PROSOFT MVI69-MCM Modbus Communication Module – MVI69 Series for CompactLogix
Imagine a critical production line where your CompactLogix PLC cannot communicate with legacy Modbus RTU/ASCII field devices — drives, meters, sensors, and remote I/O panels all go silent. Without a dedicated protocol bridge, engineers face costly custom wiring, unreliable polling, and unplanned downtime that ripples across the entire facility. The PROSOFT MVI69-MCM eliminates this gap entirely, delivering seamless, deterministic Modbus communication directly inside the CompactLogix backplane.
The MVI69-MCM occupies a unique position within ProSoft Technology’s MVI69 series: it is the purpose-built, dual-port Modbus Master/Slave solution engineered specifically for the Allen-Bradley CompactLogix platform. Trusted by system integrators and OEMs across oil & gas, water treatment, power generation, and discrete manufacturing, this module has become a de facto standard for Modbus connectivity in mid-range Rockwell Automation architectures worldwide.

Key Features & Benefits
- Dual Independent Serial Ports — Run two separate Modbus networks simultaneously, reducing hardware count and panel space.
- Master & Slave in One Module — Operate as Modbus Master on one port and Slave on the other, enabling flexible multi-tier architectures.
- Backplane Pass-Through — Data is exchanged directly with the CompactLogix processor via the 1769 backplane, ensuring deterministic, low-latency updates.
- ProSoft Configuration Builder (PCB) — Free Windows-based configuration utility with intuitive interface; no ladder logic required for basic setup.
- Extensive Diagnostic Registers — Real-time error counters, port status, and message statistics accessible from the PLC program for predictive maintenance.
- Wide Baud Rate Range — Supports legacy slow-speed devices up to high-speed modern instruments without hardware changes.
- Hot-Swap Capable — Supports removal and insertion under power (RIUP) in compatible CompactLogix systems, minimizing maintenance downtime.
Industry & Equipment Applications
- Oil & Gas: Wellhead RTUs, flow computers, pressure transmitters, and SCADA integration via Modbus RTU over RS-485.
- Water & Wastewater: Pump station VFDs, level sensors, chlorination controllers, and remote lift stations.
- Power Generation & Utilities: Generator controllers, UPS systems, power meters, and substation automation.
- Discrete Manufacturing: Servo drives, weigh scales, barcode readers, and third-party HMI panels.
- Building Automation: HVAC controllers, energy meters, and BMS gateways requiring Modbus connectivity.

Frequently Asked Questions
Q: Is the MVI69-MCM compatible with all CompactLogix controllers?
A: The MVI69-MCM is compatible with the 1769 CompactLogix backplane family. It is not compatible with ControlLogix (1756) or MicroLogix platforms. Always verify your controller’s catalog number before ordering.
Q: Can the MVI69-MCM act as both Modbus Master and Slave simultaneously?
A: Yes. Each of the two serial ports can be independently configured as Master or Slave, allowing the module to bridge two separate Modbus networks or serve both roles concurrently.
Q: What software is required to configure the MVI69-MCM?
A: ProSoft Configuration Builder (PCB) is the primary configuration tool and is available as a free download from ProSoft Technology’s website. Studio 5000 / RSLogix 5000 is required for the PLC-side Add-On Instruction (AOI) integration.
Q: Do you provide the configuration files or sample ladder logic?
A: We can share standard ProSoft sample code upon request. For custom integration support, please describe your application in your inquiry.
Q: What is the lead time for the MVI69-MCM?
