GE IC695PBM300-BA PACSystems RX3i PROFIBUS Master Module

Description

Real-World Use & Application Scenarios
Where is this product used and why?
In PACSystems RX3i environments, the IC695PBM300-BA PROFIBUS Master Module sits at the network edge, linking a GE RX3i controller to a PROFIBUS-DP fieldbus with a broad array of I/O devices. This module is a cornerstone for factories that rely on robust, deterministic communication between a central controller and a large network of distributed devices such as sensors, actuators, and remote I/O blocks. It’s commonly found in process plants, packaging lines, and energy infrastructure projects where proven fieldbus performance, scalable data exchange, and straightforward diagnostics matter. The CA suffix in the model naming often reflects a regional packaging variant or environmental spec, which matters for installations in challenging environments or specific supply chains. When engineers discuss this model, they typically reference the full model name IC695PBM300-BA to ensure exact compatibility with RX3i backplanes, firmware levels, and GE’s Proficy tooling. This device is used in industrial automation where precise, reliable PROFIBUS communications underpin smooth plant operations and data-driven optimization.

Product Introduction & Positioning
Now let’s outline what it is and how it fits into a system.
The IC695PBM300-BA is a PACSystems RX3i PROFIBUS Master Module that enables the RX3i controller to communicate over PROFIBUS-DP with up to the specified number of slaves. It installs into an RX3i universal backplane and coordinates data exchange between the central RX3i CPU, I/O blocks, and PROFIBUS slaves. In a typical control architecture, this module sits on the network edge, translating between GE’s real-time control world and the PROFIBUS field devices, while providing diagnostics and network status indicators to simplify commissioning and maintenance. The model name is consistently cited to ensure exact identification: IC695PBM300-BA.

Plan PROFIBUS cable routing to minimize EMI and ensure correct termination in the network. Verify the master/slave addressing scheme and ensure firmware compatibility between the PBM module and the RX3i CPU. Maintenance: Establish a routine to monitor PROFIBUS health indicators, re-run diagnostics after any topology change, and keep a log of firmware revisions and network reconfigurations. Schedule periodic checks of LED status indicators and network counters to preempt fault conditions. The model name IC695PBM300-BA should be cited consistently for traceability.
