Description
Product Introduction & Engineering Value
Many modernization projects retain existing PROFIBUS field devices while upgrading the PLC platform. The GE IC695PBM300 bridges that gap by allowing PACSystems RX3i controllers to function as a PROFIBUS-DP master without replacing installed drives, remote I/O, or intelligent instruments.
Installed in an RX3i Universal Backplane, the module supports all standard PROFIBUS transmission speeds, DP-V1 acyclic messaging, and large network configurations. This makes it a practical choice for expanding or maintaining legacy automation systems while preserving existing field infrastructure.

Field Application & The “Trench” Experience
During the expansion of a steel rolling mill, engineers needed to integrate several existing PROFIBUS-controlled variable frequency drives into a new RX3i control platform. Replacing every field device would have required extended downtime and substantial rewiring.
An IC695PBM300 was installed as the PROFIBUS master, allowing the new PACSystems controller to communicate directly with the existing drives and distributed I/O stations. Production resumed with minimal modifications to the field network, reducing commissioning time while preserving proven equipment.
Typical application scenarios include:
- Continuous rolling mill drive coordination
- Cement kiln burner and drive communication
- Distributed conveyor systems with PROFIBUS remote I/O
- Paper machine drive synchronization using PROFIBUS-DP networks

The Veteran’s Tech Trap Guide
⚠️ Don’t Reuse an Old GSD File Without Verification
Many startup issues are caused by outdated or incorrect GSD files rather than defective hardware. Always confirm that every slave device uses the correct manufacturer-supplied configuration.
⚠️ Firmware Compatibility Matters
The IC695PBM300 requires an RX3i CPU running Firmware Version 2.9 or later. Verify CPU firmware before installing the module to avoid unnecessary commissioning delays.
PRO TIP:
If several PROFIBUS devices suddenly disappear from the network, inspect cable termination and station addresses before replacing the master module. In field service, wiring faults are considerably more common than PBM300 hardware failures.
⚠️ Watch Total Network Data Size
Although the module supports up to 125 slaves, overall input/output memory and parameter data are limited by CPU resources and PROFIBUS configuration. Large networks should be validated during project design rather than after commissioning.
Dynamic FAQ
Q1. What is the primary function of the IC695PBM300?
The allows a PACSystems RX3i controller to operate as a PROFIBUS-DP master, exchanging cyclic and acyclic data with distributed I/O, drives, HMIs, and other PROFIBUS-compatible devices.
Q2. How many PROFIBUS slave devices can the module support?
The module supports up to 125 PROFIBUS-DP slave devices, depending on network configuration and available controller memory.
Q3. Which PROFIBUS functions are supported?
The supports DP-V0 and DP-V1, including Sync, Freeze, Read, Write, and Alarm services, as well as all standard PROFIBUS transmission rates up to 12 Mbps.
Q4. Is New Surplus inventory genuine?
Yes. New Surplus units are genuine OEM inventory that has never been installed in production equipment. Every module is inspected for identification, connector integrity, and overall physical condition before shipment.
Q5. How are refurbished modules tested?
Refurbished modules undergo power-up diagnostics, PROFIBUS communication verification, firmware validation, LED testing, and functional network testing in an RX3i platform before shipment.
Q6. Does the require special programming software?
Yes. Configuration is performed using Proficy Machine Edition Logic Developer PLC, and firmware updates are installed through the WinLoader utility via the host RX3i CPU.
