Features:
- Single-slot ControlLogix backplane integration
- Two configurable Modbus RTU/ASCII application ports
- Independent master or slave role selection for each port
MVI56-MCM is identified as an in-chassis communication module, not an external gateway, and exchanges operational data through the controller backplane.
Its two application ports let one chassis coordinate separate Modbus serial duties while keeping their protocol roles and framing independently configured.
A correct service match depends on the saved controller data map, each port’s electrical interface and the original master-command or slave-address design.
For ProSoft MVI56-MCM Modbus Master/Slave Communication Module sourcing, Apter Power can help review the serial roles, port wiring and project record.
