you have arrived at MA. Then, a person who has seen the switch from the arrival display 48 to the completion display 49 can grasp the completion of the maintenance work of the first mechanical device MA. Similarly, the degree of urgency of an event that has occurred in the second mechanical device MB associated with the second signal indicator light 2B can be displayed on the monitor display unit 43 based on the degree of emphasis of the graphic display 46B of the second signal indicator light 2B. In this case, the person who has watched the monitor display unit 43 in which the graphic display 46B and the arrival display 48 are displayed in association with each other indicates that the urgency of the event that has occurred in the second mechanical device MB and that the maintenance worker has the second mechanical device MB And that it has arrived. Then, a person who has seen the switch from the arrival display 48 to the completion display 49 can know the completion of the maintenance work of the second mechanical device MB. Then, in the monitoring display unit 43, the person who sees the graphic display 46B of the second signal display light 2B and the graphic display 46A of the first signal display light 2A that is more emphasized than the graphic display 46B is the first mechanical device. It is possible to reliably grasp that the urgency of the event that has occurred in the MA is higher than the urgency of the event that has occurred in the second mechanical device MB.
　また、第１機械装置ＭＡが正常であることを表わす情報と、第１機械装置ＭＡの保守作業開始を表わす情報とを受信した監視用表示装置４０では、監視制御部４１が、正常な第１機械装置ＭＡにおいて異常についての予防的な保守作業が行われていることを判断する。この場合、監視表示部４３には、正常な第１機械装置ＭＡにおいて予防的な保守作業が行われていることを表示できる（図４の第８個別表示領域４５Ｈの表示内容を参照）。そのため、監視表示部４３を見た者は、第１機械装置ＭＡにおいて異常が発生していないものの予防的な保守作業が行われていることを把握できる。以上では、監視表示部４３において第１信号表示灯２Ａおよび第２信号表示灯２Ｂに関連する表示によって得られる効果について説明したが、同様の効果は、監視表示部４３において他の第３信号表示灯２Ｃ～第８信号表示灯２Ｈに関連する表示によっても得られる。 Further, in the monitoring display device 40 that has received the information indicating that the first mechanical device MA is normal and the information indicating that the maintenance work of the first mechanical device MA has started, the monitoring control unit 41 determines whether the normal first mechanical device MA is operating normally. It is determined that preventive maintenance work for an abnormality is being performed in the mechanical device MA. In this case, the monitor display unit 43 can display that preventive maintenance work is being performed on the normal first mechanical device MA (see the display contents of the eighth individual display area 45H in FIG. 4). Therefore, a person who has watched the monitoring display unit 43 can know that preventive maintenance work is being performed although no abnormality has occurred in the first mechanical device MA. In the above, the effect obtained by the display related to the first signal indicator light 2A and the second signal indicator light 2B on the monitor display unit 43 has been described. It can also be obtained by the display related to the lamps 2C to 8H.

In the following, portions that are functionally the same as the portions described with respect to the above-described embodiment will be assigned the same reference numerals, and detailed description of those portions will be omitted. As the signal display lamp 2, there may be a configuration in which the display unit 8 includes only one of the lower display unit 81, the middle display unit 82, and the upper display unit 83, instead of the above-described stacked signal lamp. With reference to first signal indicator light 2A, display unit 8 of signal indicator light 2 according to the modification includes light source 51 and cylindrical globe 52 surrounding light source 51. The light source 51 is a light emitting diode and selectively emits light of a plurality of colors. That is, the light source 51 is a full-color light source or a multi-color light source capable of emitting light of a plurality of colors. The signal indicator lamp 2 according to the modification may be a rotation warning lamp in which the light source 51 is configured to be rotatable. The globe 52 is formed in a truncated conical shape having a smaller diameter as the distance from the base 6 increases. The globe 52 of this embodiment is colorless and transparent or white translucent, and emits light emitted from the light source 51 to the outside in the same color. The emission color of the light source 51 on the display unit 8 is the display color of the display unit 8. As in the above-described embodiment, the display color of the display unit 8 is one of green, yellow, and red, and the lighting pattern of the display unit 8 is one of lighting, blinking, and flashing. The signal indicator lamp 2 according to the modified example variably displays information of the corresponding mechanical device M by a display color or a lighting pattern.

　以上、この発明の実施形態について説明してきたが、この発明は、さらに他の形態で実施することもできる。 Although the embodiments of the present invention have been described above, the present invention can be embodied in other forms.
（１）例えば、保守作業者が作業を完了して第１操作部３Ａを押し操作すると、第１信号表示灯２Ａの第１制御部２５Ａは、第２表示属性値を中間値から完了値に変更することによって表示部８を閃光させる。しかし、表示部８は閃光しなくてもよい。つまり、前述した表示状態Ｃ，Ｆ，Ｉ（図３参照）が省略されてもよい。この場合、第１制御部２５Ａは、第２表示属性値を中間値から完了値に変更することによって表示部８の点灯パターンを点滅から点灯に変更する。 (1) For example, when the maintenance worker completes the work and pushes the first operation unit 3A, the first control unit 25A of the first signal indicator 2A changes the second display attribute value from the intermediate value to the completion value. The display unit 8 is caused to flash by changing. However, the display unit 8 does not have to flash. That is, the display states C, F, and I (see FIG. 3) described above may be omitted. In this case, the first control unit 25A changes the lighting pattern of the display unit 8 from blinking to lighting by changing the second display attribute value from the intermediate value to the completion value.
（２）監視用表示装置４０の監視制御部４１は、個別表示領域４５において図形表示４６の強調表示する際に、当該個別表示領域４５の見出し５０（図４参照）も強調表示してもよい。見出し５０の強調表示の一例として、監視制御部４１は、対象となる個別表示領域４５の見出し５０の背景や文字を他の個別表示領域４５の見出し５０の背景や文字よりも目立つ色で表示する。一例として、正常動作中の機械装置Ｍに対応する個別表示領域４５の見出し５０の背景色は白に設定されて、文字色は黒に設定される。第１異常や第２異常が発生したものの保守作業員が到着していない機械装置Ｍに対応する個別表示領域４５の見出し５０では、文字色は白に設定され、背景色は、最も目立つ色（黒等）に設定される。第１異常や第２異常が発生して保守作業員が到着済であったり、対応が完了済であったりする機械装置Ｍに対応する個別表示領域４５の見出し５０では、文字色は黒のままであるが、背景色は、白よりは目立つものの黒よりは目立たない色に設定される。 (2) When the graphic display 46 is highlighted in the individual display area 45, the monitoring control unit 41 of the monitoring display device 40 may also highlight the heading 50 (see FIG. 4) of the individual display area 45. . As an example of the highlighting of the heading 50, the monitoring control unit 41 displays the background and the character of the heading 50 of the target individual display area 45 in a color more prominent than the background and the character of the heading 50 of the other individual display area 45. . As an example, the background color of the heading 50 of the individual display area 45 corresponding to the machine device M that is operating normally is set to white, and the character color is set to black. In the heading 50 of the individual display area 45 corresponding to the machine device M in which the first abnormality or the second abnormality has occurred but the maintenance worker has not arrived, the character color is set to white, and the background color is set to the most prominent color ( Black). In the heading 50 of the individual display area 45 corresponding to the mechanical device M in which the first abnormality or the second abnormality has occurred and the maintenance worker has arrived or the response has been completed, the character color remains black. However, the background color is set to be more prominent than white but less prominent than black.
