GE Fanuc designed this CPU module for the Series 90-30 PLC systems. The IC693CPU340 uses an 80C188XL series microprocessor running at 20 Megahertz . The module supports 512 input points and 512 output points for discrete control. Total register memory measures 19.9 kilobytes , while maximum user program memory reaches 32 kilobytes . Therefore, this CPU suits medium-sized control applications requiring reliable ladder logic execution.

Technical Specifications

Processor and Memory

The IC693CPU340 operates with a 20 Megahertz clock speed. The microprocessor is the 80C188XL , a proven industrial processor. User program memory provides 32 kilobytes of storage for ladder logic and control programs. Register memory offers 19.9 kilobytes for data storage. The CPU uses flash memory for user program storage, which retains programs even after power loss.

I/O Capacity

The module supports 512 discrete input points and 512 discrete output points . For analog control, the IC693CPU340 supports 12 sixteen-channel analog input modules . It also supports 30 two-channel analog voltage output modules . For current output, the module supports 15 two-channel current output modules . Additionally, the CPU supports 32 eight-channel output modules and 32 high-speed counter modules . For specialized processing, the module supports 16 I/O processor modules .

State Logic Processor Compatibility

The IC693CPU340 works with the State Logic Processor (SLP) module. The SLP module installs in a Series 90-35 PLC system to provide real-time multi-tasking control for machine applications. However, the SLP module requires a CPU from the 331, 340, or 341 series. Therefore, the IC693CPU340 serves as a compatible host for SLP installations.

Programming Software Access

Flash memory operations are accessible from the Program Utilities Function menu . Users can also access these functions from another Program Utilities screen in the software. Compatible programming software includes Logicmaster 90-30, 20, or Micro . These tools provide read, write, and verify functions for program management.

Limitations

The IC693CPU340 does not support floating point math . For applications requiring floating point calculations, consider a newer CPU model. This limitation affects certain mathematical operations and data handling.

Power Requirements

The current consumption measures 490 milliamps at 5 Volts DC . This power draws from the backplane through the module's connectors. Ensure your power supply can deliver adequate current for this CPU plus all installed I/O modules.

CPU Architecture

The IC693CPU340 is a modular CPU designed for the Series 90-30 backplane. GE Fanuc also manufactures embedded CPUs, which are comparatively more cost-effective. However, embedded CPUs offer less processing power than modular CPU modules like the IC693CPU340 .

Installation Guide

Follow these steps to install your IC693CPU340 correctly.

1. Power Down the System: Disconnect power from the Series 90-30 rack. This prevents electrical damage during installation.

2. Select the Slot: Choose the appropriate slot for the IC693CPU340 . For most configurations, install the CPU in the leftmost slots.

3. Insert the Module: Align the IC693CPU340 with the slot guides. Push firmly until the module seats into the backplane connector.

4. Secure the Module: Tighten the retaining screws at the top and bottom. This secures the CPU module in place.

5. Apply Power: Restore power to the Series 90-30 rack. Verify that the CPU powers up without errors.

6. Connect Programming Software: Use Logicmaster 90-30 software to connect to the IC693CPU340 . Establish communication through the programming port.

7. Download User Program: Transfer your ladder logic program to the 32 KB user memory. Use the read/write/verify functions from the Program Utilities menu.

8. Test Operation: Run diagnostic checks to confirm all functions work properly. Verify I/O points respond correctly.
