Emerson Ethernet I/O Card (EIOC) Supported Industrial Ethernet Protocols

be used to allow the connection into the PRP network without

having bad status in diagnostics.

EIOC Configuration

The EIOC is configured in the I/O network level of DeltaV

Explorer and it does not count towards the controller node

count limit (limited to 60 EIOCs per system). The hierarchy

of the EIOC in DeltaV Explorer consist of:

„ EIOC

z Assigned Modules – Modules configured and running

inside the EIOC.

z Hardware Alarms – Hardware alarms associated with

the EIOC.

z PO1 – EIOC port, where the Ethernet Device Network

and protocol is setup.

z PDT – The Ethernet Devices are added and configured

under the EIOC port as Physical Devices (PDTs).

The amounts of PDTs that can be configured will vary

depending of the protocol selected in the port and

the amount of device licenses assigned. The PDTs can

be renamed.

z LDT – Logical Devices (LDTs) are added under the PDTs to

configure signals or control tags depending of the protocol

that has been selected at the port level. DST licenses are

applied at this level.

EIOC Licensing

Licensing for the EIOC is easy and scalable. Just buy the

hardware assembly for the EIOC, simplex or redundant.

No additional license is required for redundancy. Then decide

which protocol you need (one per EIOC is permitted),

and pick the appropriate license. Next, determine how many

Ethernet Devices you need to connect, and pick the license

containing the required number. Once the EIOC is configured

one DST license will be consumed per LDT, with the type being

determined based on the highest value configured in the LDT

(except for the EtherNet/IP Control Tag Integration Protocol).

For the EtherNet/IP Control Tag Integration protocol,

one DST license is consumed per Control Tag. The DST license is

consumed based on the type of Control Tag that is configured.

PRP does not require a license, as it is included as part of the

EIOC functionality.

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.
