IC695PBM300 GE Fanuc PACSystems RX3i Network Controller Module

Brief Product Description

The GE Fanuc IC695PBM300 acts as a high-performance PROFIBUS DP Master module for the PACSystems RX3i controller platform. This module establishes high-speed decentralized fieldbus networks, enabling seamless data exchange between the central processor and up to 125 distributed field devices.

Product Overview

The GE Fanuc IC695PBM300 provides comprehensive network management capabilities for industrial control systems utilizing the PACSystems RX3i architecture. Originally developed by GE Intelligent Platforms and now supported by Emerson Automation, this module integrates centralized automation processors with complex PROFIBUS DP fieldbus topologies. Because modern industrial facilities demand high-density data distribution, this interface module manages up to 3,584 bytes of total input data alongside 3,584 bytes of total output data simultaneously.

By operating as a dedicated network master node, the module coordinates communication with as many as 125 distinct DP slave units over a single fieldbus segment. Each connected node transmits up to 244 bytes of input data and receives up to 244 bytes of output data per cycle. Furthermore, the hardware fully supports advanced PROFIBUS DP-V1 extended functions. This protocol compliance enables engineers to handle acyclic Read/Write parameters and diagnostic alarm messages without interrupting cyclic process monitoring. To maximize diagnostic transparency, the module continuously reports essential status telemetry, including specialized Network Diagnostic Counters, DP Master Diagnostic Tables, and a real-time Slave Status Bit Array. (Note: While the provided raw table erroneously references an “Ethernet router” function under communication services, this component operates exclusively as a serial PROFIBUS DP network master.)

Architectural Layout and Physical Implementation

The physical architecture of the module optimizes deployment within standard PACSystems RX3i universal backplanes. For field connectivity, a rugged, industry-standard 9-pin Sub-D female connector ensures mechanical and electrical stability under high-vibration conditions. The system draws 440 mA of operating current from the 3.3 VDC backplane rail, which minimizes thermal loading inside the local rack assembly.

To streamline commissioning and troubleshooting, the front panel features integrated, PROFIBUS-compliant LED status indicators. These indicators provide immediate visual feedback regarding network health and inner module logic processing. Plant engineers configure the interface using Proficy Machine Edition software (Version 5.0 SP2 or later), provided the host RX3i controller runs system firmware version 2.90 or higher. For long-term lifecycle management, field technicians can upgrade the operational firmware over the backplane using standard WinLoader software utilities.
