Summary

The EIOC supports communications with Ethernet Devices

using Modbus TCP, EtherNet/IP, IEC61850 MMS, OPC UA client

and Ethernet/IP Control Tag Integration protocols. The EIOC

supports a huge capacity of data for monitoring or control.

The Capacity, polling and switchover times vary based on

protocol, device type, and loading. Refer to the DeltaV System

Planning Guide for more information.

The EIOC capacity lends itself to very large integration projects

with limited control needs. For applications that require

batch or sequence control (class-based units, PLMs, SFCs,

and Equipment Modules are not supported in the EIOC)

or more complex control that requires other functionality

such as traditional, bus, or Electronic Marshalling IO, then a

PK controller or a VIM2 card combined with a DeltaV controller

could be a better solution. Please consult your local Emerson

office for more details.
