Siemens Industrial Ethernet Communication Module


The MVI56E Siemens Industrial Ethernet Communication Module allows Rockwell Automation ControlLogix Programmable Automation Controllers (PACs) to interface easily as an Ethernet Client with up to a maximum of 20 Siemens S7-200, S7-1200, S7-300, and S7-400 PLCs operating as Ethernet servers.

The module uses ProSoft Configuration Builder (PCB) which provides a graphical configuration tool for management of module configuration files, as well as viewing communication and module diagnostic information using the high-speed Ethernet port.

Commands are enabled/disabled from ladder logic enabling various Siemens S7 CPUs to support multiple applications without having to reconfigure the module. Data transfer to a ControlLogix ® PAC uses scheduled I/O data for faster updates and better performance.

Features and Benefits



Backward Compatibility

  • All MVI56E Enhanced products are backward-compatible with earlier MVI56 modules, allowing direct replacement without the need to change existing controller programs
  • Enjoy Enhanced features and flexibility without incurring expensive reprogramming costs

RSLogix 5000 Integrated

  • Module configuration and communication is integrated within RSLogix 5000
  • No additional programming or configuration software is required
  • Add-On Instruction for RSLogix 5000 version 16 or higher cuts development time and costs


  • ProSoft Configuration Builder software (PCB), with CIPconnect, facilitates remote user access across the ControlLogix backplane through Rockwell Automation's 1756-ENBT or 1756-CNBT modules
  • Configure, diagnose, and analyze process data and communication status
  • CIPconnect can bridge through multiple ENBT/CNBT links to connect to MVI56E-MCMs installed in remote chassis for configuration and diagnostics

4-digit LED Display

  • A scrolling display for easily-understood, plain English diagnostic and error information
  • See critical configuration and status information without having to hook up to the port

Ethernet Port

  • Local and remote diagnostics access available through the Ethernet Port
  • Single-slot 1756 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
  • Add-On Instructions (AOI) are used for data transfer between module and processor
  • 4-character, alpha-numeric, scrolling LED display of status and diagnostics data
  • 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 for quick in-the-field product replacement.

Industries that use this technology include:

  • Power and distribution applications
  • Petrochemical
  • Water and Gas Applications
  • SCADA and DCS applications
