Hi at the end of the working day I had some luck with my problem: my RxD light strted to work. The problem was that I connected RS line to the wrong pair of wires. I hade original cable with two 9pin connectors at the cable ends, I disasambled one connector and checked whitch wires are connected to the pins four and eleven, but the problem was that I was using the other side connector for communication and the wires in the other side was connected in other order, so it was my mistke... But, I still have no modbus answer from CP. The most strange thing is this, that I'm getting answer frame with error code 82 only then, when I put CPU in STOP mode, so I can see, that HW settings are correct (Slave ID, baudrate, parity...). When the CPU is in RUN mode, then I got no answer from CP341 (timeout error). And now I have an error on the diagnostics buffer. Info is in the added file. As fr as I understand, I need somthing in my program, but stil can not find out, what... BR Audrius
