GE Fanuc IC697CPX782 CPU Module Overview

The GE Fanuc IC697CPX782 is a CPU module for Series 90-70 PLCs. It uses an 80486DX4 microprocessor running at 96 megahertz clock speed. This module provides 1 MB of battery-backed RAM for program and data storage. In addition, it includes 256 KB of non-volatile memory (NV-RAM) . The IC697CPX782 supports BMA functionality in release 7.92 and later. Consequently, this CPU handles demanding control applications with ease.

Technical Specifications

The GE Fanuc IC697CPX782 delivers impressive processing power for its class. The microprocessor type is 80486DX4 with 96 MHz clock speed. Boolean function execution takes only 0.4 microseconds per operation. As a result, the CPU handles high-speed logic scanning efficiently. I/O capacity reaches 8000 analog I/O points maximum. Digital I/O capacity goes up to 12,000 points in any mix. These specifications make the IC697CPX782 suitable for large-scale automation projects.

Now consider the memory configuration in detail. Battery-backed RAM capacity is 1 MB for user programs and data tables. NV-RAM provides 256 KB of non-volatile storage. This NV-RAM retains data without battery backup. The module battery has a shelf life of 5 years at 20°C. Regular battery replacement ensures reliable operation. The IC697CPX782 supports in-system firmware upgrades for convenience.

Serial Ports & Communication

The GE Fanuc IC697CPX782 includes three on-board serial ports. Port 1 supports RS-232 communication for direct programmer connection. Port 2 and Port 3 both support RS-485 communication for multi-drop networks. A serial cable is required for interfacing with Port 1. For Ports 2 and 3, you need a converter as well. Three of the five front panel LED indicators show serial port activity status. This makes troubleshooting communication issues straightforward.

For Ethernet connectivity, additional hardware is necessary. The IC697CPX782 requires an Ethernet interface module in the PLC rack. Once installed, you can connect a programmer via Ethernet. Configuration software runs on standard computers. Communication happens over Ethernet or serial connections.

Power Requirements & Environment

The GE Fanuc IC697CPX782 draws specific current from the backplane. Nominal current is 3.1 Amps from the 5 Volts DC bus. Ensure your power supply can handle this load. Operating temperature range spans 0°C to 60°C. Store the module between -40°C and 85°C. The IC697CPX782 fits standard Series 90-70 racks. No special cooling is required within the specified temperature range.

Frequently Asked Questions (FAQ)

1. What software is needed to program the IC697CPX782?
The GE Fanuc IC697CPX782 requires Proficy Machine Edition software. Alternatively, use CIMPLICITY Logic Developer for Series 90-70 programming.

2. Can this CPU work with Release 6.0 firmware?
No. The IC697CPX782 requires release 7.92 or later for BMA support. Earlier releases may not recognize this CPU module correctly.

3. How do I connect a PC to Port 2 on the IC697CPX782?
Port 2 uses RS-485 communication. Therefore, you need an RS-232 to RS-485 converter. Connect the converter between your PC and Port 2.

4. What happens if the battery fails?
The IC697CPX782 will lose its battery-backed RAM contents. The 256KB NV-RAM data remains safe. Replace the battery immediately when the low battery LED lights up.

5. Is the IC697CPX782 compatible with Series 90-30 racks?
No. The IC697CPX782 only works with Series 90-70 racks and backplanes. Series 90-30 uses a different form factor and bus structure.
