The ProSoft MVI69E-MBTCP is a high‑performance industrial communication module manufactured by ProSoft Technology, Inc. It is specifically designed for use with Rockwell Automation’s CompactLogix series PLCs (Programmable Logic Controllers).
_____________________
1. Core Functions and Purpose
- Modbus TCP/IP Communication: As an enhanced Modbus TCP/IP communication module, it enables reliable read/write data exchange across industrial networks.
- Platform Compatibility: Engineered for CompactLogix controllers such as the 1769-L30 and L35, and fully compatible with RSLogix 5000 or Studio 5000.
- Network Topology: Supports up to 64 TCP/IP connections, allowing simultaneous communication with multiple Modbus devices including PLCs, drives, and instrumentation.

2. Operating Modes
- Server (Slave) Mode: The CompactLogix PLC acts as the master, while the MVI69E-MBTCP functions as a slave, responding to external Modbus clients.
- Master Mode: The MVI69E-MBTCP initiates read/write commands to external Modbus devices, such as the MVI56E-MCMXT module.
