Communication

The RIO600 supports fast real-time horizontal GOOSE communication in accordance

with the IEC 61850 1st and 2nd edition standards for substation automation.

The RIO600 also supports Modbus TCP communication with a Modbus TCP client.

Both can be used in parallel in the same Ethernet bus.

The RIO600 sends and receives binary signals to and from ABB Relion®

protective relays and station automation units.

The RIO600 sends and receives binary signals between

 the protective relay and the station automation unit COM600.

The RIO600 subscribes to signals from five devices and publishes signals

to multiple devices depending on the user configuration.

Using the same Ethernet port, the RIO600 can be connected in parallel to

the PCM600 and the web browser via the same communication bus.
