The GE Fanuc IC695PBM300 is a powerful PACSystems RX3i PROFIBUS DP Master module capable of controlling 125 slave devices.Supporting DP-V1 protocols and speeds up to 12 MBit/s, this module provides the high-speed data throughput and diagnostic depth required for sophisticated industrial network management.
The GE Fanuc IC695PBM300 serves as a high-speed communication gateway for the PACSystems RX3i platform, enabling the controller to orchestrate complex industrial PROFIBUS DP networks. By acting as the central master, this module facilitates the seamless exchange of critical process data between the host PLC and various decentralized peripheral devices. Because the module supports advanced PROFIBUS functionality, engineers can effectively integrate diverse third-party hardware into a unified automation architecture.
Enhanced Data Capacity and Communication Speeds
To accommodate data-intensive applications, the IC695PBM300 provides an extensive memory buffer capable of handling up to 3,584 bytes of input and 3,584 bytes of output data. Furthermore, the module manages up to 125 DP slave devices, where each individual slave can transmit and receive up to 244 bytes per cycle. Since network requirements vary by environment, the module offers a wide range of selectable baud rates, from a steady 9.6 kBit/s for long-distance lines up to a blistering 12 MBit/s for high-speed local synchronization.
Advanced Protocol Support and Diagnostics
In addition to standard cyclical communication, the IC695PBM300 fully supports DP-V1 acyclic messaging. This capability allows the system to perform complex tasks such as remote instrument parameterization and alarm handling without interrupting primary control cycles. Moreover, the module enhances system reliability by providing real-time diagnostic tools, including:
Comprehensive Slave Status Bit Array Tables
Detailed Network and DP Master diagnostic counters
Sync and Freeze modes for coordinated I/O updates
In-system firmware flash updates via WinLoader software
Industrial Hardware Design
The module features a robust mechanical design tailored for harsh industrial environments, operating efficiently within a temperature range of 0°C to 60°C. For physical connectivity, it utilizes a standard 9-pin Sub-D female connector, ensuring a secure and standardized interface for bus cabling. Additionally, the faceplate incorporates PROFIBUS-compliant LED indicators that provide immediate visual confirmation of network health and module status, which significantly accelerates troubleshooting procedures during commissioning.

PLC and Control Network Integration
System communication velocity and deterministic performance are regulated by the PACSystems backplane architecture. Signal integrity is preserved through high-level galvanic isolation, rated at 1500 VAC for one minute, whereby electrical noise interference is mitigated. Furthermore, firmware flash compatibility is ensured during module replacement, provided that the backplane remains energized within the specified voltage tolerances. The module is engineered for integration within both local and remote RX3i I/O racks, while support for RX7i systems is provided exclusively in distributed I/O configurations.
Frequently Asked Questions
Q: Is the module capable of being hot-swapped while the system is powered?A: Yes, the module is designed to be extracted and inserted while the RX3i backplane is energized; however, field wiring must be verified to ensure no short-circuit conditions are created during the removal process.Q: How is the signal response time managed in high-speed applications?A: A typical response time of 7 milliseconds is imposed by the hardware filter circuits. This latency is inherent and should be accounted for when high-speed pulse capture is required.
Field Installation Guidelines
The module is to be mounted onto the designated RX3i backplane slot. A mechanical click is heard when the module is fully seated.
Prior to wiring, the 24 VDC power supply must be verified for voltage stability.
Signal wires are to be connected to the terminal block. A secure, firm connection is required to prevent intermittent signal loss caused by vibration.
Shielding must be grounded at the designated earth terminal to ensure that electromagnetic interference is properly diverted.
Once the module is seated and wired, the status LEDs are to be inspected for illumination corresponding to active field device states.

Industrial Control System Performance
The IC697CGR935 relies on high-velocity backplane bus communication to ensure deterministic synchronization between redundant modules. Furthermore, firmware flash compatibility allows for controlled version updates within the Series 90-70 environment, thereby maintaining consistency across logic execution cycles. In addition, I/O density scaling is supported through the backplane interface, which enables the controller to process large datasets without exceeding defined timing constraints. Finally, Profinet and EtherNet/IP deterministic network integration requirements are managed via specific communication coprocessors when utilized in integrated automation architectures.
Frequently Asked Questions
Q: What is the failover behavior if the primary controller experiences a fault?A: In a redundant pair, the secondary controller monitors the heartbeat of the primary. Upon detection of a primary fault, the secondary transitions to the active state instantaneously to prevent interruption of the process control loop.Q: Are there specific thermal requirements for operation at ambient temperatures above 50 deg C?A: Yes. Forced air cooling is required when the operating environment exceeds 50 deg C to ensure the heat dissipation of the 80486DX4 microprocessor and internal circuitry remains within specified safe limits.
Field Installation Guidelines
Ensure the rack slot is free of debris before inserting the module to guarantee proper contact with the backplane connector.
The module must be seated flush against the rack frame and secured using the provided mounting hardware to ensure electromagnetic compatibility and grounding.
Shielded serial cables connected to the RS232 or RS485 interfaces should be grounded at the controller end to mitigate noise interference in high-EMI environments.
Upon initial power-up, verify that the 3-position switch is set to the correct mode (Run/Stop) and that status LEDs indicate valid processor health before establishing field I/O connectivity.
