Hi Folks,
I have a Micrologix 1500 Series C rev 9 with a 1761-net-AIC connected to a weight transmitter. Communicating via Modbus RTU as Master.
Everything is working perfectly when connected to Channel 0 (I can use either PM02 or AM00 and both work fine). For hookup and HMI reasons, I need to get the Modbus connected to Channel 1, and I simply cannot figure out why it will not connect.
On the Logix500 side for CH1, I have the baud rate set matching the device (19200), The Driver set for Modbus RTU Master, No Handshaking, and I have only one simple MSG instruction running (on a 2 second timer) and it has the proper controller (Channel 1 Integral) and slave node address(2) set on both ends.
When trying to connect to the Micrologix, I've tried both a PM02 and a serial cable. I get one bleep on the TX of the AIC and thats it.
Anyone see anything missing?
