IEC 61850 (MMS)

The IEC 61850 MMS interface will allow data from Intelligent

Electronic Devices (IEDs) such as motor protection relays,

motor starters, motor control centers, switchgear, and similar

MMS-based devices to be integrated into DeltaV. The MMS

interface will be a client reading and writing data from/to the

Intelligent Electronic Device which acts as the server.

The EIOC only supports reading and writing of real time

signals using this protocol. Reading historical data or

Goose applications are not supported.

OPC UA Client

The OPC UA Client in the EIOC provides native client

implementation of a Data Access profile (real time data)

compliant with OPC UA version 1.03. The OPC UA client will

read and write up to 30,000 real time signals coming from

up to 64 OPC UA servers.

EtherNet/IP Control Tag Integration protocol

The EtherNet/IP Control Tag Integration protocol utilizes

EtherNet/IP Class 3 messaging to provide integration with

tag-based PLC data sources. Referencing data by tag name

eliminates the need for register mapping. Read or write up

to 10 signals per tag, and up to 2000 tags per EIOC for a total

of 20,000 signals. The EtherNet/IP Control Tag Integration

protocol supports reading string type signals and read/write

of arrays up to 64 elements each (max 100 arrays per EIOC).

The EtherNet/IP Control Tag Integration protocol supports

integration with ControlLogix and CompactLogix PLCs utilizing tags.
