Technical Specifications

Key Features & Capabilities

The IC697BEM733D remote I/O scanner delivers deterministic, high-speed communication between the Series 90-70 CPU and distributed Genius I/O networks. Supporting up to 31 I/O blocks per scanner, this module enables extensive system expansion while maintaining scan time predictability. The Genius Bus architecture provides robust noise immunity and long-distance communication capabilities, ideal for plant-wide automation deployments. Integrated diagnostic capabilities continuously monitor bus health, module status, and communication integrity, providing real-time fault detection and simplified troubleshooting.

System Architecture & Integration

Deploy the IC697BEM733D in GE IC697CHS782 17-slot VME racks alongside powerful CPUs such as the IC697CPX935 96MHz processor or IC697CPX928-HF CPU module for maximum processing power. Power the system using the IC697PWR711H power supply module or IC697PWR722 high-capacity power supply to ensure stable operation across all I/O modules.

For advanced communication requirements, combine the IC697BEM733D with the IC697CMM742 Ethernet interface module to enable SCADA connectivity, remote monitoring, and enterprise-level data integration. The IC697PCM711 programmable coprocessor can be integrated for specialized computational tasks and protocol conversions.

Application Scenarios

Distributed Manufacturing Control: The IC697BEM733D excels in automotive assembly lines, food processing facilities, and pharmaceutical manufacturing where I/O points are geographically dispersed across production zones. Connect multiple IC660 Genius I/O blocks throughout the facility, reducing wiring costs while maintaining deterministic control response times under 10ms.

Process Industry Applications: In chemical processing, oil & gas, and water treatment facilities, the IC697BEM733D provides reliable communication in harsh electromagnetic environments. The Genius Bus protocol’s noise immunity ensures uninterrupted operation even in electrically noisy industrial settings with variable frequency drives and high-power switching equipment.

Infrastructure & Utilities: Deploy in power generation plants, wastewater treatment systems, and building automation where long-distance I/O distribution is essential. The 7,500-foot communication range with repeaters enables centralized control of geographically dispersed equipment without intermediate controllers.

Configuration & Programming

Configure the IC697BEM733D using GE Logicmaster 90-70 or Proficy Machine Edition software. The scanner automatically detects connected Genius I/O blocks during system initialization, simplifying commissioning. Each I/O block is assigned a unique bus address (1-31), and the scanner maps block data to the CPU’s I/O reference tables. Diagnostic registers provide real-time visibility into bus status, module health, and communication statistics for proactive maintenance.

Redundancy & High-Availability Solutions

For mission-critical applications requiring fault tolerance, implement dual IC697BEM733D scanners in redundant configurations. Pair with redundant CPU architectures and dual Genius Bus networks to eliminate single points of failure. The module supports hot-swap capabilities when properly configured, enabling maintenance without system shutdown. Integrate with the IC697BEM731 Genius bus controller for alternative bus topologies and expanded I/O capacity.

Installation & Wiring Guidelines

Install the IC697BEM733D in any available VME slot within the Series 90-70 rack, ensuring proper backplane connectivity. Connect the Genius Bus cable to the module’s communication port using shielded twisted-pair cable (Belden 9463 or equivalent). Terminate the bus at the final I/O block using 150-ohm termination resistors. Verify LED indicators: solid green Power LED confirms module initialization, flashing Active LED indicates bus communication, and Fault LED illuminates during communication errors or module failures.

Troubleshooting & Diagnostics

The IC697BEM733D provides comprehensive diagnostic capabilities accessible through the CPU’s diagnostic registers. Monitor bus utilization, scan time, and individual block status in real-time. Common fault conditions include bus termination errors, excessive cable length, improper block addressing, or power supply issues. Use the module’s built-in diagnostics to identify failing I/O blocks, communication timeouts, and configuration mismatches. The fault LED provides immediate visual indication of system issues requiring attention.

Common FAQs

Q: What is the maximum number of I/O points supported by the IC697BEM733D?
A: The scanner supports up to 31 Genius I/O blocks. Total I/O point count depends on block density, with typical configurations supporting 500-2,000 I/O points per scanner when using high-density blocks.

Q: Can I mix discrete and analog I/O blocks on the same Genius Bus?
A: Yes, the IC697BEM733D supports heterogeneous I/O configurations including discrete inputs/outputs, analog modules, temperature inputs, and specialty modules on the same bus network.

Q: What is the typical scan time impact of adding the IC697BEM733D?
A: Scan time impact depends on the number of I/O blocks and data density. A typical configuration with 20 I/O blocks adds approximately 5-15ms to the overall CPU scan time.

Q: Is the IC697BEM733D compatible with newer GE PACSystems platforms?
A: The IC697BEM733D is specifically designed for Series 90-70 systems. For PACSystems RX7i platforms, consider using native Genius Bus controllers or migrating to Profinet/EtherNet/IP distributed I/O architectures.

Q: How do I extend the Genius Bus beyond 7,500 feet?
A: Use Genius Bus repeaters at 2,500-foot intervals to extend total distance. Each repeater regenerates the signal, enabling multi-mile distributed I/O networks in large facilities.

Q: Can I hot-swap the IC697BEM733D during operation?
A: Hot-swap capability depends on system configuration and CPU firmware version. Consult GE documentation for specific hot-swap procedures and safety precautions to prevent data loss or system faults.
