Hello!
I'm also facing some problems with Modbus communication over a Omron CP1W-CIF11 Port that I have hardwired on the right side of a CP1E PLC. Attached you will find a simple test program that I have done form testing the communication with a Danfoss Drive. I only want to 2 read registers but I keep receiving the 80 Hex error. Any ideas what is wrong on the program?
Thanks in advance,
Bruno
