I have been trying to link a Mitsubishi FX-24MR PLC to the National Instruments Lookout SCADA software using the FX-485ADP and FX-485PC-IF modules, with no success. I'm sure that I have wired the serial cable correctly, as the RD light is blinking on the PLC comms module - the PLC never sends any data back however, and all I get is timeout errros. Can anybody help?
