GE IC697CGR772 90-70 Series CPU Module

Processor Performance: Equipped with a 96MHz 80486 DX4 processor, supporting 32-bit floating-point operations, it can efficiently handle complex control tasks, with a Boolean execution time of 0.4 microseconds per Boolean function.

Redundancy Features: Supports hot standby redundancy and non-disturbance switching. When the main CPU fails, the standby CPU can seamlessly take over, ensuring continuous system operation and reducing downtime.

I/O Capability: Can support up to 2048 discrete I/O points and 8K analog I/O points, meeting the needs of large-scale industrial automation systems for processing a large number of input and output signals.

Memory Configuration: Equipped with 512KB battery-backed CMOS RAM, which can store critical data and programs for up to 6 months without external power supply. The battery type is IC697ACC701, which is easy to replace.

Communication Interfaces: Has three serial ports, one of which is RS-232, and the other two are RS-485, supporting SNP protocol communication. It can also support network operations through an optional Ethernet module to enhance connectivity.

Status Indicators: The module is equipped with 7 LED indicators, including running, normal, low battery, and communication status, which can feedback the system health and operation status in real-time, facilitating user monitoring and troubleshooting.

Programming Methods: Supports standard PLC programming languages such as Relay Ladder Logic (RLL) and Control Function Diagram (CFD), allowing flexible selection of programming methods according to different industrial control needs.

Mechanical Characteristics: It is a single-slot module, conforming to the standard rack size of the GE Fanuc 90-70 series, and is easy to install.

Rotary Fan Control: In a certain rotary fan control system, the 90-70 dual-machine hot standby system from GE Fanuc of the United States was selected, with the IC697CGR772 as the PLC master station CPU module. Its 96MHz main frequency and 1M user memory can meet the system requirements. During normal operation, one CPU controls the system, and the other serves as a standby. When a problem occurs in the main rack, it can switch to the standby rack without disturbance, ensuring the normal operation of the system and allowing operators to calmly maintain the problematic rack.

Real-time Control of Generator Sets: In the field of power production, the stable operation of generator sets is crucial. The IC697CGR772 can be applied to the real-time control system of generator sets. With its dual-bus architecture and hot standby function, when the main CPU fails, the standby CPU can quickly and seamlessly take over, ensuring that the control signals of the generator sets are not interrupted, maintaining the stability of the power generation process, and reducing power outages caused by faults.

Chemical Reactor Control: In chemical production, the control accuracy of parameters such as temperature and pressure of the reactor is high, and long-term shutdown is not allowed. The IC697CGR772 can be used in the reactor control system, which accurately controls the feeding, heating, stirring and other operations of the reactor by collecting sensor data in real-time. Its redundant design can automatically switch to the standby link or CPU when the bus or CPU fails, preventing production accidents caused by control interruption and ensuring the safety and stability of chemical production.

Automobile Manufacturing Production Line Control: The automobile manufacturing production line includes many processes and equipment, which have high requirements on the reliability and real-time performance of the control system. The IC697CGR772 can be used to coordinate the operation of various links in the production line, such as the equipment control of body welding, parts assembly and other processes. By cooperating with various I/O modules, it can receive sensor feedback information in real-time and accurately control the actions of robotic arms, conveyors and other equipment. Even if a CPU module fails, it can ensure the continuous operation of the production line through the hot standby function, reducing downtime and improving production efficiency.

Rail Transit Signal Control: In the rail transit system, the Automatic Train Control (ATC) system has extremely high requirements on the reliability of signal transmission and control. The IC697CGR772 can be applied to the ATC system, responsible for processing and transmitting various signal commands, such as train speed control and signal display. Its dual redundancy feature can ensure accurate and timely sending and receiving of signals under any circumstances, ensuring the safety of train operation and avoiding traffic accidents caused by control system failures.
