GE IC660ELB912 MicroGENI Daughterboard

The GE Fanuc IC660ELB912, also cataloged as the IC660ELB912 MicroGENI Daughterboard, operates as a dedicated hardware component for industrial network interfacing, data register mapping, and multi-node fieldbus telemetry management within PC Interface Module (PCIM) architectures. The specialized coprocessor card mounts natively at the hardware tier onto host PCIM parent boards to establish a deterministic control and monitoring gateway between IBM PC/AT/XT compatible host computers and distributed Genius I/O networks.

Hardware Specifications

Industrial Control & Drive Communications

• Backplane Bus Communication Velocity Licences and Shared RAM Mapping The daughtercard utilizes a high-speed 16 Kbyte shared RAM window that maps fieldbus state registers directly into the host PC memory map. This dual-port hardware architecture allows the onboard 6303 microprocessor to handle real-time background messages, token-passing routines, and I/O scan updates independently of the host PC operating system processing loop.
• I/O Density Scaling and Dual-Channel Bus Redundancy The daughtercard expands system network density by executing global data exchanges with up to 30 distinct Genius devices per link. When configured in a dual-channel host PCIM assembly (IC660ELB922) utilizing two separate IC660ELB912 cards, the modules can be cross-strapped to the same physical fieldbus layer or mapped to independent subnetworks, scaling local data assembly arrays while maintaining synchronized network baud rates via on-board DIP switches.
