GE 8851-LC-MT

Description

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.
Integrated IS capability mixed with generalpurpose signals, together with integral tagging and fusing options, dramatically
reduce engineering and design costs.
Flexible system design
Combine analog and discrete modules for
maximum flexibility and use of space.
High system availability-easy maintenance
Maximize up-time by incorporating redundant EBIMs, power supplies and net-work
connections. ‘Hot swap’ modules, without
affecting system operation or reconfiguring,
even in hazardous areas.
On-line changes
The EBIM allows on-line configuration
changes during testing, start-up, and maintenance phases. This significantly accelerates system start-up and reduces operation
downtime.
The Ethernet BIM platform
The Ethernet BIM incorporates a rigorous
redundancy model, HART® capability and
a fault tolerant Ethernet implementation to
manage communications on the process
network and deliver reliable system operation in your application. Process I/O™ is a
field-mounted distributed I/O system that
provides an intelligent interface between
field-mounted instrumentation and the Host
system. Process I/O™ interfaces to virtually
all process signals including HART®, providing a complete solution for your I/O
needs. The complete platform has an environmental specification capable of surviving conditions out in the plant. It is built for
harsh process applications, being shock
and vibration resistant, operating over the
industrial -40°C to +70°C temperature
range that is typically associated with field
transmitters, and meeting ISA’s stringent G3
corrosion resistance requirements. The
EBIM and I/O components can all be
mounted directly in Division 2/Zone 2 hazardous areas and, when required, can provide a cost effective intrinsic safety solution.
Because the system can be mounted in the
field, it can also provide extensive cost savings by eliminating the need to wire all sensors back to a central controller. With the
EBIM and its I/O mounted in the field, the
only wiring back to a control room is the
high-speed network.
Redundancy
Redundant EBIMs can be used for critical
applications. The master/standby pair
operate in a rendezvous redundancy mode
with frequent status checks to assure a rapid
and bumpless transfer to the standby if
required. The redundancy model supports
on-line configuration and on-line firmware
changes, where any updates are shared
between controllers in real-time, resulting in
an easy to use redundant system.
The EBIM also supports LAN redundancy. A
fully redundant local area network (LAN)
can be provided where each EBIM has two
independent Ethernet ports connected to
two separate independent networks. The
EBIMs monitor the networks’ health and will
switch between networks when they detect
a problem.
Redundant power supplies are available to
provide power for critical applications that
must not shut down if a power supply malfunctions.
Peer to peer communications
The EBIMs can communicate with MOST
Controllers on a peer-to-peer basis, removing the need for all data to be passed
through the control room.
