This module enables ControlLogix controllers to operate as Modbus Masters or Slaves on two independently configurable serial ports, allowing simultaneous connection to different Modbus networks. The MVI56E-MCM serves industrial automation environments demanding high reliability in data exchange, including cyclic and acyclic communications tailored for real-time process control and diagnostics. Its design directly addresses challenges related to multitier network architecture and legacy device integration without compromising control system performance.
Fitting in a single slot of the 1756 ControlLogix backplane, the MVI56E-MCM acts as an I/O module presenting Modbus data transparently to the processor. Engineers benefit from user-configurable memory mapping supporting up to 10,000 16-bit registers, simplifying data handling and improving control precision. The module is CIPconnect® enabled for enhanced network diagnostics and communication via EtherNet/IP and ControlNet bridges, supported through Rockwell Automation’s ecosystem.
Featuring a 4-character scrolling alphanumeric LED display, the MVI56E-MCM provides plain-language status, error, and configuration feedback facilitating straightforward troubleshooting. The module also supports ProSoft Discovery Service (PDS) software for quick device identification and temporary IP addressing during configuration. Its ruggedness extends to meeting industrial standards of vibration, shock, and temperature, ensuring reliable operation from 0°C to 60°C, with certification options for harsher conditions via the MCMXT variant.
