I want to let the PLC communicate with the Delta touch screen now, but I can’t communicate with any settings. The touch screen model is: DOP-B10S411. The PLC model is; FX3U-64MT. The touch screen communication parameters are set in this way: man-machine station number: 0 communication interface: RS232 data bit:
1, PLC does not need to be set
2. The communication protocol is set in the Delta touch screen (RS-422, 9600, E, 8, 1)
3, RS-422 communication line is connected, you can power on
