The GE Fanuc IC697CPU788 brings powerful processing and redundancy capabilities to the Series 90-70 platform. This CPU module specifically supports Triple Modular Redundancy (TMR) configurations, making it ideal for mission-critical applications. The module houses an 80386DX processor running at 16 megahertz, delivering fast and reliable logic execution. Moreover, the IC697CPU788 handles complex control tasks with a Boolean execution time of just 0.4 microseconds. You can deploy this module in emergency shutdown systems, fire and gas detection networks, and other safety-related control environments where uptime matters most.
The IC697CPU788 uses a robust 80386DX microprocessor clocked at 16 megahertz. This processor delivers excellent performance for both discrete and analog control applications. The module processes Boolean functions in only 0.4 microseconds, ensuring rapid response to input changes. Furthermore, the CPU supports up to 352 discrete inputs and outputs in simplex mode. It also handles 8000 analog inputs and 8000 analog outputs in simplex mode, providing substantial I/O capacity for large-scale systems. Such processing power makes the IC697CPU788 suitable for demanding industrial processes that require both speed and precision.
The IC697CPU788 distinguishes itself through its dedicated TMR design. This module works specifically in systems that require triple-modular redundancy for enhanced reliability and fault tolerance. However, the CPU will not function correctly until you include specific TMR program blocks in the loaded program. These blocks enable the TMR routines that synchronize multiple CPUs and ensure voting logic operates properly. Therefore, you must carefully prepare your program with these essential blocks before deploying the IC697CPU788 in any TMR application. This design ensures system integrity from the very first power cycle.
The IC697CPU788 provides flexible memory options through an expansion memory board. You can attach this board to gain up to 512 kilobytes of CMOS RAM. A lithium battery backs up this RAM, preserving program and data memory during power outages. The battery offers a shelf life of 10 years at 20 degrees Celsius and maintains memory retention for 6 months under normal conditions. This robust backup system protects your critical control logic and configuration data from unexpected power interruptions. Additionally, the module draws 1.6 Amps at 5 Volts DC, which includes the power consumption of the expansion memory board.
You can configure the IC697CPU788 using either Windows-based or DOS-based programming software. This flexibility accommodates different user preferences and legacy system requirements. The module features a 3-position RUN/STOP switch on its front panel. This switch provides three distinct operational modes: RUN, STOP, and PROTECTED. When you set the switch to PROTECTED mode, changes to the CPU configuration require a programmer connected to the parallel port. This security feature prevents accidental modifications during live operations. Additionally, you can control the module remotely through software commands, giving operators convenient access from a central control room.
The IC697CPU788 excels in safety-critical and high-availability applications. Common use cases include emergency shutdown (ESD) systems, fire detection and gas monitoring networks, and turbine control systems. Its TMR capability ensures that a single hardware failure will not compromise system operation. Furthermore, the module integrates seamlessly with other Series 90-70 components, including I/O modules, communication processors, and power supplies. You can build comprehensive control solutions around this CPU, leveraging its processing power and redundancy features to meet stringent safety standards.
The IC697CPU788 operates reliably within a temperature range of 0 to 60 degrees Celsius. This thermal tolerance suits most industrial environments, from climate-controlled control rooms to warmer factory floors. Additionally, the module features four status LEDs on its front panel. These indicators provide real-time system information, including power status, run/halt condition, and fault indications. Operators can quickly assess system health through these visual cues, reducing troubleshooting time and improving overall system availability.
Installing the IC697CPU788 follows a straightforward procedure. First, ensure the PLC chassis is powered off and disconnected from mains supply. Next, select an appropriate slot in the Series 90-70 rack, preferably one that provides adequate airflow for cooling. Slide the module into the slot along the guide rails until it seats firmly against the backplane connector. Then, secure the module using the retaining screws on the top and bottom. After installation, connect your programming device to the parallel port for initial configuration. Load your TMR-enabled program, ensuring you include the necessary TMR program blocks. Finally, set the RUN/STOP switch to the desired position and power on the system.

1. What is Triple Modular Redundancy and why does the IC697CPU788 need it?
Triple Modular Redundancy means the system uses three identical CPUs running in parallel, with a voting mechanism to detect and isolate faults. The IC697CPU788 specifically supports this architecture. Without the required TMR program blocks in your loaded program, the CPU will not function because it expects synchronization with other CPUs in the TMR configuration.
2. What memory capacity does the IC697CPU788 offer?
The base module works with an expansion memory board that provides up to 512 kilobytes of CMOS RAM. This battery-backed memory stores your control program and process data. The lithium battery maintains this memory for approximately 6 months during power loss.
3. How fast is the IC697CPU788 processor?
The module uses an 80386DX microprocessor clocked at 16 megahertz. It processes Boolean functions in just 0.4 microseconds. This speed makes the IC697CPU788 suitable for applications requiring fast logic scanning and quick response to input changes.
4. Can I use the IC697CPU788 in a simplex (non-redundant) system?
While this module primarily targets TMR systems, you can use it in simplex configurations as well. However, you still need to include the TMR program blocks for the module to operate. For non-redundant applications, consider other CPUs in the Series 90-70 family that do not require TMR-specific programming.
5. How do I protect the IC697CPU788 configuration from unauthorized changes?
You can set the 3-position RUN/STOP switch to the PROTECTED position. In this mode, only a programmer connected to the parallel port can modify the CPU configuration. This feature prevents accidental or unauthorized changes during normal operations.
