Modbus TCP/IP Communication Solution – ProSoft Technology MVI56-MNETC | MVI56 Series
Where This Product Is Used
The ProSoft MVI56-MNETC is deployed wherever Allen-Bradley ControlLogix PLCs must exchange real-time data over Modbus TCP/IP Ethernet networks. Typical application environments include:
- Water & Wastewater Treatment Plants — SCADA integration between ControlLogix controllers and third-party RTUs, flow meters, and pump drives using Modbus TCP
- Oil & Gas Pipelines — Remote terminal unit (RTU) polling across long-distance Ethernet backbones; master/slave configurations for pressure and flow instrumentation
- Power Generation & Utilities — Substation automation linking ControlLogix to protective relays, energy meters, and IEDs that speak Modbus TCP
- Automotive & Discrete Manufacturing — Machine-level data acquisition from servo drives, VFDs, and vision systems on the plant Ethernet segment
- Food & Beverage Processing — Integration of weighing systems, filling machines, and temperature controllers into a unified ControlLogix architecture
- Building Automation & HVAC — BMS gateway applications bridging Modbus TCP field devices to Rockwell Automation control systems

Why Engineers Specify This Model
- Simultaneous Client & Server — The MVI56-MNETC operates as both a Modbus TCP client (initiating polls) and server (responding to external masters) in the same module, eliminating the need for two separate gateways.
- Ladder Logic Configuration — All connection parameters are configured directly in RSLogix 5000 / Studio 5000 via MSG instructions and Add-On Instructions (AOI), keeping engineering within the familiar Rockwell environment.
- Deterministic Data Transfer — Backplane data exchange with the ControlLogix processor is synchronised to the PLC scan cycle, ensuring consistent, predictable latency for process-critical data.
- Scalable Architecture — Supports up to 16 client + 16 server connections per module; multiple modules can be installed in the same chassis for high-density applications.
- Proven Field Reliability — Widely deployed across water, oil & gas, and power sectors for over a decade; extensive ProSoft documentation and sample code available.

Application-Specific FAQ
Q: Can the MVI56-MNETC poll multiple Modbus TCP slave devices simultaneously?
A: Yes. As a client, it supports up to 16 concurrent TCP connections, each independently configured with its own IP address, port, and register map.
Q: Does it work with Studio 5000 Logix Designer v32 and later?
A: Yes. ProSoft provides updated AOIs and sample programs compatible with Studio 5000 v21 through v36+. Always download the latest package from ProSoft’s website.
Q: What is the maximum number of MVI56-MNETC modules per ControlLogix chassis?
A: Limited only by available chassis slots and backplane current budget. Practically, 4–6 modules per chassis is common in high-density gateway applications.
Q: Is the module compatible with 1756-EN2T or 1756-EN3TR Ethernet bridges?
A: The MVI56-MNETC has its own dedicated RJ-45 Ethernet port and does not rely on the ControlLogix Ethernet bridge for Modbus TCP traffic. Both can coexist in the same chassis.
Q: Can it act as a Modbus TCP server for a SCADA system like Ignition or Wonderware?
A: Yes. In server mode, the module exposes its internal data table to any Modbus TCP master, including Ignition, Wonderware, iFIX, and most HMI/SCADA platforms.
