DNP 3.0 Master/Slave Network Interface Module for ControlLogix

The DNP 3.0 Master/Slave Network Interface Module allows ControlLogix processors to interface with the many field devices that support the DNP protocol. DNP (Distributed Network Protocol) is an open communication protocol developed to achieve interoperability among systems specifically in the electric utility, oil & gas and water/wastewater industries.

This non-proprietary protocol, available worldwide, was designed to optimize the transmission of data acquisition information and control commands. It is a highly efficient and reliable communications protocol between substation computers, RTUs, IEDs and master stations. DNP is also a layered protocol, featuring time stamping and True Report by Exception (TRBE). These features allow the MVI56-DNP module to send a report to the processor without being polled, providing real time data transmission in critical situations.

Features and Benefits

The module supports DNP Subset Level 2 features and some of the Level 3 features allowing the many SCADA and field devices supporting the DNP protocol to be integrated into the ControlLogix platform. The module acts as an input/output module between the DNP network and the ControlLogix processor. The data transfer from the ControlLogix is asynchronous from the actions on the DNP network. Databases are user defined and stored in the module to hold the data required by the protocol.

Specifications

  • 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 module has two DNP protocol ports that can be user configured to operate in a Master/Slave or in a Slave/Slave redundant port configuration.

User defined internal register space is accessible to the protocol driver and to the ControlLogix processor memory.
