GE IC600 Series Technical Notes

The Evolution of IC600 Architecture

The IC600 platform progressed through three identifiable hardware generations. The first generation (circa 1982–1987) established the physical backplane standard: a passive bus carrying a 16-bit parallel data path, dedicated I/O addressing lines, and a +5 VDC / ±15 VDC power distribution rail. CPU modules in this era — including the IC600CB501 and IC600CB502 — executed ladder logic at scan rates of 5–20 ms depending on program size, with memory capacities of 4K to 16K words of CMOS RAM backed by lithium battery.

The second generation (circa 1987–1993) introduced enhanced CPU modules (IC600CB503, IC600CB504) with expanded memory (up to 64K words), floating-point coprocessor options, and the Genius Bus communications adapter (IC600BF900) that enabled distributed I/O over a shielded twisted-pair serial bus at 153.6 kbps. This generation also standardized the fault-tolerant power supply form factor (IC600PS501, IC600PS502).
