GE Fanuc IC695PBS301 PACSystems RX3i Profibus Slave Module

Product Description

The GE Fanuc IC695PBS301, also cataloged as the IC695PBS301 Profibus Slave Module, operates as a dedicated hardware component for deterministic fieldbus slave communication within PACSystems RX3i backplane platforms. It facilitates cyclic data exchanges between an external Profibus DP master controller and the local RX3i central processing unit, transferring up to 244 bytes of input data and 244 bytes of output data per network scan cycle.

Hardware Specifications

Backplane Bus Communication Velocity and Network Integration

The architecture of the module uses an internal high-speed PCI backplane bus system to map network data tables straight into the host hardware processor registers. Network transmission velocities scale from 9.6 kbps up to 12 Mbps, matching the physical layer constraints defined by the active master node. Real-time diagnostic LEDs mounted on the front faceplate display network communication health, system status, and device configuration validation in compliance with standard hardware firmware flash profiles.

Frequently Asked Questions

Q: Does this module support network configuration changes via hot-swap procedures?

A: No. The RX3i system configuration requires a standard download sequence while the CPU is in a controlled state. Physical insertion or removal under backplane tension must follow the generic hot-swap restrictions specified for the RX3i rack to prevent internal bus noise.

Q: How are network station addresses configured for this component?

A: The slave station address is assigned via the software configuration utility and stored inside the non-volatile memory of the module. There are no physical hardware dual in-line package switches on the faceplate assembly.

Field Installation Guidelines

• Backplane Insertion: Verify that the RX3i rack alignment tracks match the upper and lower module grooves before securing the locking mechanism. Tighten the module screws to ensure positive ground contact.
• Shield Grounding: The Profibus cable shield must hook into the metallic shell of the 9-pin D-sub terminal connector to maintain an effective path to the protective earth grid.
• Bus Termination: Active termination is mandatory at both physical extremities of the Profibus network segment. If this module is the terminal node on the bus segment, turn the external terminator selector switch on the D-sub connector plug to the ON position.
