Description

DNP 3.0 Ethernet Server Network Interface Module for SLC

MVI46-DNPSNET

The DNP 3.0 Ethernet Server Network Interface Module allows SLC processors to interface with the many field devices that support the DNP protocol over Ethernet. DNP (Distributed Network Protocol) is an open communication protocol developed to achieve inter-operability 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 MVI46-DNPSNET module to send a report to the processor without being polled, providing real time data transmission in critical situations.

 

Features and Benefits

The MVI46-DNPSNET (Distributed Network Protocol Module over Ethernet) allows Rockwell Automation SLC processors to easily communicate with other DNP protocol-compatible devices.

The module supports DNP subset level 2 features and some Level 3 features. The MVI46-DNPSNET module acts as an input/output module between the DNP Ethernet network and the Rockwell Automation backplane. The data transfer from the SLC processor is asynchronous from the actions on the DNP network. Databases are defined in the module to house the data required by the protocol and transferred using M0/M1 files.

 

Applications

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
