8521-LC-MT Ethernet bus interface module

Description

The MOST Ethernet Bus Interface Module
(EBIM) is a rugged, field-mountable platform intended for remote I/O mounting in
harsh and hazardous process applications.
The Ethernet BIM supports full redundant
operation, with provisions for redundant
communications and automatic switchover
to the standby EBIM if required. The EBIM
supports a HART pass-through capability,
which can be used for remote maintenance
of HART field devices.
Overview
The EBIM can be used in two communications modes: with MODBUS TCP as remote
I/O to another host system, or with highspeed peer to peer communications as
remote I/O in a MOST Control system.
When using MODBUS TCP, the EBIM acts
as a slave, communicating over Ethernet in
RTU mode at speeds of 10/100MB.
Combined with the MTL 8000 Process
I/OTM system components, it offers cost savings over control-room mounted systems as
well as flexible system design and high system availability. An EBIM can utilize off-theshelf HMI packages, including
Wonderware, Intellution and Cimplicity.
In a MOST Control system, an EBIM system
can be used as remote I/O node to a
MOST system Controller. When used in a
MOST Control system, all remote EBIM
nodes are configured as if part of a local
I/O system, providing a single integrated
configuration of all I/O nodes in the system,
whether local or remote. Data is passed
efficiently to the controller from the EBIM
using high-speed peer to peer communications.
Applications
The remote-mounted EBIM node is an ideal
solution for all types of process applications, including the following industries:
chemicals, petrochemicals, water and
waste water, oil and gas (especially offshore applications), pipeline, power generation, electrical distribution, food and beverage, cement and pulp and paper.
Benefits
Reduced cable costs
Instrumentation cable pairs terminate locally instead of being run across the plant to
the control room. Heavy, expensive sensor
cables are replaced by the LAN cable.
Reduced termination costs
Field wiring goes directly to the I/O terminals in the local field enclosure – no addition-al cross wiring to marshalling panels
