glaverty Posted September 27, 2006 Report Posted September 27, 2006 How are you connecting the 9030 to the computer that you are running the OPC Server on? Are using the programming cable? Quote
ciwa Posted September 27, 2006 Author Report Posted September 27, 2006 Yes, i use programming cable with rs-485 converter. Quote
RussB Posted September 28, 2006 Report Posted September 28, 2006 If you are plugged into the port with the blinking LED I suspect that you either have an incorrect parameter: baud, parity, etc. or maybe the wrong CPU ID. Quote
