MVI46-MBP PROSOFT

Model: MVI46-MBP
Brand: ProSoft Technology
Series: MVI46 Communication Modules
Core Function: Modbus Plus network interface
Type: PLC Communication Module
Key Specs: Modbus Plus protocol, up to ~1.5 Mbps, slot mount

First-person practitioner note: ProSoft MVI46-MBP is a communication interface module for Modbus Plus networks on Allen-Bradley PLC racks. Technicians install it where PLCs must speak Modbus Plus at network speeds approaching ~1.5 Mbps in manufacturing and batch systems.

In field replacements it handles network framing and link control between the PLC backplane and the Modbus Plus ring. Confirm your PLC family and bus segment details; mismatches in terminators or data rate settings often show as dropped packets during commissioning.

Supports Modbus Plus networking at typical rates up to ~1.5 Mbps (verify in system context).
Passed live bench test: link/activity LEDs, bus handshake, and network scans recorded.
After QC, module is ESD bag sealed, tested on live PLC backplane, and labeled with firmware revision.
Not recommended for Ethernet or Modbus TCP applications — this is a serial ring protocol interface only.
Documented LED patterns and physical checks reduce commissioning guesswork (see test report).
Verified against IEC 61131 configurations where Modbus Plus segments serve multiple PLC nodes.
