Features and Benefits

GE Fanuc Automation and GE Drive Systems developed an Ethernet

Global Data, or EGD, exchange for PLC and computer data in 1998.

Ethernet Global Data (EGD) offers versatility where a mix of control

devices requires cooperation with each other. This involves sharing

of information across the applications regardless of device or network

type, often at high speed, and with high reliability. High reliability

means fewer communication failures and having the ability to detect

failures upon occurrence. Particular emphasis is delivered for

applications requiring periodic or frequent updates and time

synchronization of devices. The protocol supports Unicast, Broadcast

and Multicast group messaging. Efficiency is based on the fact each

device on the network can produce these types of messages and

each device determines which of these messages to consume.

MVI56-EGD

The Ethernet Global Data (EGD) module can be used to interface

many different protocols with EGD devices. The EGD driver supports

both the producer/consumer service port (18246) and the command

service port (7937) using the UDP protocol over an IP network. The

user defines the data to be produced and consumed in a

configuration file downloaded to the module.

The MVI56 Limitorque Valve Actuator Master Communication Module allows

ControlLogix compatible processors to interface easily with Limitorque Valve

Actuators and other Limitorque protocol compatible devices.

The MVI56-LTQ module acts as an input/output module between the Limitorque

valve network and the ControlLogix processor. The data transfer from the

ControlLogix processor is asynchronous from the actions on the network. The

1500-word register space in the module transfers the valve information from the

module to the processor. Ladder logic is responsible for control of the valves.

Data transferred from the processor to the module instructs the module to

execute commands to valves on the Limitorque network.

Features

 Meter Runs: The module can calculate up to 16 meter runs simultaneously

with a maximum of 16 streams on a single meter run

(64 streams maximum per module shared among all 16-meter runs).

This flexibility provides a cost-effective, highly scalable solution for all your

measurement applications.

 Modbus® Capabilities: Remote configuration and diagnostics via Ethernet

(Modbus TCP/IP) or Serial (Modbus) interfaces.

Flexible serial port configurations allow for either two Modbus slave ports or

one Modbus slave and one Modbus Master port. All

data, including configuration, calculated results, and historical archives, are

available using either the Modbus TCP/IP server or Modbus slave serial ports.

 Customized Modbus Data Mapping: Remapping to a virtual slave enables

data concentration, reducing bandwidth load on the communication system.

 Auditability: Our configuration software provides the ability to download

and view archives and events. Audit Scan captures process inputs and

calculated results as “snapshots”, allowing verification of calculations.

The Log files record significant events and alarms. Hourly and daily archives

are configurable historical records of user-selected data. 

The data can be viewed online, printed, or saved to a file in .txt or .csv format.

Archive data can be exported to Flow-Cal .cfx format. Meter calibration and

verification are stored on the module.

 Meter Proving: Allows for meter proving with 3 configurable prover types.

 Security: Password protection schemes are available to control user access

and log meter calibration and verification activities.

A built-in web server allows local/remote configuration, monitoring, and wireless

network diagnostics.

ProSoft Technology’s MVI56E-AFC in-chassis flow computer solution allows you

to combine the power and scalability of a ControlLogix® automation system with

the functionality typically only seen in a stand-alone flow computers or dedicated

measurement RTU’s. This provides you with the industry standard calculations,

archiving, and reporting needed for custody transfer and allocation-based

measurement functions for Oil and Gas operations.

By combining automation and measurement functions into a single solution, this

helps to reduce overall support and integration costs for Oil and Gas

applications while also decreasing your overall capital spend. This simplified

solution allows you to optimize your resources.

In addition, because our flow computer sits in a ControlLogix system, you can

take advantage of Rockwell Automation’s distributed I/O capability, wide range

of communications protocols, and ProSoft’s wireless radios to greatly reduce

wiring to your transmitters and I/O devices.

Since the module operates as a co-processor for measurement related functions

to the ControlLogix system, and as measurement requirements of the site grow,

you can simply add an additional MVI56E-AFC module to increase your

measurement capabilities to an individual site. A truly scalable automation and

measurement solution.

Features

♦ AOP and AOI: Module communication is integrated within Studio/RSLogix™

5000 using a sample Add-On Instruction (AOI), and

custom configuration utility created Add-On Routines to reduce commissioning

time.

♦ Autoscan: The Autoscan feature reduces startup times and simplifies

troubleshooting by scanning the PROFIBUS network and

uploading slave device addresses and configuration information. (Reads and

maps nodes automatically to the module.)

♦ ComDTM: Allows remote Ethernet connectivity with Asset Management Software,

significantly lowering maintenance costs.

You can configure, commission, maintain and diagnose your fieldbus devices

throughout their entire lifecycle with this

comprehensive, fully integrated engineering and maintenance environment.

♦ SD card slot (SD card optional) is used for storing configuration files in the

event of a disaster.

♦ Redundancy: Two modules can be used along with the custom Add-On Routine

to allow for a redundant PROFIBUS DP network for high availability systems.

The ILX56-PBM PROFIBUS DPV1 Master/Multi-Slave module allows

Rockwell Automation® ControlLogix® processors to communicate with

various PLCs and devices using the PROFIBUS DP protocol.  As a

PROFIBUS DP Master, the module can transfer up to 5000 bytes of

cyclic I/O data with various slave devices on the network.

Or you can use the module as a PROFIBUS DP multi-slave, where the

module can emulate up to 10 individual nodes on a PROFIBUS DP

network, allowing for more cyclic I/O data transfer.

With the ILX56-PBM module, ControlLogix® processors can easily

communicate with devices supporting PROFIBUS DPV0 and DPV1

protocol. And through premier integration tools such as a custom Add-On

Profile, project-specific Add-On Routines, and advanced tools such as

PROFIBUS DP packet capture utility, you can minimize the time required

to get a PROFIBUS DP network configured in a ControlLogix®

environment.

In addition, with the use of multiple I/O connections back to the

ControlLogix® processor, this module provides data update rates that will

meet even the most demanding applications.
