GE IC693CPU323 Overview
The GE IC693CPU323 is an embedded CPU baseplate from the Series 90-30 family by GE Fanuc. This unit integrates a turbo CPU directly onto the backplane, offering a cost-effective solution for small automation tasks. It features a 10-slot I/O configuration and one power supply slot, making it suitable for compact systems that do not require expansion.
Key Specifications
The IC693CPU323 operates with an 80188 processor clocked at 10 MHz. It delivers a typical scan rate of 0.6 milliseconds per 1K of Boolean logic. User memory is 12 Kbytes for releases version 7 and later, with 6 Kbytes for earlier versions. The module supports up to 320 discrete I/O points, 64 words of analog input, and 32 words of analog output. It provides 340 timers and counters and supports shift register instructions.
Communication and Connectivity
This baseplate includes one serial port that supports SNP slave and SNP-X slave protocols. Optionally, users can add modules for Ethernet, Profibus, FIP, GBC, GCM, or GCM+ protocols. Note that the IC693CPU323 does not support expansion racks, PCM, or CCM modules.
Practical Applications
Engineers choose the GE IC693CPU323 for simple, non-expandable systems where low cost and reliability are priorities. Its embedded CPU design eliminates the need for a separate processor module, reducing overall hardware complexity. The unit mounts directly to a panel using the provided holes, simplifying installation.
Power and Environmental Ratings
The baseplate requires +5 VDC at 430 mA. It operates within a temperature range of 0 to 60 degrees Celsius. The battery for memory backup resides in the power supply module, so unplugging the supply disconnects the battery, preventing time-of-day clock functionality.
Limitations to Consider
The IC693CPU323 does not support overrides, battery-backed clocks, or program interrupts. It also lacks expansion capability. These constraints make it ideal for fixed-configuration applications that do not require advanced features like remote I/O or complex interrupt handling.
Conclusion
The GE IC693CPU323 embedded CPU baseplate offers a straightforward, reliable solution for basic automation needs. Its integrated turbo CPU, ample I/O capacity, and support for common fieldbus protocols make it a valuable component in the Series 90-30 lineup. For projects where expandability is not a concern, this module provides an excellent balance of performance and cost.
