Modbus Plus to DNP over Ethernet Communication Module
5303-MBP-DNPSNET
Product Description
The ProLinx family Modbus Plus to DNP over Ethernet communications module (5303-MBP-DNPSNET) creates a powerful connection between devices on a DNP over Ethernet network and a Modbus Plus device. The module, encased in aluminum (ProLinx Plus 5000 series), is a stand-alone DIN-rail mounted protocol gateway that provides one Modbus Plus configurable DB9F port and one Ethernet port.
The Modbus Plus protocol driver exists in dual Modbus Plus Ports (MBP). The driver can be configured on an individual port basis as either a master or a slave to interface with other Modbus Plus devices. The Modbus port is fully configurable, providing a great deal of flexibility.
The ProLinx module is capable of supporting the DNP 3.0 protocol as a server using the TCP and UDP protocols using service port 20000. This port is fully configurable, providing a great deal of flexibility.
Product Applications
The MBP-DNPSNET modules are the ideal solution for the many applications where DNP over Ethernet connectivity can be used to integrate a Modbus Plus device into a system.
The DNP over Ethernet gateway is a powerful module designed with both Client and Server support, enabling easy connection to other DNP devices. In combination with the Modbus Plus support, the module provides a very powerful interface to the many Modbus Plus devices which are in use in the industrial marketplace today. Applications for the module are found in most industries, especially the Manufacturing, Oil and Gas, Electrical Power and Food Processing.
Functional Specifications
Internal Database
The ProLinx module contains an internal database that consists of areas for application data, status information, and configuration information.
The internal database is shared between all ports on the module and is used as a conduit to pass information from a device on one network to one or more devices on another network.
Application Data Area
The data area is used to store and retrieve data by the protocol drivers and for data exchange between protocols. The database is used as a source for write commands to remote devices and holds data collected from the remote devices. Commands defined in the configuration file (stored in the configuration data area) control how the data is to be handled in the database.
Status Data Area
This area is used to store error codes, counters, and port status information for each port.
Configuration File
This file contains module configuration information such as port configuration, network information, and command configuration. This configuration file is downloaded to, or uploaded from, the module.
Modbus Plus Port Specifications
The Modbus Plus protocol driver exists in dual Modbus Plus Ports (MBP). The driver can be configured on an individual port basis as either a master or a slave to interface with other Modbus Plus devices.

DNPSNET Protocol Specifications
The DNPSNET protocol driver exists as a single service port (DNPSNET port 20000) implementation that supports a single TCP port connection and multiple UDP ports on a TCP/IP Ethernet network. The DNPSNET port operates as a server, supporting the DNP 3.0 protocol in a Level 2 implementation using the DNP User Group recommended extension for use on LAN/WAN. This is published in "Transporting DNP V3.00 over Local and Wide Area Networks", December 15, 1998 by the DNP Users Group and is available on the Internet at http://www.dnp.org.
The DNPSNET driver will respond to requests from a remote DNP client (master) device. All data in the module's database configured as DNP data points is available to the remote master device for read and write requests. Additionally, the driver can send unsolicited event messages to a connected, TCP, client.
