I can not get my ML1100 to communicate with my honeywell 8010m comms module. I have the PLC set at 9600,n,8,1, with no handshaking. The ch0 driver is set to ModBus RTU Master. The Burner Controller is set to 9600 and slave address 2.

My Message is set for an
1)03 command to read multiple holding regs(the 40001).

2)local Bridge Address is 2 (slave address to be polled)

3)Remote station Address is 0 (not sure what this is yet)

4)remote bridge link ID 0 (not sure what this is yet either)

Yet I still keep getting a time out in the local processor as if there is no response from the honeywell burner controller. I am not sure if there is something else to set in the PLC. If anyone has an example of such code are some input please email me at [email protected]

regards,
Joe

What is a 'Honeywell 8010m comms module'?

Can you provide a link to the communications documentation?

Hi Joe,

You need to change the Control Line in the Channel Config to No Handshaking (RS485 Network) to communicate via Modbus.
