Description

The 5136-DNP-PCI SST is a sophisticated, single-slot communication gateway module manufactured by ProSoft Technology, a global leader in industrial networking and a subsidiary of ABB. This module is engineered specifically for integration into Allen-Bradley ControlLogix® chassis, where it performs the critical role of a DNP3 (Distributed Network Protocol) Slave device. Its primary function is to bridge the gap between Rockwell Automation’s Logix control platform and master stations—such as SCADA systems, RTUs, or advanced HMIs—that utilize the DNP3 protocol, which is the industry standard for utility and critical infrastructure communications. The module allows a ControlLogix processor to efficiently and reliably exchange data with these upper-level systems, reporting process values, alarms, and events while receiving control commands.

As a key component in ProSoft’s renowned in-rack gateway family, the 5136-DNP-PCI SST is designed to provide a seamless, secure, and high-performance integration solution. It offloads the entire protocol translation processing burden from the main controller’s CPU, ensuring deterministic control system performance even during high-volume data exchanges. The module empowers engineers to leverage the powerful control capabilities of the ControlLogix platform while meeting the specific communication requirements of sectors like electric power, water, and oil and gas. The ProSoft Technology 5136-DNP-PCI SST is an indispensable tool for achieving vertical data integration and enabling comprehensive visibility and control over wide-area operational assets.

Main Features and Advantages

The 5136-DNP-PCI SST is packed with features designed for reliability and ease of use. Its most significant advantage is its native integration within the ControlLogix environment. Configuration is streamlined through an intuitive Add-On Profile (AOP) within Rockwell’s Studio 5000/RSLogix 5000 software, allowing engineers to map controller tags to DNP3 points without writing complex protocol-specific code. The module supports all DNP3 object variations and includes advanced features such as unsolicited reporting, which allows the outstation to immediately push critical event data to the master station without being polled, ensuring the fastest possible alarm notification.

The dual communication interfaces—Ethernet and serial—provide exceptional deployment flexibility, allowing connection to a wide range of DNP3 master stations. The module’s robust design includes a non-volatile memory that stores the configuration independently, facilitating quick and easy module replacement in the event of a failure without requiring a controller download. Comprehensive diagnostic capabilities are accessible both through the Studio 5000 software and a built-in web server, offering deep visibility into the status of the gateway and the DNP3 session. This powerful combination of features makes the 5136-DNP-PCI SST a highly reliable and secure data conduit for mission-critical applications.

Application Field

The primary application of the ProSoft Technology 5136-DNP-PCI SST is in the electric power industry, where it is deployed in substation automation systems. Here, it enables a ControlLogix-based PLC, acting as a relay or RTU, to communicate intelligently with a utility’s central SCADA master control room using the standard DNP3 protocol. It is critical for monitoring and controlling circuit breakers, transformers, reclosers, and capacitor banks, reporting real-time values and fault data to operators miles away.

Beyond electrical transmission and distribution, the 5136-DNP-PCI SST is extensively used in water and wastewater treatment facilities. It connects ControlLogix controllers managing pumps, filters, and chemical feed systems to a regional SCADA system for centralized monitoring and control of remote pump stations and treatment plants. In the oil and gas sector, it is implemented in pipeline monitoring and control systems (PSCADA) to gather data from remote turbine and compressor stations. Its reliability and compliance with a key industry standard make it the gateway of choice for any critical infrastructure application requiring secure and robust wide-area communication.

Installation and Maintenance

Pre-installation preparation: Before installing the 5136-DNP-PCI SST, ensure the ControlLogix chassis power is completely disconnected and properly locked out. Verify that the latest Add-On Profile (AOP) is installed in your Rockwell Automation Studio 5000 software. Review the DNP3 point list and database structure from the master station operator to plan the tag mapping within the Logix controller. For the SST version, ensure the serial communication wiring to the master station is properly prepared for connection to the screw terminal block.

Maintenance recommendations: The 5136-DNP-PCI SST requires minimal physical maintenance. The primary maintenance activities are performed through software, including regularly monitoring the module’s status and diagnostic counters via the Studio 5000 software or its built-in web server to ensure stable communication sessions. It is good practice to keep a backup of the module’s configuration file and to periodically check for firmware updates on the ProSoft Technology website to ensure optimal performance and security.
