IC693CPU313 GE Fanuc Turbo CPU Baseplate

IC693CPU313 GE Fanuc Turbo CPU Baseplate for Series 90-30

Product Introduction

The IC693CPU313 is a unique 5-slot baseplate from GE Fanuc's Series 90-30 PLC family. Unlike standard baseplates that require a separate CPU module, this unit comes with an embedded 80188 Turbo CPU operating at 10 MHz. 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). Furthermore, this baseplate supports up to five I/O modules and includes a built-in serial port for SNP and SNP-X slave protocols. Its compact design makes it an ideal choice for small to medium-sized control applications.

Key Technical Specifications

The IC693CPU313 delivers dependable performance for straightforward control tasks. Its 80188 processor runs at 10 MHz, while the scan rate is rated at 0.6 ms per 1K of Boolean logic. In terms of memory, the module provides 12 KB of user program memory for Release 7 and later versions, with 6 KB available on earlier units. For discrete I/O, it supports a maximum of 160 input points (%I) and 160 output points (%Q), combined total. Additionally, it accommodates 64 words of analog input (%AI) and 32 words of analog output (%AQ).

This baseplate draws 410 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. Moreover, the IC693CPU313 supports shift register instructions, timer functions, and counter operations. For data retention, it uses a battery-backed RAM system, supplemented by a super capacitor that maintains memory during brief power interruptions.

Memory Backup and Storage Options

The IC693CPU313 incorporates multiple layers of memory protection. The primary backup uses a battery housed within the power supply, preserving RAM contents during extended power loss. Additionally, a super capacitor provides short-term backup, taking over immediately when the power supply is removed or input power is cut off. For more secure data storage, you can also use optional EPROM or EEPROM modules, which retain data without requiring any power source. These options offer enhanced reliability for critical applications where data integrity is paramount.

Mechanical and Environmental Ratings

This embedded CPU baseplate is built for reliable operation in industrial settings. Its operating temperature ranges from 0 to 60°C (32 to 140°F), while storage temperatures may span from -40 to 85°C. The relative humidity should remain between 5% and 95%, non-condensing.

For physical installation, the IC693CPU313 provides five numbered I/O slots for various option modules. Additionally, it includes an unnumbered slot on the left edge, reserved exclusively for the power supply module. This baseplate is non-expandable, meaning it does not support additional expansion baseplates. It is also incompatible with PCM (Programmable Coprocessor Module) and CCM (CPU Communication Module) devices. Consequently, system designers should plan their I/O and communication requirements accordingly.

Installation and Configuration Guidelines

Proper setup of the IC693CPU313 requires attention to slot allocation and power supply selection. The five I/O slots can host a variety of GE Fanuc Series 90-30 modules, including discrete and analog I/O, as well as specialty option cards. However, the leftmost slot is fixed for the power supply unit only, so do not install any I/O module there.

When configuring the serial port, note that it supports SNP slave and SNP-X slave protocols exclusively. This port connects to programming devices or HMIs using the connector on the PLC power supply. For programming, you can use Logicmaster 90-30 or Proficy Machine Edition software. Furthermore, ensure that the total current draw from all installed modules does not exceed the baseplate's capacity. The IC693CPU313 draws 410 mA itself, so calculate the combined load carefully to avoid overloading the backplane.

Frequently Asked Questions

1. Is the IC693CPU313 compatible with PCM or CCM modules?
No, the IC693CPU313 does not support PCM (Programmable Coprocessor Module) or CCM (CPU Communication Module) devices. Only standard Series 90-30 I/O modules are compatible with its five slots.

2. What is the maximum user program memory available?
For units manufactured at Release 7 or later, the IC693CPU313 offers 12 KB of user memory. Earlier versions provide 6 KB. You can verify the release version by checking the module's label.

3. How does the super capacitor protect memory during power loss?
The super capacitor provides short-term backup immediately after power is removed, bridging the gap until the main battery takes over or power restores. This dual-layer system enhances data retention reliability.

4. Can I connect this baseplate to expansion racks?
No, the IC693CPU313 is a non-expandable baseplate. Therefore, it cannot connect to additional expansion or remote baseplates. Your I/O configuration must fit within the five available slots.

5. What programming software works with this CPU?
You can program the IC693CPU313 using Logicmaster 90-30, VersaPro, or Proficy Machine Edition Logic Developer. These software packages support the SNP slave protocol for serial communication.
