IC693CPU323 GE Fanuc Embedded Turbo CPU

IC693CPU323 GE Fanuc 10-Slot Turbo CPU Baseplate for Series 90-30

Product Introduction

The IC693CPU323 is a 10-slot embedded Turbo CPU baseplate from GE Fanuc's Series 90-30 PLC family. This unit integrates an 80188 processor running at 10 MHz directly onto the baseplate, with memory chips soldered firmly to the backplane. Its typical scan rate reaches 0.6 milliseconds per 1K of Boolean logic, ensuring responsive control execution. For user programs, it offers 12 KB of memory (6 KB for pre-Release 7 units). This baseplate supports up to 320 discrete I/O points, 64 analog input words, and 32 analog output words. Additionally, it includes 340 timers and counters, along with shift register instructions. However, this unit does not support expansion racks, PCM, or CCM modules, making it ideal for smaller, cost-sensitive applications.

Key Technical Specifications

The IC693CPU323 delivers dependable performance for compact control systems. Its 80188 processor operates at 10 MHz, while the scan rate is rated at 0.6 ms per 1K of Boolean logic. For memory, the module provides 12 KB of user program memory for Release 7 and later versions, with 6 KB available on earlier units. In terms of I/O capacity, it supports up to 320 discrete input and output points in any combination. Moreover, it accommodates 64 words of analog input (%AI) and 32 words of analog output (%AQ).

This baseplate draws 430 mA at 5 VDC from the backplane. It features a single serial port that supports SNP slave and SNP-X slave protocols, using a connector located on the PLC power supply. Furthermore, the IC693CPU323 supports 340 timers and counters, as well as shift register instructions. Optional communication modules are available for Ethernet, Profibus, FIP, GBC, GCM, and GCM+ protocols.

Memory Backup and Storage Options

The IC693CPU323 uses a battery-backed RAM system for user program storage. The backup battery resides in the power supply module, so unplugging the power supply disconnects the battery from the memory circuits. For more permanent data retention, you can install optional EPROM or EEPROM modules. These non-volatile memory options retain data without requiring any power source. However, note that this baseplate does not include a battery-backed real-time clock. Consequently, time-stamping functions are not available on this unit.

Mechanical and Environmental Specifications

This embedded CPU baseplate is built for reliable operation in industrial environments. Its operating temperature ranges from 0 to 60°C, while storage temperatures span from -40 to 85°C. Relative humidity should remain between 5% and 95%, non-condensing. The IC693CPU323 supports panel mounting through dedicated mounting holes on the baseplate.

For physical installation, the baseplate provides ten I/O slots for various Series 90-30 modules. The power supply occupies a dedicated position, and the serial port connector is accessible on the power supply unit itself. Because this unit lacks an expansion connector, you cannot attach additional racks. Therefore, all I/O modules must fit within the ten available slots. Additionally, the IC693CPU323 is not compatible with PCM (Programmable Coprocessor Module) or CCM (CPU Communication Module) devices.

Installation and Configuration Guidance

Proper setup of the IC693CPU323 requires careful slot planning and software configuration. The ten I/O slots can host a mix of discrete and analog modules, specialty cards, or optional communication interfaces. However, since expansion is not supported, ensure that your total I/O count does not exceed the baseplate's capacity. Specifically, you can use up to 320 discrete points, 64 analog inputs, and 32 analog outputs in any combination.

For programming, you can use Logicmaster 90-30 (DOS-based), VersaPro (Windows-based), or Proficy Logic Developer Machine Edition. The built-in serial port provides a direct connection to a personal computer running these software packages. Alternatively, you can install optional communication modules for Ethernet or fieldbus connectivity. Additionally, always verify that the total backplane current draw from all installed modules, including the IC693CPU323 itself, stays within the power supply's capacity.

Frequently Asked Questions

1. Does the IC693CPU323 support expansion or remote racks?
No, the IC693CPU323 does not include an expansion connector. Therefore, it cannot connect to additional expansion or remote racks. Your I/O configuration must fit entirely within the ten available slots.

2. What is the maximum user program memory available?
For units manufactured at Release 7 or later, the IC693CPU323 offers 12 KB of user memory. Earlier versions provide 6 KB. You can verify the release version by checking the module's label.

3. Is the IC693CPU323 compatible with PCM or CCM modules?
No, the IC693CPU323 does not support PCM (Programmable Coprocessor Module) or CCM (CPU Communication Module) devices. Only standard Series 90-30 I/O modules and select communication option modules are compatible.

4. Does this baseplate include a battery-backed real-time clock?
No, the IC693CPU323 does not have a battery-backed clock. The backup battery is located in the power supply, and unplugging the power supply disconnects the battery from the memory circuits, which would interfere with time-of-day clock settings.

5. What programming software works with this CPU?
You can program the IC693CPU323 using Logicmaster 90-30 (DOS-based), VersaPro Professional Edition, or Proficy Logic Developer Machine Edition. All of these support the SNP slave serial protocol.
