If there is a next page on the setting item selection screen, the setting items should be displayed in the order of the setting values that are changed more frequently, and setting items whose setting values are not normally changed should always be displayed on the next page, or It may be configured such that it is not displayed unless a special key is operated, and in this case, incorrect settings due to erroneous operations are reduced.

Note that the mode switching key 76 on the setting item selection screen functions as a key to return the display screen to the previous display screen, and in the state shown in FIG.
If is operated, the screen returns to the bank selection screen shown in FIG. For example, if the heating time is selected and set in the state shown in FIG. 10, a set value change screen is displayed.

FIG. 11 shows this setting value change screen. In this setting value change screen, the current setting value is displayed, and "h", "m" etc. are displayed according to the parameters (contents of address $0010) written in the type $C012 area of the control area of the system RAM 44. A time unit display is displayed, and the touch switch 30 provides a plus key 80 and a minus key 82 for each digit of the set value. By operating these keys 80 and 82, the set value is changed in an up-down manner.

The setting display 10 also displays the operating status on the display section 28 based on information transmitted from each control device through communication. In this case as well, the time unit "s", temperature unit "°C", and decimal point position are displayed in accordance with each parameter written in the type $C012 area of the control area of the system RAM 44, as described above. An example of the display is shown in Figure 12 or Figure 13.

FIG. 12 displays a list of information regarding the operating status from each control device.

FIG. 13 shows an example in which one of the displayed lists is selected and displayed. The display contents such as display items in the operating state display mode shown in FIG. 12 or 13 are programmed in advance by a tool such as a personal computer, and the settings are displayed in a state written in the image data ROM 52. is mounted on the device 10.

FIG. 14 shows a flowchart in the list display mode shown in FIG. This list display mode is first set by pressing the mode switch key 7 at step 100.
It is determined whether or not 6 has been operated, and the mode switching key 76 is
If YES, the list display mode routine ends. Otherwise, in the case of No, the process proceeds to step 110, and the display items to be displayed, which are set in advance by a program or the like, are confirmed. Subsequently, in step 120, a current value is requested from the control device corresponding to this display item. Next, in step 130, the current value is received from the corresponding control device, and then in step 140
A communication error check is executed under the control of the CPU 32. Next, a communication error is confirmed by the communication error determination in step 150. If Yes, step 12
0, and if no communication error is confirmed, the process proceeds to step 160, where the current value and set value are displayed in the corresponding area of the display section 28. In step 170, it is determined whether the display items to be displayed on one screen are finished.
The process returns to step 110 until this is completed, and then returns to step 100.

For example, when the production number counter 16 measures that the target number of curry breads has been produced and sends out an output signal, the display setting device 10 changes the display shown in FIG. 15 by interrupt processing, for example. Do it automatically.

The contents of the display screen in this case are separately stored in an image data ROM 52 created using a tool such as a personal computer, and installed in the setting display 10. In this way, information transmission between the setting display 10 and the control device (component unit) is always initiated from the setting display 10 side, and the setting display 10 specifies a communication address at the start of communication. The setting values of the control equipment are set through communication from the setting display 10, but since the content of communication varies depending on the type of control equipment, the system RA of the setting display 10
The communication addresses of all control devices and the connection information (format information) of the control devices are registered in M44 in advance. In this case, the connection information may not be registered or a new control device may be added. That is, this is the case when the communication addresses of all the control devices and the connection information of the control devices are not registered in the system RAM 44 of the setting display 10, or when a new control device is added. A case in which the system is operated from such a state will be described below.

FIG. 16 is a flowchart of a control operation for collecting communication address information and connection information of a control device from the control device in the setting display 10.

The setting display 10 can collect only the connection information of the control equipment through communication. Utilizing this, the format information of the control equipment is sequentially read out by polling for all addresses (address range 00 to 15). First, in step 200, the communication address is set to zero, and in step 21
At 0, the control equipment is read. That is, one communication address is designated, and a request for information on the control equipment is executed for that address under the control of the CPU 32 of the setting display 10. In step 220, a response from the control device is determined as to whether or not information about the set control device is stored at the address specified in the communication. If Yes, the CPU 32 proceeds to the next step 230 and stores the connection information and communication address of the control device set at the address specified in the communication in the system RAM 44 in the setting display 10. Executed by control. In the case of No in step 220, where the connection information of the set control device is not stored in the address specified in the communication, it is determined in step 240 that a certain period of time has elapsed. After this certain period of time has elapsed, the designation is determined to be invalid and the next communication address (communication address +
Execute the process that moves to 1). If the predetermined period of time has not elapsed, the process returns to step 220 and waits for a response from the control device. Subsequently, it is determined whether the request for information on all addresses (address range 00 to 15) has been completed. If Yes is completed, it is finished, and N is not completed.
If o, the process returns to step 210 and the above routine is re-executed to complete the request for information in the address range 00-15.

In this way, the setting display 10 moves to a selection screen on the display section 28 of the setting display 10 based on the connection information of the control equipment read into the system RAM 44.
