„ Easy to use. The EIOC is easy to use as it provides a native

way to bring Ethernet protocol data into the DeltaV system.

Specific ease of use features include:

• You can choose between the 5 different Ethernet

protocols supported in the EIOC. Only one protocol is

supported at a time and requires the proper licensing.

• Updates for the EIOC and drivers are included

within DeltaV.

• Configured in DeltaV Explorer. All needed configuration

for the Ethernet Devices is done in DeltaV Explorer and

DeltaV Control Studio, just like Traditional I/O signals.

The data can be configured in DeltaV Control Modules,

displayed on DeltaV Live and DeltaV Operate graphics,

and stored in the DeltaV Continuous Historian.

„ Modular and Easy to add Redundancy. The dual horizontal

carrier hosts all the needed components for a redundant

setup (redundant Power input Terminals and redundant

Ethernet Isolation ports). The EIOC becomes redundant

just by adding a second EIOC on the dual horizontal

carrier. The configuration will change automatically,

confirming that the two EIOCs are now working as a

redundant pair. Manual switchovers can be controlled

in DeltaV Diagnostics Explorer. The redundant Ethernet

ports provide isolation between DeltaV Control Network

communication and the redundant Ethernet Device Network.

The EIOC also implements Parallel Redundant Protocol

(PRP) for an added layer of robustness, providing a seamless

switchover between primary and secondary networks.

„ Huge processing capacity. Each EIOC is capable of handling

a huge amount of Data in up to 2000 Control Modules.

„ EIOC is part of the DeltaV Control Network. 60 EIOC’s

can be added directly to the DeltaV Control Network,

allowing maximum freedom in segregating your networks.

„ Flexible networking. User configurable IP addressing for

the Ethernet Device Network allows the EIOC to be used in

almost any plant environment regardless of the networking

scheme. When designing a simplex Ethernet Device Network,

consider that the EIOC and the Ethernet Devices must be on

the same IP subnet to communicate. Also, when designing

a redundant Ethernet Device Network, consider that the

primary and secondary ports in the EIOC must be in different

subnets to follow best engineering practices.

Benefits

Ability to communicate directly to Ethernet Device

Networks. Use the EIOC to monitor and control

Ethernet Devices.

„ Powerful and Scalable. The EIOC allows a huge amount of

data coming from Ethernet Devices to be accessed in DeltaV,

and is scalable to fit your needs with licensing based on the

number of devices you connect. The EIOC can bring:

• Up to 32,000 signals from 256 Ethernet Devices when

using Modbus TCP, EtherNet/IP, or IEC61850 MMS.

• Up to 30,000 signals from 64 Ethernet Devices when

using OPC UA client protocol.

• Up to 2000 tags (10 signals per tag) from 256 Ethernet

Devices when using EtherNet/IP Control Tag

Integration Protocol.

„ Monitoring. Data values integrated into the EIOC can

be used in Control Modules running inside the EIOC.

These control modules allow alarm generation,

history collection, and viewing by the operator,

as with control modules running in a Controller

using traditional DeltaV native I/O.

„ Supports control functionality. In addition,

function blocks allowing for discrete control and limited

PID control are supported for the EIOC. No assignment to a

controller is required. Motors, switchgear, variable frequency

drives; or any device that communicate via Ethernet

protocols can be controlled directly from the EIOC.

„ Easy to connect to Ethernet Devices using Modbus TCP,

EtherNet/IP, IEC61850 MMS, OPC UA client and EtherNet/

IP Control Tag Integration protocols. Use the EIOC Ethernet

protocols to connect your DeltaV system to your Ethernet

Device Networks.
