mikeexplorer (Customer) asked a question.
I plan to add a second HMI screen to an existing Click PLC. The HMI will be located some distance from the PLC so I would like to use COM port 3 (RS485) to communicate with the HMI
Can this be done and what settings would the Cmore need to communicate?
Port 3 is the 3 terminal RS485 port. The screen shot you posted shows it as a diferent port.
The Click is a C0-01AR-D I plan to use a Cmore CM5 T4W. It will be located about 50 to 75 feet away from the PLC so that is why I wanted to use the Port3 on the Click (the 3 pin RS485) Port 2 already has a EA1 3 inch monochrome HMI.
OK thanks for the details. You will use Port 1 on the CM5 for RS485. Refer to CM501 for details on setting up serial comms with a Click CPU.
Ok thank you for the information. Looking in the CM5 user manual. This should be the cable I need to make up. I do not need the "EA-COMCON-3" ?? Or do I need it?
It appears this device would make wiring easier since I plan to run a long cable that is rated for RS485 communications (Q8302-1)
If not needed or will not work for this application, I can solder a 15 pin connector.
Yes you can use the EA-COMCON-3 with the 4 inch CM5. Like you mentioned it makes the wiring easier than having to create your own 15 pin connector.
OK thanks for the details. You will use Port 1 on the CM5 for RS485. Refer to CM501 for details on setting up serial comms with a Click CPU.
