Product Overview
When a compact, cost-effective PLC solution is needed for small-scale automation, the GE Fanuc IC693CPU323 embedded CPU baseplate delivers reliable control without unnecessary complexity. This Series 90-30 component integrates the CPU directly onto the baseplate backplane, reducing costs while maintaining essential functionality for discrete and analog I/O applications.
The IC693CPU323 is a 10-slot embedded CPU baseplate that hosts I/O and power supply modules. Its embedded CPU uses an 80188 processor running at 10 MHz, with a typical scan rate of 0.6 milliseconds per 1K of Boolean logic. User program memory is 12 Kbytes, sufficient for many small to medium control programs. The baseplate supports up to 320 discrete I/O points, 64 words of analog input, and 32 words of analog output.
Technical Specifications Breakdown
Processor and Memory: The 80188 CPU operates at 10 MHz, providing a typical scan rate of 0.6 ms per 1K of Boolean logic. User memory is 12 Kbytes, with 340 timers and counters available. This combination handles moderate logic and sequencing tasks efficiently.
I/O Capacity: The baseplate offers ten I/O slots. Maximum discrete I/O is 320 points, with up to 160 discrete input points (%I) and 320 discrete output points (%Q) combined. Analog I/O includes 64 input words (%AI) and 32 output words (%AQ). This capacity suits applications like packaging machines or conveyor controls.
Power and Communication: The IC693CPU323 requires +5 VDC at 430 mA from the power supply module. It includes one built-in serial port that supports SNP slave and SNP-X slave protocols. Optional communication modules (Ethernet, Profibus, GBC, GCM, GCM+) can be added separately.
Environmental and Physical: Operating temperature range is 0 to 60 degrees Celsius. The baseplate has no expansion capability and does not support PCM or CCM modules. It mounts directly to a panel using provided holes.
Industry Applications
Small Machine Control: The IC693CPU323 excels in standalone machines like labelers, filling stations, or small assembly lines. Its 12 Kbytes memory and 320 discrete I/O handle sequencing and interlocks without needing a larger PLC.
Material Handling: Conveyor systems with limited zones benefit from the baseplate's 340 timers/counters for timing belt movements and counting parts. The 0.6 ms scan rate ensures responsive control.
HVAC or Pump Control: Analog I/O (64 input words, 32 output words) allows monitoring temperature or pressure sensors and controlling variable frequency drives. The embedded CPU reduces cabinet space and cost.
Installation & Setup Guidance
Mount the IC693CPU323 baseplate securely to a panel using the four corner mounting holes. Ensure adequate clearance for airflow and cable routing. Install the power supply module in the dedicated slot (one power supply slot). Connect +5 VDC power to the baseplate bus; the current load is 430 mA.
Insert I/O modules into the ten slots as needed. The baseplate does not support expansion or remote racks, so plan all I/O within the baseplate. Use the single serial port for programming or HMI communication via SNP slave or SNP-X slave protocols.
Maintenance & Reliability
The IC693CPU323 has no battery-backed clock or program interrupts, reducing potential failure points. The battery for memory backup resides in the power supply module; replace it per the power supply manual. Keep the operating environment within 0 to 60 degrees Celsius to ensure reliable operation.
Periodically inspect connections and verify that the power supply provides stable +5 VDC. The embedded CPU is soldered to the backplane and cannot be replaced separately. If the CPU fails, replace the entire baseplate.
Compatibility & Integration
The IC693CPU323 is part of the GE Fanuc Series 90-30 family. It works with standard Series 90-30 I/O modules, power supplies, and optional communication modules (Ethernet, Profibus, GBC, GCM, GCM+). It does not support PCM or CCM modules. The serial port uses SNP slave and SNP-X slave protocols for connectivity.
Selection Guide & Purchasing Advice
Before purchasing the IC693CPU323, verify your I/O count and type. This baseplate supports up to 320 discrete I/O and 64 analog input words. It is non-expandable, so ensure all I/O fits within ten slots. Confirm that your application does not require a battery-backed clock or program interrupts.
