Product Overview

The ProSoft ILX56-PBM is a high-performance PROFIBUS DPV1 Master/Slave communication module designed for Rockwell Automation ControlLogix 1756 platforms. It provides seamless integration between PROFIBUS field devices and the ControlLogix backplane, enabling deterministic cyclic data exchange and comprehensive DPV1 acyclic services. The module supports master and slave operation, automatic baud rate detection up to 12 Mbps, and connection of up to 125 slave devices with repeaters.

Engineered for demanding industrial networks, the ILX56-PBM simplifies commissioning through ProSoft Configuration Builder, generating AOIs and sample code for Studio 5000. Its isolated RS-485 interface and integrated diagnostics reduce downtime and improve system transparency. This module is suitable for connecting PLCs, drives, remote I/O, HMI panels, and sensors over PROFIBUS.

Product Specifications

Product Functions

The ILX56-PBM functions as a gateway and master controller on PROFIBUS networks. Its DPV1 master capability permits acyclic read/write services for parameterization, diagnostics, and alarm handling of intelligent field devices. The module supports cyclic data exchange with up to 125 slaves per segment, synchronized with the ControlLogix processor over the backplane using Class 1 and Class 2 connections. Integrated diagnostic buffers capture network events, slave failures, and communication errors, accessible via user-defined tags or ProSoft software. The slave mode allows the ILX56-PBM to act as a PROFIBUS slave to higher-level masters, providing flexibility in multi-vendor environments.

Advanced features include automatic baud rate detection, configurable I/O mapping, and robust isolation on the PROFIBUS port. Built-in LEDs indicate module status, network activity, and communication state, simplifying field troubleshooting.

Installation Highlights

The ILX56-PBM installs directly into any available slot of a ControlLogix 1756 chassis. No external power supply is required beyond backplane power. The isolated DB9 female connector supports standard PROFIBUS cables and connectors. Configuration is performed through ProSoft Configuration Builder software, which generates Add-On Instructions (AOIs) and example ladder logic for Rockwell Studio 5000. The module includes comprehensive diagnostic capabilities that map directly into ControlLogix tags, reducing integration effort. For hazardous areas, the module is certified for ATEX Zone 2 environments, provided the installation follows ProSoft guidelines.
