| Rack Location | Local or remote rack |
| Backplane Current Load | 800 mA @ 5 Vdc; 3 mA @ 24 Vdc |
| Data Transfer | Ladder Logic between module and processor |
| Configuration | User-defined ladder logic; sample ladder file supplied |
| Modbus Modes | RTU with CRC-16; ASCII with LRC error checking |

| Floating-Point Data | Supported, including configurable Enron, Daniel and other implementations |
| Slave Node Address | 1 to 247, software selectable |
| Master Operation | Each configured Master port actively issues Modbus commands to other nodes. |
| Master Command List | Up to 100 commands per Master port; function, slave address, register addressing and word/bit count are configurable. |
| Polling | Continuous, on-change, dynamically user-enabled or automatically enabled. |

The module installs as a Generic 1756 module. ProSoft provides a commented sample ladder program with data types, ladder rungs and controller tags to support configuration.
Application-port wiring is selected through the module jumper settings, while the configuration/debug connection uses RS-232.
Typical system: ControlLogix-based automation systems that require serial Modbus communication with compatible PLCs, process devices, control devices or SCADA-connected equipment.
Common search trigger: loss of Modbus data exchange, command errors, serial-port communication problems, unexpected slave status, or missing data between the controller and Modbus network.
Downtime risk: a failed communication interface can interrupt the exchange of monitoring data or control commands between the controller and connected Modbus equipment.
Front-panel LED indicators show module, backplane transfer, application and serial activity. Command-level errors, slave status, counters and port status are also available for troubleshooting.
For the MVI56-MCM, the official PDF manual and datasheet provide installation, configuration, Modbus function, wiring and diagnostic information.
AMIKON supports industrial automation spare-part sourcing with model-level identification, supply coordination and pre-shipment handling.
For communication modules and legacy automation hardware, accurate part-number matching helps reduce unnecessary replacement and commissioning delays.
Share the complete model, required quantity and system information so the quotation can be prepared around the actual requirement.
Send the complete part number and application details for quotation and availability checking.
It is designed to interface with Rockwell Automation ControlLogix processors through the 1756 backplane.
Yes. Each application port can be configured for Modbus Master or Modbus Slave operation.
The application ports support RS-232, RS-422 and RS-485, with configurable communication parameters.
The official specification allows up to 100 configurable commands on each Modbus Master port.
ProSoft Technology currently lists the MVI56-MCM under its Legacy Products section and provides its datasheet, user manual and lifecycle documentation.
