I've read a bunch of the post on here as far as communicating between the ML1400 Channel 0 and the Powerflex 400 via RS485. I cannot for the life of me get it to work properly. I am using the 1763-NC01 connector. Right now I have A/B connected to pins 4/5 on the RJ45. I have tried swapping, and think I have the right config as when I swap one way, the Port LED flashes red, and clears to Green the opposite config. I have channel 0 in the PLC set up correctly as No Handshaking (485) and I get no response when sending a msg. I have confirmed comms rate & node address.
Terminal 20 on the VFD is connected to ground... and I missing something on the NC01? I have tried with a jumper in COM to CGND and without.
Thanks for any advice.
