Functional Description
IC697CPU771 is an expandable CPU module developed by GE Fanuc. It is a high-performance, expandable Programmable Logic Controller (PLC) CPU manufactured by GE Automation and Controls. Designed for real-time control of industrial machinery and processes, this single-slot CPU is integrated into a rack-mounted backplane, enabling communication with various I/O and smart option modules.
Features and Capabilities
- Advanced Processing Power: 12MHz 80C186 microprocessor, which is capable of executing Boolean functions in as little as 0.4 microseconds. This rapid processing capability ensures that industrial systems can operate with high efficiency and responsiveness, allowing for timely decision-making and control in dynamic environments. The fast execution times make it suitable for applications that demand quick reaction to changing conditions, such as assembly lines and automated manufacturing systems.
- I/O Support and Compatibility: Supports an extensive range of I/O configurations, accommodating up to 8K analog I/O and a mixed configuration of up to 2K discrete I/O. This flexibility allows users to tailor the CPU to meet the specific requirements of their applications. Additionally, the module is compatible with various smart option modules, including LAN interface modules, coprocessors, and communications modules. It also supports IC660 and IC661 bus controller I/O modules, enhancing its connectivity and expandability within an industrial control system.
- User-Friendly Configuration: Configuring is streamlined and user-friendly. It can be set up using software that runs on MS-DOS, Windows 95, or Windows NT. Unlike some older devices that require the manual setting of DIP switches or jumpers for programming, allows for configuration management through a serial, parallel, or Ethernet interface connected to a computer. This modern approach simplifies the configuration process and minimizes the likelihood of user error. Furthermore, built-in password protection ensures that device settings remain secure and are only accessible to authorized personnel.
- Memory Expansion and Management: The CPU module relies on a memory expansion board to store user programs and data, with support for up to 512 kilobytes of memory. This additional memory capacity enables complex programming and data handling, essential for advanced control applications. The memory is maintained by an on-board CMOS battery, ensuring that data is retained even during power outages.
Installation and Operation
Preparation for Installation
- Before beginning the installation of the module, it is essential to ensure proper safety and system integrity. The first step in the process is to disconnect the power from the rack. This is a critical step to prevent any electrical hazards or potential damage to the system during installation. Once the power is disconnected, place the three-position control switch on the module into the stop position. This ensures that the CPU is not running while you perform the installation, which helps to avoid any inadvertent errors or malfunctions.
- Additionally, ensure that the necessary components for installation, such as the memory expansion board and CMOS battery, are ready for connection. The memory expansion board should be securely connected to the module, and the CMOS battery must be inserted into one of the available slots on the CPU. The CMOS battery is essential for maintaining system memory, ensuring that data is preserved during power outages or reboots.
Installation Process
- Once the preparation steps are completed, you can proceed with installing the module into the rack. Begin by inserting the CPU module into slot one of the rack. Make sure the module is securely seated in the slot and that all connectors are properly aligned. It’s crucial to handle the module with care to avoid damaging any pins or connectors during the installation process.
- After the CPU module is inserted, you can reconnect the power to the rack. Powering up the rack allows the system to begin the initialization process for the newly installed CPU. Be sure to check for any initial status indicators such as LEDs or diagnostic lights to confirm that the system is powered on correctly.
Operation
- Three-Position Control Switch: The device can be controlled directly via the three-position control switch on the module. This switch allows you to toggle between different operational states: Run, Stop, and Reset. The control switch provides manual operation for straightforward system control and troubleshooting without the need for external software.
- Computer Control with Software: Alternatively, the module can be operated and configured through a computer running the appropriate software. This method provides more advanced control and allows for programming, configuration, and real-time monitoring of the system. The software interface enables operators to configure the system according to their specific requirements, load programs, and make adjustments to parameters as necessary.
- Both methods of operation are designed to provide flexibility and ease of use, depending on the user’s preferences and the requirements of the automation system.
Troubleshooting
- LED Indicators:
- Top LED (OK LED): Indicates the overall status of the processor. If this LED is off or blinking, it suggests a problem with the processor.
- Middle LED (Run Enabled LED): Indicates if the processor is in run mode.
- Bottom LED (I/O Enabled LED): Indicates whether the I/O functions are active.
- Port Testing: Use Proficy Machine Edition to clear the controller and I/O fault tables, then download and run the hardware configuration and logic to test the processor’s port.
Additional Tests: Check the toggle switch located under the LEDs to ensure it functions correctly by flipping it on and off.
Long-Term Stability: If you suspect an issue with your processor, leave it in run mode overnight or over a weekend to verify stability.
Persistent Issues: If the processor fails to stay in run mode, it may require repair.
