Distributed Equipment
Distributed equipment can be connected to an M580 system in the following ways:
a DIO daisy chain
a DIO daisy chain loop
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 |
