ProSoft MVI56-DNP ControlLogix DNP 3.0 Master/Slave Network Interface Module

ProSoft MVI56-DNP ControlLogix DNP 3.0 Master/Slave Network Interface Module

Configured for DNP 3.0 master/slave communications in ControlLogix systems, the ProSoft MVI56-DNP (MVI56-DNP DNP 3.0 Network Interface Module) provides serial data exchange through Ladder Logic data transfer. The module supports local or remote rack installation, two serial ports, 110 to 115200 Baud operation, and communication with up to 40 slave devices.

Hardware Specifications

Protocol Conversion and Serial Communication

The MVI56-DNP transfers DNP 3.0 data between serial communication channels and ControlLogix Ladder Logic data structures.

Two serial ports are specified for external DNP communication connections, while baud rates range from 110 to 115200 Baud.

The module supports master and slave operating functions, with capacity for up to 40 slave devices.

User-defined command capacity reaches 300 entries, allowing application-specific DNP communication sequences to be configured.

Frequently Asked Questions (FAQ)

Q: How does the MVI56-DNP exchange data with the ControlLogix processor?
A: The supplied data specifies Ladder Logic as the data transfer method between the module and ControlLogix system.

Q: What backplane current does the module require?
A: The supplied specification lists 800 mA at 5 VDC for the backplane current load.

Q: Does the module support both master and slave DNP operation?
A: Yes. The product designation and supplied specifications identify DNP 3.0 Master/Slave communication functionality.

Field Installation Guidelines

Install the module in the designated ControlLogix rack slot and verify mechanical engagement before applying system power.

Route serial communication wiring separately from high-current conductors, motor leads, and switching power circuits to reduce electromagnetic interference.

Use appropriate shielded communication cable where required by the connected DNP equipment and terminate shielding according to the site grounding scheme.

Verify serial port assignments, baud rate, and communication parameters before placing the DNP network into service.

Confirm the available backplane current capacity against the module requirement before finalizing rack loading.

Do not assume hot-swap capability unless the applicable ProSoft hardware documentation explicitly permits module removal or insertion under power.

Maintain the specified operating environment from the applicable hardware manual because temperature and dimensional data were not provided in the supplied material.
