Why the IC693CPU323 Matters for Cost-Effective Automation
In today's competitive manufacturing environment, controlling costs without sacrificing reliability is critical. The GE Fanuc IC693CPU323 offers a practical solution for small to medium control applications. This embedded CPU baseplate delivers solid performance for basic logic control while keeping hardware expenses low.
Embedded CPU designs reduce component count and simplify installation. The IC693CPU323 integrates the processor directly onto the baseplate, eliminating the need for a separate CPU module. This approach lowers upfront costs and reduces potential points of failure, making it an attractive option for budget-conscious operations.
IC693CPU323 Technical Specifications at a Glance
The IC693CPU323 is built around an 80188 processor running at 10 MHz. It provides a typical scan rate of 0.6 milliseconds per 1K of Boolean logic, ensuring responsive control for most discrete applications. The baseplate includes ten I/O slots and one power supply slot, accommodating a variety of I/O configurations.
Key specifications include:
- User memory: 12 Kbytes
- Discrete I/Os: 320 (combined inputs and outputs)
- Analog inputs: 64 words
- Analog outputs: 32 words
- Timers/counters: 340
- Serial ports: 1 (supports SNP slave and SNP-X slave protocols)
- Voltage input: 5 Volts DC
- Current input: 430 milliamps
- Operating temperature: 0 to 60 degrees Celsius
These specifications make the IC693CPU323 well-suited for applications that require moderate I/O capacity and fast logic execution. The 12Kbyte user memory provides ample space for control programs, while the 340 timers and counters support complex sequencing and timing tasks.
Real-World Applications for the IC693CPU323
The IC693CPU323 excels in small machine control, packaging lines, and material handling systems. In a typical packaging application, the baseplate can manage conveyor interlocks, sensor inputs, and actuator outputs with ease. Its 320 discrete I/O points allow for flexible configuration of inputs and outputs to match the machine's needs.

For example, a simple sorting system might use 50 discrete inputs for sensors and 40 discrete outputs for actuators. The IC693CPU323 handles this comfortably, leaving room for future expansion within the same baseplate. The 64 words of analog input capacity also enable connection to analog sensors, such as temperature or pressure transmitters, for monitoring and control.
Another common use is in HVAC control panels, where the CPU manages fans, dampers, and temperature sensors. The 0.6 ms scan rate ensures quick response to changing conditions, maintaining stable environmental control.
Compatibility and Integration Considerations
The IC693CPU323 supports SNP slave and SNP-X slave protocols via its single serial port. This allows connection to GE Fanuc programming software and operator interfaces. For network integration, optional modules for Ethernet, Profibus, and GCM can be installed, providing connectivity to plant-wide systems.
It is important to note that the IC693CPU323 does not support expansion baseplates or remote racks. This limitation makes it ideal for standalone applications where the I/O count is known and fixed. Additionally, the baseplate does not support PCM or CCM modules, so those advanced communication options are not available.
When planning your system, verify that the required I/O count and communication needs fit within the IC693CPU323's capabilities. For many small to medium applications, this baseplate provides a cost-effective and reliable solution.
Business Value: Lower Cost, Reliable Performance
Choosing the IC693CPU323 can reduce total cost of ownership. The embedded design eliminates the need for a separate CPU module, saving money on hardware. Additionally, the baseplate's robust construction and proven Series 90-30 platform ensure long service life, minimizing downtime and maintenance costs.

With a typical scan rate of 0.6 ms, the CPU keeps processes running efficiently, reducing cycle times and improving throughput. The 12Kbyte memory is sufficient for most control programs, avoiding the need for expensive memory expansion.

Frequently Asked Questions
What is the difference between an embedded CPU and a modular CPU?
An embedded CPU, like the one in the IC693CPU323, is soldered onto the baseplate and cannot be removed or upgraded. Modular CPUs are separate modules that can be replaced or upgraded independently. Embedded CPUs are typically lower cost and simpler, while modular CPUs offer more flexibility and higher performance.
Can the IC693CPU323 be expanded with additional I/O?
No, the IC693CPU323 does not support expansion baseplates or remote racks. It is designed for standalone applications with a fixed I/O count. The baseplate provides ten I/O slots, which can accommodate a variety of discrete and analog modules up to the maximum limits.
What communication protocols does the IC693CPU323 support?
The IC693CPU323 has one serial port that supports SNP slave and SNP-X slave protocols. For other protocols like Ethernet or Profibus, you can install optional communication modules, but these are not included with the baseplate.
What is the maximum number of discrete I/O points?
The IC693CPU323 supports up to 320 discrete I/O points, which can be configured as inputs or outputs. The maximum number of discrete input points is 160, and the maximum number of discrete output points is 320, but the total combined cannot exceed 320.
Does the IC693CPU323 have a battery-backed clock?
No, the IC693CPU323 does not have a battery-backed clock. The battery for memory backup is located in the power supply module, and unplugging the power supply disconnects the battery from the memory circuits. This design prevents the use of a time-of-day clock.
