Redundancy and Backup Capabilities

The IC697CGR935 is crucial for CPU redundancy applications, offering:

    Bumpless switching: Ensures seamless transitions between primary and backup controllers, keeping the system operational at all times.
    CPU synchronization: Maintains synchronized operation between the primary and secondary CPUs.
    Configurable backup data size: Provides flexibility in redundancy configuration to suit your system's needs.

Installation and Configuration

The IC697CGR935 installation and configuration process includes the following steps:

    Connect the battery: Ensure the battery is connected to one of the module's battery connectors to maintain memory retention.
    Toggle switch: Set the switch to the STOP position before installation.
    Memory protection: Turn off memory protection before programming.
    Install the module: Place the CGR935 in slot 1 of rack 0 (as shown in the installation diagram).
    Power up: Once installed, power on the system. The OK LED will blink during diagnostics and remain on once completed.

Communication Ports

The IC697CGR935 offers three communication ports:

    Port 1 (RS-232): Provides serial communication via an RJ-11 connector.
    Port 2 (RS-485): Optically isolated, suitable for differential communication.
    Port 3 (RS-485): Non-isolated port for additional communication needs.

Ethernet TCP/IP Connectivity

To program the CPU via Ethernet TCP/IP, an Ethernet Interface Module (e.g., IC697CMM741) is required. Once the IP address is configured, you can connect the CPU to the network for remote programming and control.

Conclusion and Recommendations

The IC697CGR935 is an ideal choice for mission-critical applications that require high availability and fault-tolerant systems. Its high-speed processing, seamless redundancy switching, and flexible communication options make it a key component in industrial automation systems.

For those looking for continuous operation and uninterrupted control, the IC697CGR935 offers bumpless transitions between primary and backup controllers, ensuring your system stays up and running under all conditions.
