The IC697CPX772 is a 96 MHz, 32-bit Central Processing Unit (CPU) with 512 Kbyte battery-backed RAM memory, designed for industrial automation systems. This CPU offers advanced programming and communication features, making it suitable for real-time control of machines, processes, and material handling systems.

Key Features

    Processor: 96 MHz 80486DX4 microprocessor.
    Memory Capacity: 512 Kbyte battery-backed CMOS RAM and 256 Kbyte non-volatile user flash memory.
    I/O Capacity: Supports 2K inputs and outputs and up to 8K analog I/O.
    Processing Speed: Executes Boolean logic in 0.4 microseconds.
    Programming: Configurable via MS-DOS or Windows software, communicates over Ethernet TCP/IP or SNP port.
    Battery-Backed Calendar Clock: Retains date and time even during power loss.
    Memory Protection: Protects configuration and data with keyswitch or password.
    Status LEDs: Seven LEDs indicate CPU status and operation modes.
    Firmware Upgrades: Supports in-system firmware upgrades via flash memory.

Functions

The IC697CPX772 is a single-slot PLC CPU that supports floating point calculations. It is programmed and configured using MS-DOS or Windows-based software, providing real-time control of machines, processes, and material handling systems. The CPU communicates with I/O and option modules via the VME C.1 Standard backplane.

Supported modules include LAN Interface modules, Programmable Coprocessor, Bus Controller for IC660/IC661 I/O, and all IC697 discrete and analog I/O modules.

Installation and Operation

    The CPU is installed in Slot 1 of Rack 0.
    Controlled by a three-position RUN/STOP switch or remotely via attached programming software.
    The CPU status, serial port activity, and operation modes are indicated by seven LEDs located on the front of the module.
    After verifying the program, the switch can be set to the desired operation mode: RUN WITH OUTPUTS ENABLED, RUN WITH OUTPUTS DISABLED, or STOP.

Memory and Expansion

    512 Kbyte battery-backed RAM stores program and data.
    An additional 256 Kbyte of non-volatile flash memory is available for user data storage.
    The operating system is stored in flash memory, allowing for firmware updates without disassembling the module or replacing EPROMs.

Serial and Ethernet Communication

The IC697CPX772 has three independent serial ports. These ports are used to interface with a programming computer or other serial devices. Two ports are RS-485 compatible, and one is RS-232 compatible. For Ethernet TCP/IP communication, an Ethernet Interface module such as the IC697CMM741 or IC697CMM742 is required.

Cooling Requirements

The IC697CPX772 requires forced air cooling for operation in ambient temperatures above 50°C. Fan assemblies, such as IC697ACC721/724, can be mounted directly on the rack for effective cooling.

The IC697CPX772 is a high-performance, single-slot CPU designed for industrial automation applications requiring floating point calculations and real-time control. With 512 Kbyte RAM, extensive communication options, and flexible memory configurations, it offers robust and reliable control for a wide range of industrial systems.
