Ethernet I/O Card

The Ethernet I/O Card (EIOC) provides an interface to Ethernet device networks and to intelligent devices that use the Modbus TCP/IP, Ethernet/Industrial Protocol (EIP), or IEC 61850 Manufacturing Message Specification (MMS) protocols. The EIOC accesses intelligent device data for history collection, alarming, and limited control. Control modules running in the EIOC make the device data available to the DeltaV system.

The EIOC is not a DeltaV controller. Unlike a DeltaV controller, the EIOC supports a subset of function blocks that are used for motor control and supervisory control and references device data only. It does not reference other I/O such as CHARMs I/O. The EIOC only references data from devices on the network to which it is connected. It does not support externally referenced data.
