The EIOC is a big pipe for the integration of process data from

3rd party Ethernet Devices, such as PLCs and smart field devices

such as Intelligent Field Devices (IFDs) and Intelligent Electronic

Devices (IEDs). A network of these Ethernet Devices can be

directly connected to the EIOC. The Ethernet Devices can

communicate to the EIOC using one of five protocols;

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

and EtherNet/IP Control Tag Integration. The EIOC connects

directly into the DeltaV Control Network and can be placed

remotely in an enclosure in the field.

The EIOC is an independent embedded data server. This means

that there is no need for a separate controller to process the

data being integrated into the EIOC. Control Modules needed

to process the data from the Ethernet Devices are assigned and

executed in the EIOC. In this way, communications with the

devices are fast and direct. Any parameters from the modules

running in the EIOC can be read by both S-series and M-series

controllers using External References when needed in control

strategies at the controller level.

Access to DeltaV Live graphics, DeltaV Operate graphics, and

the alarms and history collection from EIOC control modules

follows the same rules and mechanisms as control modules

running in the controllers in a DeltaV System.

The EIOC mounts on the dual horizontal carrier, which includes

redundant Power input Terminals as well as redundant

Ethernet Isolation ports. The Ethernet Isolation ports isolate

the redundant DeltaV Control Network communication

from the redundant Ethernet Device Networks. An Industrial

Networks Firewall is recommended to provide added security

based on deep packet inspection to restrict communications

at the Ethernet device and Ethernet protocol level. In this way,

Robustness and Security is ensured.
