Distributed Equipment

Distributed equipment can be connected to an M580 system in the following ways:

  • a DIO daisy chain

  • a DIO daisy chain loop

NOTE: DIO daisy chains and DIO daisy chain loops are described elsewhere in this guide.

Distributed devices in a loop have two Ethernet ports (to maintain the ring), and they support RSTP. An example of equipment on a DIO loop would be several STB islands that use STB NIP 2311 NIMs.

Ethernet distributed equipment that can be put on distributed device clouds include these families of devices:

I/O Scanned Equipment

Equipment that Cannot be I/O Scanned

Altivar variable speed drives (ATV32, ATV61, ATV71, ATV6••, ATV9••)

Magelis HMI controllers

main protection and control functions (TeSys T)

Pelco cameras

ETB (I/O modules), OTB (DIO modules), and STB (modules connected on a single island)

 

remote master interfaces (Profibus, CANopen, ETG1000, Hart)

EtherNet/IP adapter devices
