Modbus TCP/IP Links with the MVI69L-MBTCP
The MVI69L-MBTCP adds Modbus TCP/IP client and server communication to Rockwell CompactLogix controllers. This module exchanges register data between the PLC and Modbus devices across the plant network. System integrators therefore apply it when connecting drives, meters, and remote I/O. Its single-slot format fits standard CompactLogix chassis without extra adapters.
Detailed Technical Parameters
Client and server handling defines the MVI69L-MBTCP, because the module runs both Modbus roles on dedicated firmware. The backplane interface exchanges data with the CompactLogix processor. Meanwhile, the Ethernet port connects directly to plant switches. Review the essential specifications in the table below.

Integration into Control Systems
The MVI69L-MBTCP fits into a standard CompactLogix slot and connects through the backplane connector. Commissioning engineers configure server lists and register mapping through the setup software. Consequently, Modbus links return to service quickly after module replacement. The device handles client polling and server requests within fixed scan intervals. Furthermore, the metal faceplate shields the circuitry from interference in electrical rooms.
Why Plants Choose This Module
Many facilities still operate Modbus devices for their proven field reliability. Hence, the MVI69L-MBTCP serves as a dependable spare for keeping data links online. Its standardized slot format simplifies stock management across multiple sites. In addition, the dual client and server roles reduce extra gateway hardware. This module keeps register data flowing and production schedules on track.
