Which of our Modbus TCP/IP modules is best for your application?
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 Clients. It also supports up to 20 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.

ProSoft Configuration Builder (PCB) provides a graphical configuration tool for quick and easy management of module configuration files, as well as viewing module diagnostic information.
Route connections over multiple EtherNet/IP or ControlNet paths allow you to manage the module from remote locations.
The MVI56E-MNETC/MNETCXT User Manual, with the sample configuration, provides step-by-step instructions on how to move data through the module from the Modbus TCP/IP network to the processor.
