IC695PNC001 GE Fanuc RX3i Module Datasheet & Technical Manual

GE Fanuc IC695PNC001 PACSystems RX3i PROFINET Controller Module

Configured for high-speed deterministic real-time control in PACSystems RX3i platforms, the GE Fanuc IC695PNC001-AF (IC695PNC001 PROFINET Controller Module) provides direct physical/electrical execution. It handles decentralized I/O data routing over industrial Ethernet networks, arbitrates network topology constraints, and maintains synchronization profiles across remote device drops. The module incorporates four integrated ports configured as a localized switch, managing automated communications with up to 128 PROFINET I/O devices.

Hardware Specifications

PROFINET Deterministic Network Execution

The IC695PNC001-AF runs on Profinet / EtherNet/IP deterministic networks, processing cyclic and acyclic message frames down to a 1 ms update rate window. By mapping remote variables straight to the RX3i backplane, the unit optimizes I/O density scaling profiles without burdening the primary application scan cycle. Hardware-level Media Redundancy Protocol (MRP) logic allows the controller to function in ring topologies, automatically routing active frames during a single-point cable failure to prevent transmission latencies. Embedded Link Layer Discovery Protocol (LLDP) tracks exact physical cable paths, facilitating automatic device detection during configuration updates.

Frequently Asked Questions

Q: Does the IC695PNC001-AF support Hot-Swap (Bumpless Insertion) functionality within the RX3i rack?

A: Yes. The hardware architecture allows hot-swap insertion and extraction while the universal backplane is energized. This module can be removed or replaced without interrupting the power rail or stopping the execution of adjacent modules in the same rack.

Q: What are the specific speed constraints when utilizing the SFP fiber ports for PROFINET traffic?

A: The SFP slots support 100 Mbps or 1000 Mbps full-duplex operation for PROFINET communication protocols. While the copper RJ-45 ports can auto-negotiate down to 10 Mbps, that lower bandwidth limit is restricted solely to standard, non-PROFINET industrial network traffic.

Q: What is the exact function of the onboard micro-USB port during operation?

A: The micro-USB interface is used strictly as a localized diagnostic access point to run the Command Line Interface (CLI) via terminal emulation. It is designated for hardware commissioning, configuration checking, and diagnostic monitoring; it must not be used for permanent runtime network connections.

Field Installation Guidelines

• SFP Transceiver Selection Constraints: Deploy only certified SFP modules that match the physical fiber infrastructure requirements (100Base-FX for MMF up to 2 km, 1000Base-SX for MMF up to 550 m, or 1000Base-LX for SMF up to 10 km). Do not mix different speed ratings on active ring segments.
• Chassis Grounding Architecture: Ensure the RX3i chassis is bonded to the primary protective earth rail before module insertion. All shielded copper RJ-45 cables must employ fully grounded metallic plugs to bond the cable shield to the chassis housing frame.
• Ring Topology Wiring Rules: When configuring an MRP ring network, route port 1 and port 2 to opposing sides of the physical ring loop. Ensure all intermediate nodes also support the MRP protocol to guarantee deterministic failover execution times.
• Fiber Bending Radius Limits: Observe standard optical fiber installation criteria; maintain minimum bending radiuses of at least 20 times the cable diameter during pulling, and 10 times the diameter after permanent installation, to avoid optical signal attenuation or frame degradation.
