FIG. 3 is an example of a control circuit diagram (ladder diagram) illustrating the circuit data stored in the circuit data management unit of the comparison display system according to the first embodiment of the present invention. FIG. 4 is a table showing an example of the contents of the specification data stored in the specification data management unit of the comparison display system according to the first embodiment of the present invention. FIG. 5 is an example of a calculation result of the calculation execution unit of the comparison display system according to the first embodiment of the present invention. FIG. 6 is an example of an image displayed by the image display unit of the comparison display system according to the first embodiment of the present invention.

  Hereinafter, a specific example will be described. In the control circuit 51 represented by FIG. 3, a case where four relays are replaced with relays having different operation times and return times will be described as an example.

  As an example, the control circuit 51 before replacement will be described with reference to FIG.

  The control circuit 51 includes a start circuit 52, an A system circuit 53, a B system circuit 54, and an end circuit 55.

  The start circuit 52 includes a switch 56 and a coil “Y0” of the relay “0” connected in series.

  The A system circuit 53 is a control circuit including four circuits 57-60. Hereinafter, the coil of the relay ΔΔ is represented as “YΔΔ”, the normally open contact of the relay ΔΔ is represented as “XΔΔa”, and the normally closed contact is represented as “XΔΔb”.

  In the circuit 57, the normally open contact X0A of the relay 0, the normally closed contact X4A of the relay 4A connected in series and the normally closed contact X1A of the relay 1A are connected in parallel (OR circuit), and these are the coils of the relay 1A. Y1A is connected in series. The normally open contact X0Aa of the relay 0 is closed (turned on) after the operation time has elapsed when a current flows through the coil Y0. The normally open contact X1Aa of the relay 1A is closed after the operation time has elapsed when a current flows through the coil Y1A. Further, the normally closed contact X4Ab of the relay 4A closes (turns OFF) after the operation time has elapsed when a current flows through the coil Y4A.

  In the circuit 58, the normally open contact X1Aa of the relay 1A and the coil Y2A of the relay 2A are connected in series. When the current flows through the coil Y1A of the relay 1A, the normally open contact X1Aa of the relay 1A is closed after the operation time has elapsed.

  In the circuit 59, the normally open contact X2Aa of the relay 2A and the coil Y3A are connected in series. When the current flows through the coil Y2A of the relay 2A, the normally open contact X2Aa of the relay 2A is closed after the operation time has elapsed.

  In the circuit 60, the normally open contact X3Aa of the relay 3A and the coil Y4A of the relay 4A are connected in series. When the current flows through the coil Y3A of the relay 3A, the normally open contact X3Aa of the relay 3A is closed after the operation time has elapsed.

  The B system circuit 54 is a control circuit including four circuits 61 to 64. The configuration of the four circuits 61 to 64 is the same as that of the four circuits 57 to 60 of the A system circuit 53, respectively.

  In the end circuit 55, the normally open contact X4Aa of the relay 4A and the normally open contact X4Ba of the relay 4B are connected in series (AND circuit). Therefore, a signal is input to the input contact 65 during the time when the normally open contact X4Aa of the relay 4A and the normally open contact X4Ba of the relay 4B are simultaneously closed.

  In all the relays constituting the control circuit 51, the respective contacts are opened and closed 50 msec after the current flows in each coil. That is, the operation time of these relays is 50 msec. Further, all the relays constituting the control circuit 51 open and close each contact 50 msec after the current flowing through each coil stops. That is, the return time of these relays is 50 msec.

  As can be seen from the above, the relay 1A and the relay 1B are the same type of relay. Relays 2A to 4A and relays 2B to 4B are the same type of relays. As an example, the model name of the relay 0 (so-called “model number”) is “R01”, the model names of the relay 1A and the relay 1B are “R02”, and the model names of the relays 2A to 4A and the relays 2B to 4B are “R03”. .

  As an example, the control circuit after replacement will be described.

  The control circuit after replacement replaces the relay 1A (model name “R02”) constituting the A-system circuit 53 of the control circuit 51 before replacement with a relay (model name “R04”) having an operation time and a recovery time of 10 msec. In addition, the relays 2A to 4A (model name “R03”) are replaced with relays (model name “R05”) having an operation time and a recovery time of 10 msec. The relay connection status has not changed.

  The circuit data stored in the circuit data management unit 2 and the specification data stored in the specification data management unit 3 will be described.

  The circuit data is information including a plurality of electric elements constituting the control circuit, connection states of the electric elements, and model names of the electric elements. The circuit data is, for example, CAD data of the control circuit.

  To explain using the above-described specific example, the circuit data of the control circuit 51 before replacement (circuit data before replacement) includes switches and a plurality of relays constituting the control circuit 51, their connection states, and their model names. This information includes the relay operation time and return time.

  Here, since the control circuit after replacement is obtained by replacing the four relays 1A to 4A constituting the control circuit 51 before replacement with different types of relays, the circuit data after replacement is the model name in the circuit data before replacement. Only the information on is the rewritten data.

  On the other hand, the specification data is information including model names of a plurality of electrical elements constituting the control circuit before and after replacement, and electrical characteristics for each model.

  To explain using the above-described specific example, as shown in FIG. 4, the specification data includes the model names of the switches and the plurality of relays constituting the control circuit before and after replacement, and the operation time and the return time for each of these models. It contains information.

  The combined data generation unit 4 and the combined data will be described.

  The combined data generation unit 4 reads circuit data before replacement and circuit data after replacement from the circuit data management unit 2 (S2).

  To explain using the above specific example, the combined data generation unit 4 includes the model names (“R01” to “R03”) included in the circuit data before replacement and the model names (“R01”) of the electrical elements of the circuit data after replacement. To “R05”), and the electrical characteristics (relay operating time and recovery time) for each type are read from the specification data management unit 3.

  The combined data generation unit 4 generates pre-exchange combined data in which electrical characteristics (operation times and return times of the relays “R01” to “R03”) are written in the pre-exchange circuit data. In addition, post-replacement combined data in which electrical characteristics (operation times and return times of the relays “R01” to “R05”) are written in the post-replacement circuit data is generated.

  The combined data generation unit 4 outputs the generated combined data before exchange and combined data after exchange to the combined data input unit 11.

  The condition data input unit 12 and the condition data will be described.

  The condition data includes the position (that is, the confirmation point) in the control circuit where the calculation execution unit 13 calculates the time, the type of time calculated by the calculation execution unit 13 (whether the time is the signal ON time, the signal OFF time, the signal ON Time and signal OFF time), and information on the initial conditions for executing the control.

  In the control circuit before and after replacement shown as a specific example above, the user desires the signal ON time and the signal OFF time at the normally open contacts and the input contacts 65 of the relays 0, 1A to 4A and 1B to 4B. Explained as an example.

  In this case, the user uses a keyboard or other input terminal to check the confirmation points (relays 0, 1A to 4A, 1B to 4B normally open contacts and input contacts 65) and the desired time type (signal ON). Time and signal OFF time). In addition, the user designates an initial condition for executing the control (time for turning on the switch of the start circuit 52 (for example, 100 msec)).

  The condition data input unit 12 inputs condition data including these pieces of information (S5), and outputs the input condition data to the calculation execution unit 13.

  The condition data input unit 12 may include an input terminal such as a keyboard and a mouse.

  The calculation execution part 13 and a calculation result are demonstrated.

  The calculation execution unit 13 inputs the pre-exchange combination data and the post-exchange combination data from the combination data input unit 11, and inputs the condition data from the condition data input unit.

  The calculation execution unit 13 outputs the calculation result shown in FIG. 5 when the pre-exchange combination data and post-exchange combination data and condition data given as examples above are input.

  The calculation result shown in FIG. 5 will be described. The calculation execution unit 13 calculates the signal ON time and the signal OFF time for each confirmation point before and after the exchange with the switch ON time as time 0 (S6).

  Further, the “signal ON / OFF switching order” in FIG. 5 will be described. The calculation execution unit 13 assigns serial numbers to the signal ON time and the signal OFF time in descending order of the signal ON / OFF switching time before and after the exchange. When there are a plurality of identical times, serial numbers are assigned in order from the top of the table.

  Note that the calculation execution unit 13 does not necessarily need to output the signal ON / OFF switching order. Whether or not the order is output may be selected by the user. Further, when there are a plurality of the same time, the same number may be assigned to these times.

  The image data generation unit 14, the image data, and the image display unit 5 will be described.

  The image data generation unit 14 receives the calculation result output by the calculation execution unit 13, and generates image data for displaying an image by the image display unit 5 based on the calculation result (S7).

  The image shown in FIG. 6 will be described. The image shown in FIG. 6 is generated based on the calculation result shown in FIG. 5 and is displayed on the image display unit (for example, monitor) 5.

  On the monitor, the signal ON / OFF state of each confirmation point is displayed side by side before and after replacement. A time axis is provided in the horizontal direction of the monitor, and the rising space hatched in FIG. 6 represents the signal ON state. The rising portion indicates the signal ON time of FIG. 5, and the falling portion indicates the signal OFF time of FIG.

  In FIG. 6, the rising space is hatched, but the rising space may be colored on an actual monitor. In this case, the rising space of the same confirmation point (for example, X1Aa before exchange and X1Aa after exchange) before and after the exchange is colored with the same color.

  In this specific example, it can be seen that no signal is detected at the input contact after replacement. This indicates that there is a problem that the final control operation of the control circuit of this specific example is not executed. In such a case, it is preferable that the rising space of the input contact 65 before replacement is colored with a color that is more conspicuous than the rising spaces of other confirmation points. Alternatively, the rising space of the input contact 65 before replacement may blink.

  Also, the numbers in parentheses in FIG. 6 indicate the order of switching the signal ON / OFF at each confirmation point.

  As can be seen from the above, the use of the comparison display system 1 is effective when the electric elements that have a time effect on the signal ON time or the signal OFF time at any position in the control circuit are replaced. Is. Examples of the electric element that affects the signal ON time or the signal OFF time temporally include a relay, an auxiliary relay, or a timer.

  Hereinafter, effects of the comparison display device, the comparison display system, the comparison display program, and the comparison display method according to the present embodiment will be described.

  According to the present embodiment, it is possible to simultaneously compare and display changes in the signal ON time or the signal OFF time at an arbitrary position in the control circuit before and after the replacement of the electric element. Therefore, the verification check work of the control operation when replacing the electric element is facilitated, the time required for the work can be shortened, and the accuracy of the work is improved.

  In addition, according to the present embodiment, changes in signal ON time or signal OFF time at a plurality of positions can be compared and displayed simultaneously. Therefore, if there is a problem due to the replacement in the verification check operation of the control operation when replacing the electric element, the problem can be easily found.

  Further, according to the present embodiment, when the display space is displayed by the image display unit 5, the rising space of the same confirmation point is colored with the same color before and after the replacement, so that the verification operation of the control operation at each position is confirmed. Becomes easier.

  Furthermore, according to the present embodiment, since the order of switching the signal ON / OFF at each confirmation point is displayed, the verification confirmation work of the control operation becomes easier.
