As part of ProSoft Technology’s esteemed MVI56 series, the MVI56E-MCMR is purpose-built for seamless integration into Allen-Bradley 1756 ControlLogix racks. Its single-slot design minimizes space requirements, making it ideal for both new system installations and retrofitting existing setups. The module supports dual independent serial ports (RS232/RS485/RS422), each configurable for Modbus master or slave operations, enabling flexible connectivity with a wide range of industrial devices—from variable frequency drives and sensors to HMIs and actuators. By translating Modbus protocols into the ControlLogix ecosystem, it eliminates communication silos, allowing engineers to manage diverse equipment through a single, unified interface.
