IC693CPU350-CG is the CG release of the GE Fanuc Series 90-30 CPU350. Release information identifies main firmware R10.60 and boot firmware R9.00 for this exact catalog revision.

The module is a 25 MHz 80386EX single-slot CPU with fixed 32 KB user-program memory. It supports as many as eight baseplates and uses the serial port on the Series 90-30 power supply for SNP/SNP-X communications.

• Typical Boolean scan time is 0.22 ms per 1K of logic.
• Firmware-based floating-point math is available on release 9.0 and later.
• The CPU supports periodic subroutines, overrides, a battery-backed clock, RAM and Flash storage.
• Firmware 10.60 corrected handling issues involving large smart-module initialization and DSM files; no new features were added in that release.
• Multidrop LAN operation and supported Ethernet, FIP, Profibus, Genius and communications option modules extend the base CPU.

• Back up RAM, Flash, configuration, CPU ID, status tables and the SNP ID before any firmware or hardware work.
• Record the IC693CPU350-CG label, board ID, firmware, rack layout, battery condition and every option-module revision.
• Use the CPU slot of the Series 90-30 CPU baseplate and verify the +5 V load budget.
• Restore the approved project and separately restore the SNP ID when required.
• Validate remote racks, communications modules, smart modules, retained data and machine interlocks.

• Revision-controlled support of installed Series 90-30 machines.
• Multi-rack discrete and analog control using as many as eight baseplates.
• Legacy systems using SNP/SNP-X and compatible communications option modules.
• Maintenance projects that must retain the R10.60 CG release and documented board level.
