My system has an Allen Bradley PLC, Red Lion CR3000 HMI, and a Watlow F4T controller.
I am able to read registers from the Watlow F4T via Modbus TCP and the Red Lion is being used as a gateway to get the information into the CIP protocol to get the data to the PLC. I can read registers in the Watlow and send them to the PLC but when I try to write from the PLC to the Watlow it doesnt work.
Has anyone had an issue writing to the F4T?
In the Red Lion I talked with technical support and disabled the 06 function and left the 16 function enabled.
