Extended speed also runs at 153.6 Kbaud with different timing parameters. Lower speeds include 76.8 Kbaud and 38.4 Kbaud for longer cable runs. The module supports the Genius protocol for distributed I/O architecture. Data exchange reaches 128 Bytes of input and output data per host in a single bus scan. Memory allocations include 256 Bytes for discrete inputs (%I) and status data. Additional memory includes 256 Bytes for discrete outputs (%Q) and fault clearing. Analog inputs (%AI) and analog outputs (%AQ) each receive 256 Bytes of memory. The IC670GBI102 supports daisy-chain topology on both primary and secondary buses.

Bus Termination and Cabling Options

The GE Fanuc IC670GBI102 provides terminating resistor connection points for bus stability. Both primary and secondary bus connections have dedicated termination points. These points connect across serial 1 and serial 2 terminals. Install terminating resistors at the start (first node) and end of the bus (last node). Resistor values include 75 ohm, 100 ohm, 120 ohm, or 150 ohm options. Pre-molded bus cables work with this bus interface module. Use catalog number IC660BLM508 which uses a 75 ohm resistor. Use catalog number IC660BLM506 which uses a 150 ohm resistor. Proper termination maintains a stable connection across the entire Genius network. The terminal block uses screw-type terminals for main bus and optional redundant bus connections. A metal grounding strip sits underneath the terminal block for proper grounding.

Dual Bus Support and Host Architecture

The GE Fanuc IC670GBI102 can be used with both single bus and dual bus setups. Dual bus configurations provide redundancy for critical control applications. The module supports CPU redundancy for high-availability systems. Hot insertion and removal of modules is supported for maintenance without shutdown. Compatible hand-held programmers include IC660HHM501 and IC693PRG300 for field configuration. Supported functions include I/O forcing, diagnostic display, and program upload/download. The IC670GBI102 interfaces with Field Control I/O modules and a host PLC or computer. Self-diagnostics run when the module starts up and check for errors. The module helps with fault reporting, analog scaling, and range selection applications.
