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

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
token

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
