GE IC693 (Series 90-30) Series Technical Notes
The Evolution of IC693 Architecture
The IC693 platform was introduced by GE Fanuc Automation in 1988 as a successor to the Series Six and Series Five PLC families. The original CPU module, the IC693CPU311, offered 6 KB of user memory and supported ladder diagram programming via the Logicmaster 90-30 software package running on DOS. By 1993, GE Fanuc released the IC693CPU341 with expanded floating-point math capability and peer-to-peer communications, targeting continuous process applications.
The mid-cycle refresh in 1997 introduced the IC693CPU351 and IC693CPU360, which added Ethernet TCP/IP capability natively and supported the Windows-based Proficy Machine Edition (PME) programming environment. These models also introduced the Genius Bus Controller integration, enabling the IC693 to serve as a head-end controller for distributed I/O networks across large plant footprints.
Compatibility note: IC693 modules are not electrically or mechanically interchangeable with IC695 (RX3i) modules. Baseplates, power supplies, and CPU modules are series-specific. Mixed-series configurations require the IC693CMM321 or IC695CMM004 communication bridge modules.

Quality Control for the IC693 Range
IC693 modules present specific test challenges due to their parallel backplane bus architecture and the age-related degradation patterns common in CMOS-based logic from the 1990s. DriveKNMS applies the following test protocol to all IC693 modules prior to shipment:
- Backplane bus integrity test: Each module is seated in a live IC693 baseplate and scanned for bus contention errors, address conflicts, and communication timeouts using a reference CPU at known firmware revision.
- Power rail verification: +5 VDC, +24 VDC, and −15 VDC rails are measured under load using a calibrated bench supply to confirm power supply modules meet GE specification tolerances (±2%).
- I/O point functional test: All discrete and analog I/O points are exercised through their full operating range. Analog modules are calibrated against a NIST-traceable reference standard.
- Motion controller validation (DSM314/DSM324): Axis configuration, encoder feedback loop, and servo command output are verified using a hardware-in-the-loop test fixture simulating a 4-axis servo drive network.
- Burn-in cycle: Modules are powered continuously for 48 hours at 40°C ambient to screen for early-life failures in electrolytic capacitors and SRAM components.
- Firmware revision documentation: CPU and communications modules are shipped with a documented firmware version label to prevent revision mismatch issues during installation.
