ProSoft MVI69-MNET Modbus TCP/IP Communication Module

Product Description

Configured for Modbus TCP/IP data exchange in a Rockwell CompactLogix system, the ProSoft MVI69-MNET (MVI69MNET Modbus TCP/IP Communication Module) provides direct communication between the CompactLogix backplane and Modbus TCP/IP devices. The module occupies one 1769 slot and transfers application data through ladder logic.

Hardware Specifications

Protocol Conversion and Network Interface

The MVI69-MNET handles Modbus TCP/IP communication for a CompactLogix controller. The module exchanges application data with the controller through the 1769 backplane and ladder logic.

The module supports up to 5000 registers and up to 100 client commands. Therefore, the application can define multiple Modbus TCP/IP transactions while maintaining the controller-side data interface through ladder logic.

As a ProSoft communication module, its dedicated function focuses on protocol conversion and industrial network data exchange rather than local I/O signal conditioning.

Frequently Asked Questions

Q: How many CompactLogix slots does the MVI69-MNET occupy?
A: The module occupies one standard 1769 single-slot position.

Q: What is the maximum backplane current load?
A: The specified maximum current load is 800 mA at 5 VDC.

Q: How does the CompactLogix controller exchange data with the module?
A: The supplied specification identifies ladder logic as the data-transfer method between the controller application and the communication module.

Field Installation Guidelines

• Install the module in the designated 1769 system slot and verify mechanical engagement with the adjacent system components.
• Confirm that the CompactLogix power system can support the module's specified 800 mA maximum load at 5 VDC.
• Route Ethernet communication wiring separately from high-voltage power conductors and high-current switching circuits where practical.
• Maintain proper cable shielding and grounding practices according to the installed Ethernet infrastructure and site electrical standards.
• Verify network addressing and Modbus TCP/IP communication parameters before commissioning.
• Check ladder-logic data mapping against the intended Modbus register allocation before placing the controller into service.
• Confirm that the configured client commands remain within the specified maximum of 100 commands.
• Inspect all connectors and terminal interfaces for secure mechanical engagement before energizing the system.
