Description

The General Electric IC697CPM790 is a high-performance Series 90-70 64 MHz, 32-bit floating-point central processing unit designed specifically for critical control applications such as Emergency Shut-Down (ESD), fire and gas systems, and Triple Modular Redundancy (TMR) architectures. This single-slot CPU integrates 1 Mbyte of battery-backed CMOS RAM, providing 512 Kbytes dedicated to user application programs and data.

Equipped with an 80486DX2 microprocessor, the IC697CPM790 ensures rapid execution times of 0.4 microseconds per Boolean function. Operating within the Series 90-70 rack-mounted backplane environment utilizing the VME C.1 standard format, the module communicates seamlessly with standard I/O and smart option modules. It requires integration with a standalone C program containing TMR operating and autotest routines to function within high-reliability system configurations.

Features

Single-slot Series 90-70 central processing unit with 64 MHz 80486DX2 microprocessor and hardware floating-point math coprocessor
1 Mbyte of battery-backed CMOS RAM memory board integrated directly onto the module, with 512 Kbytes allocated for user application programs
Flash memory for operating system firmware storage, allowing in-system updates via the serial port without module disassembly
Supports up to 12K discrete inputs/outputs and 8K analog inputs/outputs in simplex mode, alongside 2,048 voted discrete inputs/outputs and 1,024 voted analog inputs
Three-position RUN/STOP operation mode switch and front-panel memory protect keyswitch for enhanced security
Four diagnostic status LEDs providing real-time indication of module health, run status, output enablement, and memory protection state
RS-422/RS-485 compatible serial port for programmer attachment and system communications

Applications

Emergency Shut-Down (ESD) safety systems
Industrial fire and gas detection architecture
Triple Modular Redundancy (TMR) critical control loops
High-availability process automation and discrete manufacturing

FAQ

What are the primary applications for the General Electric IC697CPM790 CPU?

The General Electric IC697CPM790 is specifically engineered for critical control applications that demand high reliability, such as Emergency Shut-Down (ESD) safety systems and industrial fire and gas detection. This single-slot module also supports Triple Modular Redundancy (TMR) architectures and high-availability process automation. It operates efficiently within the Series 90-70 rack-mounted backplane environment utilizing standard VME C.1 formats.

What is the processing performance and memory capacity of the General Electric IC697CPM790?

Powered by a 64 MHz 80486DX2 microprocessor with a 32-bit floating-point math coprocessor, the General Electric IC697CPM790 delivers rapid execution times of 0.4 microseconds per Boolean function. The unit includes 1 Mbyte of total battery-backed CMOS RAM, providing 512 Kbytes specifically allocated for user application programs and data storage. Additionally, it features onboard flash memory for convenient firmware storage and in-system updates via the serial port.

What I/O capacity does the General Electric IC697CPM790 support in a system?

In standard simplex mode, the General Electric IC697CPM790 supports up to 12,000 discrete inputs/outputs and 8,000 analog inputs/outputs. When deployed in high-integrity redundant configurations, it can handle 2,048 voted discrete inputs/outputs and 1,024 voted analog inputs. This robust capacity makes it well-suited for large-scale industrial automation and complex discrete manufacturing environments.

How should the General Electric IC697CPM790 be installed within a rack?

When installing the General Electric IC697CPM790, you must ensure that all rack power is completely switched off before inserting or removing the module. The unit is designed to be installed exclusively in slot 1 of rack 0 utilizing the VME C.1 standard card-edge connector. Installers must also connect the IC697ACC701 lithium backup battery prior to initial operation to ensure proper CMOS RAM data retention during power loss.

What are the environmental and power requirements for the General Electric IC697CPM790?

The General Electric IC697CPM790 draws a nominal current of 3.3 Amps from the 5V backplane bus during standard operation. It functions within an operating temperature range of 0 to 60 degrees Celsius when supported by at least 70 CFM of forced air cooling. Without forced air, the maximum operating temperature is restricted to 40 degrees Celsius to prevent thermal degradation.
