IC697CHS790 Baseplates and Racks Series 90-70 GE Fanuc

Product Overview

Configured for structural chassis expansion and electrical interconnection in Series 90-70 backplane networks, the GE Fanuc IC697CHS790 (IC697CHS790 VME Extension Rack) provides direct physical/electrical execution. The hardware establishes a multi-slot mechanical framework and localized circuit trace bus, extending parallel processing signal distribution paths from a primary controller chassis to supplementary input/output tracking cards.

Hardware Specifications

Deterministic Networks & I/O Density Scaling

The internal tracking layers utilize predefined copper paths to stabilize backplane bus communication velocity metrics across all active slot positions. Hardware configuration options, including slot address identification settings and I/O density scaling profiles, are determined via rear jumper configurations prior to chassis anchoring. The fixed hardware traces preserve standard firmware flash compatibility parameters across connected instrumentation cards, maintaining synchronized byte transmission sequences when linking distinct baseplate segments over Profinet / EtherNet/IP deterministic networks.

Frequently Asked Questions

Q: What is the purpose of the dual 9-pin D-sub connectors situated on the side wing of the IC697CHS790 backplane?

A: These ports function as the structural interface for the serial expansion bus. One port serves as the incoming signal chain from the upstream chassis, while the second port acts as the downstream link to facilitate daisy-chaining to further extension racks.

Q: Can an IC697 central processing unit (CPU) module operate within the slots of this specific rack?

A: No. The IC697CHS790 is explicitly configured as an extension rack. The slot tracing lacks the necessary master bus arbitration links to initialize or execute instructions from a central processing unit module.

Field Installation Guidelines

• Enclosure Clearance Constraints: Bolt the structural frame directly onto a secure panel inside an enclosure with a minimum depth specification of 10 inches. Ensure clear vertical boundaries above and below the assembly to allow unrestricted thermal air convection.
• Bus Termination Boundaries: When deploying this rack as the terminal node in an expansion structure, install a physical bus terminator plug onto the unused 9-pin expansion connector to secure line impedance balance and block noise reflections.
• Shield Grounding Topology: Connect all external field sensor wire braids to the solid grounding rail fastened near the base perimeter of the metal frame chassis to isolate high-frequency electromagnetic interference.
• Module Slot Seat Alignment: Align module card edges cleanly within the plastic top and bottom guides before sliding the assembly backward. Press firmly until the multi-pin rear connector locks completely into the VME backplane socket.
