ProSoft Technology MVI69-DNP Communication Module

Configured for DNP 3.0 serial communication in CompactLogix control platforms, the ProSoft Technology MVI69-DNPPS (MVI69-DNP Communication Module) provides direct protocol execution between Rockwell Automation 1769 backplane systems and DNP 3.0 master or slave networks.

Hardware Specifications

Protocol Conversion and Industrial Network Integration

The MVI69-DNP module performs independent DNP 3.0 protocol processing while exchanging controller data through CompactLogix I/O data transfers. The module supports master and slave communication roles, allowing direct serial connection with SCADA systems, RTUs, and intelligent electronic devices.

Furthermore, the module provides configurable RS-232, RS-422, and RS-485 interfaces for serial network adaptation. DNP event handling includes Class 1, Class 2, and Class 3 event reporting with synchronized timestamps for monitored field data.

The ProSoft Technology communication architecture includes protocol conversion without requiring an external gateway device. The module communicates through the 1769 rack backplane and maintains data exchange between the processor and external DNP networks.

Protocol Conversion and Backplane Communication Features

The MVI69-DNP uses CompactLogix backplane bus communication for controller-side data transfer. The module firmware manages DNP 3.0 framing, message processing, and serial communication functions independently from the main controller scan execution.

The communication interface supports deterministic data exchange between Rockwell Automation PLC platforms and external serial devices. Configuration parameters define port operation, communication mode, and DNP data handling behavior.

The module supports firmware flash compatibility for maintaining communication functions within supported CompactLogix system configurations. Installation requires matching module firmware and controller platform requirements before system commissioning.

Frequently Asked Questions

Q: Does the MVI69-DNP require an external protocol converter for DNP 3.0 communication?
A: No. The module performs DNP 3.0 protocol processing internally and connects directly to supported CompactLogix 1769 I/O systems.

Q: Which serial electrical interfaces are available on the module?
A: The module provides two configurable serial ports supporting RS-232, RS-422, and RS-485 communication standards.

Q: How does the module exchange data with the CompactLogix processor?
A: The module exchanges data through standard 1769 backplane I/O transfers while independently managing DNP communication tasks.

Field Installation Guidelines

Install the MVI69-DNP module into a compatible 1769 CompactLogix rack following the controller manufacturer's slot installation requirements.

Verify that the backplane power supply capacity supports the module current demand before system startup. Connect serial communication wiring according to the selected RS-232, RS-422, or RS-485 interface configuration.

Use shielded communication cables for serial networks and terminate cable shields according to the site grounding practice. Separate communication wiring from high-voltage power conductors and high-current switching circuits to reduce electrical interference.

Confirm port configuration, baud rate settings, and DNP addressing parameters before connecting field devices. Perform communication testing between the PLC processor, module, and external DNP devices before placing the system into operational service.
