Modbus TCP/IP Client/Server Enhanced Network Interface Module with Reduced Data Block for ControlLogix


Which of our Modbus TCP/IP modules is best for your application?

Watch this Video


The Modbus TCP/IP Client/Server Enhanced Communication Module with Reduced Data Block allows Rockwell Automation ControlLogix processors to interface easily with Modbus TCP/IP-compatible devices, such as Modicon Programmable Automation Controllers (PACs) and a wide variety of Modbus TCP/IP-compatible instruments and devices.

The MVI56E-MNETR uses a reduced Input/Output (I/O) data image block size for transferring data between itself and a ControlLogix processor. This makes it ideal for remote rack applications using ControlNet or EtherNet/IP process networks. The module also works well for applications that require redundant ControlLogix processors.

MVI56E-MNETR enhancements include local and remote configuration and diagnostics through the module's Ethernet port, CIPconnect technology for bridging though Rockwell Automation ControlNet and EtherNetIP networks, and an on-board web server for access to module documentation and sample program files.

特性 优势


  • Upgrade earlier MVI56-MNETR modules without changing existing ladder logic programs or module configurations
  • Enhanced features and flexibility without incurring expensive reprogramming costs

RSLogix 5000 Integrated

  • Module communication is integrated within RSLogix 5000 using a sample Add-On Instruction (AOI) or sample ladder logic file
  • No additional programming and/or configuration software are required

Reduced Input/Output Image Size

  • Uses less bandwidth on process control networks like ControlNet or EtherNet/IP
  • Optimizes communication for more efficient remote rack installations, especially when using redundant ControlLogix processors

Graphical User Interface Software

  • ProSoft Configuration Builder (PCB) provides online or offline configuration and online diagnostics using the high-speed Ethernet port
  • CIPconnect-enabled, allows remote configuration and diagnostic access across multiple bridged EtherNet/IP and ControlNet networks using Rockwell Automation 1756-ENxT and 1756-CNB network interface modules

Web-enabled Ethernet port with Discovery Service

  • Module's built-in Ethernet port provides a web server for local access to documentation, module status, and firmware updates
  • ProSoft Discovery Service, a software utility to locate MVI56E modules on the network and assign a temporary IP address for easy configuration


  • Backward-compatible with previous MVI56-MNETR versions
  • Single-Slot ControlLogix backplane compatible
  • 10/100 Mbps auto crossover detection Ethernet configuration and application port
  • User definable module data memory mapping of up to 5000, 16-bit registers
  • CIPconnect-enabled network configuration and diagnostics monitoring using ControlLogix 1756-ENxT and 1756-CNB modules and EtherNet/IP pass-through communication
  • Reduced I/O image size designed specifically to optimize remote rack implementations
  • ProSoft Configuration Builder (PCB) software supported, a Windows-based graphical user interface providing simple product and network configuration
  • Sample ladder logic and Add-On Instructions (AOIs) are used for data transfer between module and processor
  • Internal web server provides access to product documentation, module status, diagnostics, and firmware updates
  • 4-character alpha-numeric scrolling LED display of status and diagnostics data in plain English - no cryptic error or alarm codes to decipher
  • ProSoft Discovery Service (PDS) software used to locate the module on the network and assign temporary IP address
  • Personality Module - a non-volatile, industrial-grade Compact Flash (CF)card used to store network and module configuration, allowing quick in-the-field product replacement by transferring the CF card
