Hi all,
I have been having a frustrating time communicating between my esmart04 HMI and my Productivity P1-540 PLC.
Currently, I am simply just trying to see any sort of communication between them using some simple read/write commands.
I have attached images to show my settings.
I have done RS-485 comms on the Exor before and have not had any issues.
I even copied a setup where this works to my setup and it did not work.
My DB9 wiring is pin 7/8 -> TX/RX+ 3/4-> TX/RX- and 1 -> Gnd
I am at my wit's end here. Any advice or suggestions would be amazing.
I can provide any more info as needed.
Thank you.
