Prosoft MVI56E-MCM

The Prosoft MVI56E-MCM with available stock uses the most advanced ControlLogix 1756 rack and can be directly inserted into the ControlLogix rack to act as a universal converter, converting the high-speed backplane instructions of the PLC into serial signals that the field instruments can recognize. Yueyang Tongtu is a supplier that offers high-quality products, allowing you to collect data from those old but useful devices without adding an additional gateway cabinet..

Structure

The core architecture of this Prosoft MVI56E-MCM is a high-performance communication processor that operates independently of the main PLC. This chip is dedicated solely to handling the complex serial data packaging, unpacking, and protocol conversion. This ensures that the CPU resources of the main PLC are not occupied by communication tasks, and it prevents the entire control logic scanning cycle from being slowed down due to reading instrument data. The circuit board integrates two completely electrically isolated serial port driver circuits. This is to prevent the long communication line in the field from bringing back lightning strikes, surges, or ground loop interference to the rack. By making the isolation solid, even if the outside line shorts, it will not damage your expensive ControlLogix backplane.

Performance Features

The Prosoft MVI56E-MCM is an enhanced communication module specifically designed for the ControlLogix system. It features two independent configurable serial ports. Each port supports the RS232/RS485/RS422 electrical standards and a wide range of baud rates from 110bps to 115.2kbps. It can be freely set as the master or slave station for Modbus RTU/ASCII, and can operate across the same or different Modbus networks. It is compatible with multiple protocols and fully supports standards such as Modbus TCP/IP, EtherNet/IP, DF1, EtherCAT, gLink-II, and Modbus 485. It can easily adapt to various network topologies like star and ring, as well as complex application scenarios.
