M340 Modbus Plus Proxy

● The M340 Modbus Plus Proxy allows the M340 PLC to communicate with legacy Modbus Plus devices

● It will allow you to update your control system without replacing the existing network infrastructure

● Existing Modbus Plus device applications do not have to be modified to communicate with M340

Key Benefits

● Reduce commissioning time● On-line configuration lets you configure the proxy simply by using your web

browser●Configuration web pages are similar to Concept/Unity Modbus Plus PeerCop & Global data dialogue screens

● Supports Global Data broadcasts to all network nodes for easy data exchange● PeerCop provides point to point communications without programming

● Increase network reliability and maintainability● Standard diagnostics provide data on all nodes in the network for easy

troubleshooting● Dual Modbus Plus ports provide Modbus Plus network redundancy

● Reduce total ownership cost● Enable protection of investment in Modbus Plus while moving to Ethernet● Dual Ethernet ports allow connection of both the M340 and the configuration PC

to the proxy without requiring an additional switch

What’s in the box

● M340 Modbus Plus Proxy module● Mounting plate● Read me first document● Resource CD

● M340 User Guide

● M340 EGD configuration management utility

● Backup Proxy configuration file

● Restore Proxy configuration from a file

● Generate CSV file of Proxy’s configuration

Web configuration

● Configure the module using a simple web browser interface

● Configuration web pages are similar to Concept/Unity Modbus Plus PeerCop & Global data dialogue screens

● Each page has a help button to assist in configuring the Proxy’s parameters

Global Data support

● The Proxy lets you configure global data in the Modbus Plus network● It enables cyclic broadcast exchanges of global data between

participating nodes● The Proxy can broadcast up to 32 words when a node rotates the

PeerCop Specific support

● The Proxy lets you configure PeerCop Specific in the Modbus Plus network

● Cyclic Specific inputs and outputs act as a point-to-point-service ● Every message contains one or more receive addresses for

transferring data (enables data to be forwarded to several stations without repetition)

M340 offset functions

● Offsets redirect 1x and 3x data from Modbus Plus to M340 PLC● Offsets only apply to functions such as MSTR, SCADA and HMI● Default values will not conflict with converted legacy applications

● Default 1x = %M2048, Default 3x = %MW2048

● Default PeerCop & Global Data Health write 12 words to %MW3072 in M340 PLC

Legacy offset

● Legacy offsets address all functions including PeerCop & Global Data legacy compatibility by adding 1 to accommodate for the difference in the starting register location in the M340 PLC when using a converted application.

● Starting register in M340 PLC is %M0 and %MW0● Legacy offset redirects 100001 to %M1● Legacy offset redirects 400001 requests to %MW1

M340 EGD routing on Modbus Plus

● Supports 5 byte routing on Modbus Plus using Read_Var & Write_Var● Point Read_Var to index and enter routing information

Diagnostics capability

● Provides Modbus Plus network statistics which includes:● Address and status information for the M340 EGD in its role

as a node on the Modbus Plus network

● A count of detected Modbus Plus errors

● A list of active nodes on the Modbus Plus network

Configuration management utility

● Windows application to:● Backup Proxy configuration to a file on your PC

● Restore Proxy configuration from a file

● Generate an Excel report showing only configured values

Upgrading proxy firmware

● Use Unity Loader to update proxy firmware● Same as for M340 PLC

● Unity Loader v2.0 or higher
