The IC697CPU780 is a central processing unit (CPU) module from the 90-70 series Programmable Logic Controller (PLC) platform, formerly manufactured by GE Fanuc and now owned by Emerson Automation. This CU module is a single-socket CPU designed for redundant controller configurations, compatible with critical applications, and requires high availability. In a redundant or hot standby configuration, the primary and secondary cpus are synchronized. As soon as the main CPU fails or switches from RUN to STOP mode, the no-disturbance control switch is automatically initiated so that there is no downtime. The IC697CPU780 mainly uses an 80386DX microprocessor with a processing speed of 16 MHz and a Boolean execution time of 0.4 microseconds per function. It is capable of handling any combination of input and output up to 12KB and analog input and output signals up to 8K. It supports floating point math calculations and other advanced instruction sets. The IC697CPU780 also features four (4) status LED indicators that describe the module as normal, operating, output enabled, and memory protection activated. Specific redundancy features of the IC697CPU780 include automatic CPU synchronization, online programming and online repair, one-scan switching, and configurable backup data sizes. Single points of failure are eliminated with redundant configuration. The module comes with an embedded RS485 communication port, a lithium battery for RAM batteries, and a clock. The battery, catalog number IC697ACC701, has a shelf life of 20 years at 10 degrees Celsius and is capable of retaining data for six (6) months.
The IC697CPU780 module is a scalable CPU module designed for hot standby CPU applications. It is available for GE Fanuc PLC, which is part of the GE PLC Series 90-70 series. The IC697CPU780 module supports redundancy features such as disturbance free switching between PLCS, CPU synchronization, 20 ms scan expansion, one scan switching, single line repair, and programming as well as memory parity and checksum. Other standard features supported by the IC697CPU780 module include a 16 MHZ 80386DX processor, 12,000 inputs and outputs, 8,000 analog I/ OS, up to 512 KB of memory, software configuration, password controlled access, and 4 status leds. System memory options include 128 KB, 256 KB, 256 KB, and 256 KB of non-volatile flash memory, or 512 KB of total system memory. The batteries that provide backup power to the system's memory have a shelf life of 68 years at 10 degrees Fahrenheit. The IC697CPU780 module draws 1.6 amps of current from the system bus. The module is compatible with 5 V DC input voltage. The IC697CPU780 module is mainly used as the CPU in the hot standby CPU redundancy system, which requires two cpus: one CPU in the main PLC and one CPU in the auxiliary PLC. The primary and backup cpus must be configured separately. One is configured as the primary CPU and the other is configured as the secondary CPU. Communication between the main PLC and the auxiliary PLC is achieved by using a bus transmitter module and a redundant communication module. The serial port on the IC697CPU780 module has a 15-pin type D connector that can be used to connect to the RS-485 serial port for establishing a serial connection to the programming computer.
