I'm using a Automation Direct DO-O5DR PLC with a DO-DCM 2 port comms card. All I am doing is displaying the high speed input count on the screen. There are a couple more lines in the program but this is basically it. I keep getting a "PLC-001LC communications timeout" error. It is only the displays on the comm card that are doing this. I have it configured for RS 232 communications. I changed the baud from 9600 t0 32400 and it seemed to help. Sometimes when I have the error it will not update the screen for a few seconds. Is there anything I can do about this or is it a limitation I will have to live with? Right now I have everything setup on the bench. They will be within 50' of the PLC but is this something that may get worse with distance
