Application

Ethernet communication gateway between ABB AC800M DCS and third-party devices:

1. Power plant boiler & turbine control system, communication with smart instruments and VFDs
2. DCS system for oil & chemical plants, connect flow meters and pressure transmitters
3. Metallurgy & paper mill production lines, data exchange with drives and third-party PLCs
4. Water treatment and cement plant process control
5. Automation systems for ships and offshore platforms Function: Act as Ethernet gateway for AC800M controller, collect data and send control commands to field devices over Modbus TCP. Redundant design improves link reliability. Hot-swap maintenance avoids system outage and enables interconnection of multi-brand automation equipment.
