North Coast Part # 341843

Features and Benefits

  • The MVI56-DNPSNET (Distributed Network Protocol Module over Ethernet) allows Rockwell Automation ControlLogix processors to easily communicate with other DNP protocol-compatible devices.
  • The module supports DNP subset level 2 features and some Level 3 features. The MVI56-DNPSNET module acts as an input/output module between the DNP Ethernet network and the Rockwell Automation backplane. The data transfer from the ControlLogix processor is asynchronous from the actions on the DNP network. Databases are defined in the module to house the data required by the protocol.


  • With the growing usage of the DNP protocol over Ethernet technology in the industrial marketplace, this product has a wide variety of application uses. Industries that use this technology include:
  • Power and distribution applications
  • Petrochemical
  • Water and Gas Applications
  • SCADA and DCS applications


  • Single Slot - 1756 backplane compatible
  • The module is recognized as an Input/Output module and has access to processor memory for data transfer between processor and module
  • Ladder Logic is used for data transfer between module and processor. Sample ladder file included.
  • Configuration data obtained from configuration text file downloaded to module. Sample configuration file included
  • Local or remote rack
  • The MVI56-DNPSNET module accepts DNP commands to control and monitor the data stored in the DNP databases. This data is passed between the module and the ControlLogix processor over the backplane for use in user applications.
  • DNP databases to house data for the slave port supporting the following maximum input counts
  • Binary input: 8000 points (500 words)
  • Binary output: 8000 points (500 words)
  • Counter: 250 (500 words)
  • Analog input: 500
  • Analog output: 500
  • Float Input: 150
  • Float Output: 150
  • User-definable module memory usage up to maximum point counts
  • Data movement between module using input/output image
  • Ethernet port supports both TCP and UDP over Ethernet
  • Supports DNP 3.0 in a level 2 implementation
  • Supports sending of input event data from the ladder to the module
  • Supports time synchronization from/to processor
  • Configurable via text file
  • Status and error information
  • All data in the DNP slave is contained in user-defined files
