GE Fanuc IC695PBM300 PACSystems RX3i PROFIBUS Master Module
The GE Fanuc IC695PBM300, also cataloged as the IC695PBM300 PROFIBUS Master Module, operates as a dedicated hardware component for high-speed distributed communication within PACSystems RX3i platforms. The module executes deterministic data exchange between an RX3i central processing unit and up to 125 PROFIBUS DP slave devices, including remote I/O units, variable frequency drives, and process instrumentation. Operating directly across the RX3i PCI backplane bus, it manages real-time transmission blocks while maintaining diagnostic registers for network integrity.

Backplane Bus Communication Velocity and Deterministic Networks
The IC695PBM300 interfaces directly with the RX3i PCI backplane bus to synchronize network data arrays without introducing processing latency to the local CPU. This tight bus integration optimizes I/O density scaling by supporting up to 3584 bytes of input and 3584 bytes of output memory data simultaneously. The hardware architecture ensures deterministic communication cycles when executing cyclic DP-V0 I/O transfers, while concurrently processing acyclic DP-V1 parameters, alarms, and diagnostic messages. This communication speed prevents latency propagation across adjacent deterministic industrial networks.
Frequently Asked Questions
Q: What are the minimum system firmware and software requirements for the IC695PBM300?
A: The host PACSystems RX3i CPU must run firmware version 2.9 or later. Configuration and programming require Machine Edition Logic Developer PLC version 5.0 Build 3227 SP2 or later, or a compatible version of the PLC C Toolkit (Version 4.00 Build 50A1 or later) for custom C code applications.
Q: Does the module support Direct I/O (DOIO) function block execution?
A: No. DOIO functionality is not supported within the embedded PROFIBUS interface structure of this module. Executing a DOIO function block targeting this interface causes the master to return an execution error.
Q: How is the module firmware upgraded or serviced?
A: Firmware flash compatibility allows field upgrades directly through the host RX3i CPU backplane interface utilizing the WinLoader serial/ethernet utility. This eliminates the need for manual chip replacement or external hardware programmers.
Field Installation Guidelines
- Chassis Insertion: Ensure power to the RX3i universal backplane is isolated before installing the module. Slide the board into the designated single-slot position on the PCI bus until the top and bottom captive fasteners align with the chassis frame, then torque the screws to secure physical electrical contact.
- Bus Cable Termination: The PROFIBUS RS-485 network must be terminated properly at both physical ends of the segment. When the IC695PBM300 is positioned at an endpoint, the DB9 connector termination switch must be set to the active "ON" position to engage internal resistor networks.
- Shield Grounding Protocol: Use shielded twisted-pair cable rated for PROFIBUS networks. Strip the cable jacket at the entry bulkhead and secure the exposed braided copper shield to the metal chassis earth grounding clamp to prevent high-frequency electro-magnetic interference from interrupting differential signaling.
