IC697BEM731 GE Fanuc Series 90-70 Genius Bus Controller

Product Overview

The IC697BEM731 is a single-slot Genius Bus Controller Module developed by GE Fanuc for the Series 90-70 PLC platform. This module acts as the core communications interface for managing a Genius I/O distributed system, enabling high-speed, deterministic data exchanges between the central processor and field devices.

Key Advantages

• Dedicated Utility Ports: Features 1 standard Bus Controller port alongside 1 dedicated Hand-Held Terminal (HHT) port for convenient on-site diagnostics and setup.
• Flexible Data Rates: Supports multiple baud rate configurations (153.5K, 76.8K, or 38.4K baud) to accommodate varying network topologies and line conditions.
• High Network Density: Manages up to 30 distinct devices per channel to provide wide-reaching network scalability.

Technical Specifications

Quick Installation Tips

• Completely isolate and shut off the Series 90-70 backplane power before inserting this single-slot module.
• Always deploy Belden 9182 or an approved equivalent serial cable to meet factory signaling and shielding prerequisites.
• Ensure that the collective count of network links does not exceed the maximum threshold of 30 devices per channel.

Technical FAQs

Q1: What is the purpose of the Hand-Held Terminal port?

A1: It permits direct plug-in access for an external Genius HHT device, allowing engineers to force I/O points, monitor states, and adjust network metrics without a separate computer link.

Q2: How does data transmission speed alter network limitations?

A2: Selecting lower baud rates (like 38.4K or 76.8K baud) permits much longer drop-line distances, whereas the 153.5K baud rate yields the fastest system refresh cycle for shorter cabling paths.

Q3: Does the 1.3 Amps load imply special power demands?

A3: Yes. Ensure that the rack power supply unit provides ample overhead on its 5.0 Volt DC rail to accommodate this 1.3A consumption along with other concurrent modules.
