The IC697CPU731 is a single-slot CPU designed for Series 90-70 PLC systems. It's a high-performance central processing unit (CPU) that enables real-time control of machines, processes, and material handling systems. With its 12 MHz, 80C186 microprocessor, the CPU731 supports up to 512 mixed inputs and outputs, as well as 8K analog I/O. This CPU ensures fast processing speeds, capable of handling boolean operations in just 0.4 microseconds, making it an excellent choice for demanding industrial applications.

Entry-Level Overview
If you're just getting started with industrial control systems, the IC697CPU731 is a good option for reliable and high-speed control. Think of it as the brain of your PLC system—it handles all the calculations, makes sure inputs and outputs are working properly, and keeps the whole system running smoothly. This CPU takes up only one slot in your rack, so it's a space-saver, too. And don’t worry, it’s easy to program, whether you’re using MS-DOS or Windows-based software.

Technical Details

    Single Slot CPU: The IC697CPU731 occupies only one slot in the IC697 rack, making it compact yet powerful.
    Input/Output Support: It can handle up to 512 mixed inputs and outputs, and supports up to 8K analog I/O.
    Processing Speed: With a 12 MHz 80C186 microprocessor, the CPU delivers 0.4 microseconds per boolean function, ensuring fast and efficient performance.
    Memory: The CPU features 32 Kbytes of battery-backed CMOS memory, ensuring your program and data are safe in case of power outages.
    Programming: This CPU can be programmed via MS-DOS or Windows-based software through Ethernet TCP/IP or the built-in SNP port. It allows remote access and configuration for easy setup and maintenance.
    Backup Power: A built-in lithium battery backs up memory and operates the clock, so even during power loss, the CPU can retain data.
    Status Indicators: The module features three status LEDs to indicate whether the module is functioning correctly, whether the CPU is running, and whether the outputs are enabled or disabled.
    Security: It offers password-controlled access to prevent unauthorized changes.
    VME Standard Compatibility: This CPU communicates over the VME C.1 standard format and supports various IC660/IC661 and IC697 I/O products.

Key Features:

    12 MHz microprocessor for fast processing
    512 digital I/O points, up to 8K analog I/O
    32 Kbyte battery-backed memory
    Configurable data and program memory
    Ethernet TCP/IP programming support
    No DIP switches or jumpers needed
    Battery-backed calendar clock

Installation and Setup
The IC697CPU731 is designed for easy installation in the leftmost slot of an IC697 rack (Slot 1). Before you start, make sure the power is off. Once it's slotted in, you’ll connect the battery for backup and flip the toggle switch to the "STOP" position. After turning the power back on, the top LED will blink during startup diagnostics. Once everything’s good to go, the top LED will stay lit, and you’ll be ready to program it. The three-position toggle switch on the front lets you control the operational modes, and the status LEDs keep you informed about the system’s state.

Programming Options
You can program this CPU using a parallel connection (for MS-DOS users) or through the Ethernet TCP/IP interface. The serial port provides RS-422 compatibility, allowing for easy communication with the programmer’s serial attachment. In Ethernet setups, you’ll need to configure the IP address before connecting the PLC and programmer.

If you're managing an industrial control system, the IC697CPU731 is a powerful and reliable solution that won't disappoint. It's easy to install, configure, and maintain. The flexible memory options and high-speed processing make it ideal for handling complex machine controls or process automation tasks. With its robust feature set and dependable performance, it's a solid investment for any control system. As always, make sure to back up your configurations and regularly check the battery status for uninterrupted operation.
