Bristol Babcock RTUs interfacing with ABB VFDs using MODBUS


Thread Starter

Robert Dusza

To everyone,

Thanks in advance for reading this.

We are trying to setup our VFDs to talk to our BBI RTUs using MODBUS protocol and BBI is not real happy with trying to work it out. Does anyone have any experience with this equipment in this configuration. We are trying to move to electronic control of our VFDs and other equipment. The VFDs are ABB ACS400 units and the RTUs are 3330s and 3305s.

Bob - Did you ever solve that BBI to ABB interface problem? I've interfaced BBI products to other devices using modbus...seems to work okay. SMH
