PROSOFT 1454-9F

Description

Introduction to the PROSOFT 1454-9F

Product Description

The PROSOFT 1454-9F is a specialized industrial communication gateway from ProSoft Technology (now part of Red Lion, a Spectris company), a leader in industrial connectivity solutions. This module functions as a protocol converter, specifically designed to bridge data between Allen-Bradley ControlLogix PLCs using EtherNet/IP and SCADA/HMI systems or devices utilizing the IEC 60870-5-101 protocol (also known as IEC 870-5-101 or T101). The PROSOFT 1454-9F enables a modern ControlLogix system to communicate seamlessly with legacy electrical utility equipment, remote terminal units (RTUs), and SCADA masters that operate on the standardized IEC 101 protocol, commonly used in power distribution and water/wastewater industries. By translating data tags and commands, it facilitates integration without the need to replace existing infrastructure.

Product Parameters

• Brand & Series: ProSoft Technology In-Rack Module Series

• Model: 1454-9F

• Device Type: In-Chassis Communication Gateway / Protocol Converter

• Protocol Side A: Native integration with Allen-Bradley ControlLogix via backplane. Appears as an I/O module in the Logix5000 controller’s I/O configuration.

• Protocol Side B: IEC 60870-5-101 (Serial Master or Slave) over an RS-232/RS-485 serial interface.

• Physical Interface: Features a serial port (DB-9) for the IEC 101 connection.

• Mounting: Installs directly into a ControlLogix chassis (1756 series) as a single-slot module.

• Configuration: Configured using ProSoft Configuration Builder (PSCB) software, which runs on a Windows PC.

• Data Mapping: Supports mapping of hundreds of points (coils, registers) between ControlLogix tags and IEC 101 data objects.

Advantages and Features

The primary advantage of the PROSOFT 1454-9F is its ability to solve a specific and complex interoperability challenge by providing a reliable, in-chassis solution. It eliminates the need for an external gateway PC or custom coding, reducing points of failure and simplifying system architecture. The module performs high-speed, deterministic data exchange directly over the ControlLogix backplane. It offers extensive diagnostic capabilities accessible through the PLC logic and the configuration software. As a ProSoft product, it is fully supported and comes with robust configuration tools, making a complex protocol translation manageable. The 1454-9F is known for its reliability in mission-critical applications.

Application Cases in Industry

This gateway is primarily used in industries where modern PLCs must interface with legacy utility telecontrol systems. In electrical transmission and distribution (T&D), the PROSOFT 1454-9F connects a ControlLogix-based substation automation system to a legacy SCADA control center using IEC 101. Within water and wastewater management, it enables a new plant control system (ControlLogix) to communicate with older RTUs in pump stations or remote reservoirs that use the IEC 101 standard. It is also used in oil and gas pipeline monitoring and in industrial facilities that have to report data to a utility’s master station.

Comparison with Competing Products

Competing solutions include generic protocol converters, software-based OPC servers, or custom communication drivers. The PROSOFT 1454-9F stands out as a dedicated, hardware-based solution that is tightly integrated with the ControlLogix platform, offering superior performance, reliability, and ease of integration compared to software running on a Windows PC. Competing hardware gateways from other vendors (like HMS Networks) may offer similar IEC 101 connectivity, but the 1454-9F benefits from ProSoft’s deep expertise and reputation in the Allen-Bradley ecosystem. Its main advantage is being a turnkey, supported solution for this specific protocol pair.

Selection Suggestions and Precautions

Selecting the PROSOFT 1454-9F is driven by the specific requirement to connect an Allen-Bradley ControlLogix system to an IEC 101 network. Determine the role (Master or Slave) and the serial parameters (baud rate, data format) required by the existing IEC 101 equipment. Assess the number of data points (coils, inputs, registers) that need to be mapped to ensure the module’s capacity is sufficient. Ensure a compatible slot is available in the ControlLogix chassis.

Precautions:

• Configuration is a specialized task. Personnel must understand both the ControlLogix tag database and the structure of the IEC 101 protocol (information object addresses, cause of transmission, etc.).

• The serial wiring (RS-232 or RS-485) must be correct, with proper termination for RS-485 networks.

• The module’s firmware and the configuration software (PSCB) should be kept up to date.

• Thorough testing of the data mapping in a controlled environment is crucial before commissioning to ensure all points are read/written correctly.
