Supported Industrial

Ethernet Protocols:

Modbus TCP Interface

The Modbus TCP interface will support Modbus data

sources such as PLCs, MCCs, analyzers and similar devices

communicating Modbus TCP. The Modbus TCP interface is a

Modbus Client reading and writing data from/to Modbus Server

devices. The Modbus server devices can be Modbus TCP devices

or Modbus serial devices using a Modbus TCP gateway.

The Modbus TCP interface supports the following types of

data access:

„ Reading input data from Modbus Coils, Discrete Input,

Holding Registers, and Input Registers.

„ Writing output data to Coils and Holding registers.

All reads will be performed periodically and outputs will be

sent when they are written.

EtherNet /IP

The EtherNet/IP protocol allows data sources such as

PLCs, Intelligent Field Devices (IFDs), variable-speed drives,

MCCs, and analyzers; as well as other devices communicating

EtherNet/IP to connect directly in to DeltaV via the EIOC.

The EtherNet/IP interface will support connections for

both implicit and explicit messaging to allow access to both

Class 1 and Class 3 EtherNet/IP I/O adapters. Redundancy with

EtherNet/IP Class 1 Implicit and Class 3 Explicit messaging

for control (sending outputs to the devices) require special

considerations due to exclusive owner communications defined

by the protocol. Please refer to the DeltaV System Planning

Guide for more information. Class 3 PCCC and UCMM with

www.abb-drive.com Logix tags message classes are also supported.

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.
