If there is a discrepancy between the contents of the display screen of the programmable controller (8) and the contents of the display screen of the programmable controller (8), a message indicating the fault location and the number of discrepancies will be displayed.

As mentioned above, programming device with CRT (4)
The contents of the monitoring screen programmed in are stored in the control unit 491 of the programmable controller with CRT (8), and the programming device iiK (not shown)
Is the programmed sequence stored in the programmable controller (])? in a state that

Programmable controller il+ and control i+9+
When the programmable controller with CRT (81) is activated, the programmable controller with CRT (81) performs control, operation, and monitoring functions for the control@machine (31).

Figure 1 shows programmable controller with CRT (8)
FIG. 8 shows the key arrangement of the keyboard 0υ. When the programmable controller (1) is activated, the 1 indicator light ``programmable controller operation'' lights up, so select the operation mode with the operation mode changeover switch, and select the route with the route selection switch. If the lamp display circuit shown in Figure 6 is registered, use the A-) selection switch to route 0.
When the KF-1 is selected, the display circuit for route 0 is displayed on the screen of ITO (I) as shown in Fig. 9, and when route 1 is selected, the display circuit for route 1 is displayed as shown in Fig. 10. If you select a route that is not registered, the registered lamp display circuit will be displayed as shown in Figure 6. At the same time, the device name setting area will display the device name. is displayed, and the registered route selection device ID and registered route selection device are displayed in the route selection area.When the route selection is completed after checking all driving modes, the control unit (9) and the programmable controller (1) By communicating with each other, you can check the on/off status of each selected root device.
The status is displayed on the screen of cFITO(I) as shown in FIG.

When the operation mode is step or individual operation.

There is a forced output function that forcibly turns on and off the output (Y) and temporary memory (B) of the programmable controller i11 using the key switch of the keyboard 0υ. Since the input (XJ) cannot be forcibly output, it is skipped and the next device symbol is forced to output the device in the output (YJ or temporary memory (b)).

The operation method for forced output is as follows. When you select the device name using the number keys,
The selected device name is displayed in the lower right corner of the CRT screen.

(C) Press the ``operation command selection'' key and then input the device number using the numeric keys 0 to 9.

(ω By pressing the “ON” key, the device corresponding to the selected device is forcibly turned on.

However, if the nine selected devices are not registered in the selected route, an error message will be displayed.

(e) When the operation mode is step operation in %.

By continuing to press the 'ON' key, forced output can be performed continuously, and the name of the device that was forced to output after forging is displayed in the lower right corner of one screen.

(Press f'J'OFF' key to turn off all devices that were turned on with forced output.

When a failure or operational problem occurs in the controlled machine, the external failure device (F) of the programmable controller (])
Since J is turned on, the control section 19+ knows that the external faulty device is an external faulty device by communicating with the programmable controller (1), and displays the registered fault display contents in the message area of the CRTOG. In addition, when a failure occurs, a buzzer (not shown) sounds to alert the operator. The buzzer is stopped by pressing the 'stop buzzer' key on the keyboard ALL.

As described above, according to the present invention, a programmable controller, a CRT, operation switches, and a keyboard are provided, and control, operation, and monitoring functions are integrated, and a monitoring screen can be created arbitrarily using a programming device with a CRT. Furthermore, since the operation surface has been designed so that any operation can be performed without any change, the device can be made compact and a controller with flexibility and ease of maintenance can be obtained. There is.
