2/26 Presentation Modicon M340 automation platform Modbus Plus Proxy module Presentation The TCSEGDB23F24FA Modbus Plus Proxy module is a network gateway that allows Modicon M340 and M580 PLCs to communicate with existing Modbus Plus devices. It is not necessary to modify the applications for these devices to communicate with the Modicon M340 and M580 PLCs, since the module automatically addresses the platforms and the various communication functions between the M340/M580 and other PLC platforms (especially 984LL). The Modbus Plus Proxy offers Modbus Plus PLC users the chance to integrate the M340 and M580 PLCs easily into their Modbus Plus network and thus to access advanced communications via Ethernet, or to migrate gradually from other PLC models to Modicon M340/M580 and Unity. Key benefits Reduced startup time b Online configuration of the proxy via a simple Web browser b Setup Web pages similar to the screens of the Modbus Plus Peer Cop utility, accessible under Concept/Unity for the Global Data transaction b Simpler data exchange with Global Data transactions performed on all network nodes b Point-to-point communication without programming with Peer Cop Increased network reliability and maintainability b Standard diagnostics provide data on all network nodes for easy troubleshooting b Dual Modbus Plus ports provide Modbus Plus network redundancy Reduced total cost of ownership b Helps protect your investment in Modbus Plus while migrating to Ethernet b Dual Ethernet ports allow connection of both the M340 or M580 PLC and the configuration PC to the proxy, without any additional switches Processors: page 1/8 Ruggedized Modicon M580 modules: page 3/2 Compact 984 Distributed I/O Modbus Plus SCADA Modbus Plus Proxy Web configuration interface Modicon M340 Modicon M580 Ethernet 2 1 3 4 5 6 7 8 9 10 2 1 3 4 5 6 7 8 9 10
