Hi,
I am trying to get Allen Bradley Micrologix 1400 to send ASCII commands over a RS-485 2 wire connection. I can get PuTTy to communicate just fine. The communication settings are
Channel 0
Modbus RTU Master
Baud 19200
Parity None
Stop bits 1
data bits 8
No handshake (485 network)
I have the 1763-NC01 (aka the RS-485 connverter) plugged into channel 0. I have A and B wired to the other device. I am using the AWT command. I have The ST10:0-ST13:0 with the commands in them and using R14:0-R17:0 for control. The AWTs send all of the characters with no errors.
I have tried switching the A & B wires to no effect. I am stuck and out of ideas to try. Any suggestions?
