Product Introduction

PROSOFT MVI69L-MBTCP Modbus TCP/IP Lite module targets smaller CompactLogix L2/L3 applications requiring Modbus TCP client/server connectivity over a single Ethernet port. It occupies one standard 1769 slot and exchanges 240 words of I/O data with the processor using Add-On Profile and Add-On Instruction support in Studio 5000 v16+.

The module handles up to 10 client connections with configurable command lists plus 2 server connections (standard port 502 plus encapsulated port 2000), acting as a co-processor to minimize PLC scan impact while configuration lives in the ACD project file. Engineers choose this “Lite” variant when full E-series connection capacity exceeds application needs.

Frequently Asked Questions (FAQ)

Q: Does the MVI69L-MBTCP support hot-swapping in a CompactLogix rack?
A: Honestly, treat it like every other 1769 communication module and schedule replacement during a controlled outage. The backplane tolerates insertion/removal but losing 10 client connections plus 2 servers will drop SCADA polling and drive control simultaneously. Inhibit the module via Studio 5000 tags, confirm process tolerance for Modbus TCP outage, cycle CPU to Program mode, and verify 5 V stability before handling hardware.

Q: Is the MVI69L-MBTCP obsolete, and is there a direct replacement?
A: The “L” (Lite) designation positions it as a current lower-capacity option for CompactLogix L2/L3 platforms versus full E-series modules. Check PROSOFT lifecycle before new designs; if consolidation occurs, expect migration toward higher-capacity MVI69E-MBTCP or newer CompactLogix-native Ethernet modules, but validate exact client/server limits, I/O image size, and AOP compatibility before assuming interchangeability.
