When you need Modbus® TCP/IP communications, the MVI56E-MNETC/MNETCXT is the module of choice. The Modbus TCP/IP Enhanced Communications Module allows Rockwell Automation® ControlLogix® Programmable Automation Controllers (PACs) to interface easily with Modicon® Programmable Automation Controller (PACs), as well as multiple Modbus TCP/IP server-compatible instruments and devices. The multi-client module improves performance when controlling multiple servers on a Modbus TCP/IP network, by supporting up to 30 Client connections. It also supports up to 40 server connections providing the ability to communicate with other DCS and SCADA systems. Both client and server functionality can run simultaneously, allowing the module to operate as a powerful data concentrator.

The MVI56E-MNETC and MVI56E-MNETCXT are functionally the same. The MVI56E-MNETC is designed for standard process applications. The MVI56E-MNETCXT is designed for the Logix-XT™ control platform, allowing it to operate in extreme environments. It tolerates higher operating temperatures and has a conformal coating to protect it from harsh or caustic conditions.

MVI56E enhancements include configuration and management through the module’s Ethernet port, and CIPconnect® technology for bridging though ControlNet™ and EtherNet/IP™ networks.
