Shared remote I/O for maximum flexibility

I/O Targeting. The M-series Zone 2 Remote I/O Units supports

targeting of Classic I/O to controllers on a per card basis.

For example, a card can be owned by a controller, with different

I/O cards owned by a different controller, with the limit that a

Remote I/O Unit can support 4 controllers maximum.

Each DeltaV controller can have up to 16 Remote I/O Units

associated with it.

The DeltaV system supports up to 300 remote I/O Units1

and they communicate on the same Ethernet network as

the controllers and workstations.

The RIU2 supports 10/100MB communication on both primary

and secondary ports.

Data Passthrough. The controller is equipped with the

ability to pass smart HART® information from field devices

connected to a Remote I/O Unit to any workstation node

in the control network.
