Functional Description

IC697CGR935-JB is a Single Slot CPU developed by GE. It is a part of Mark I and II control system, specifically designed for CPU redundancy applications. This module is part of the redundant control system, where it plays a crucial role in managing fluctuating point calculations necessary for ensuring uninterrupted operation of complex systems. 

Features and Control Methods

• The module supports two primary control methods: the GHS process and the GDB process. Both methods are implemented to enhance the flexibility and functionality of the control system.
• GHS Process (Global Hot Standby): This method uses multiple single bus networks with one redundant controller in each synchronized PLC. The redundancy ensures that if one controller fails, the other can take over without causing a system disruption.
• GDB Process (Global Distributed Bus): In this method, multiple I/O networks are employed with single or double buses in each synchronized PLC. This setup provides a distributed and robust network, allowing for seamless operations even if one bus or controller fails. Each control method is easily activated, making the system flexible and adaptable to varying operational needs. Both of these methods are designed to be intuitive and can be activated without difficulty, allowing users to quickly integrate them into their existing systems.

Memory and Program Handling

The module is equipped with its own memory board, which is responsible for handling data and program memory. This built-in memory allows the module to function efficiently and independently in a redundancy setup, ensuring that critical data is available at all times for system operations. The program memory is included within the module, reducing the need for external memory sources, thus simplifying the overall system architecture.

Remote Operation and Control

The module can be operated remotely, making it convenient for use in automated and large-scale industrial environments. Alternatively, it can also be controlled via the three-position RUN/STOP switch located on the module. This manual control option provides users with an easy way to toggle between different operational states.

The front of the module is equipped with LED indicators, which display the status of the CPU. These LEDs offer clear feedback, allowing operators to quickly assess the module's operational state and troubleshoot potential issues.

Installation and Setup Procedure

The installation of the module should be carried out following the instructions in the Programmable Controller Installation and Hot Standby CPU Redundancy Manual. This manual contains detailed guidance on proper module installation and configuration, ensuring optimal performance and system reliability. Here’s a step-by-step outline for installation:

• Battery Connection: First, ensure the battery is properly connected to one of the module's battery connectors. This is necessary to maintain the module's memory during power outages or resets.
• Key Switch Position: The key switch should be set to MEMORY PROTECT OFF. This allows the CPU to access memory for both reading and writing.
• Power Conditions: Ensure that there is no rack power when installing the module to prevent any electrical hazards or damage during the setup process.
• Slot Placement: Install the IC697CGR935 module into slot 1 of rack 0. Once installed, turn on the power to the rack.
• LED Behavior: After powering up the system, the top LED will start blinking, indicating that the module is powered on. Once the module completes its self-diagnostics, the top left LED will remain lit, while the second and third LEDs will turn off. The MEMORY PROTECT LED (the fourth LED) will also be off because the key switch is in the "off" position.

Programming and Operation

Once the module has passed its diagnostic checks and the LEDs indicate normal operation, the system is ready for programming. The CPU can be programmed regardless of the position of the key switch, providing flexibility in program development and modification. After programming the CPU, the toggle switch can be set to the appropriate operational mode for the system's intended use. The system can be easily switched between run and stop modes, offering versatility and control in various operational scenarios.
