Functional Description

IS200BCNOH1A is a CANopen Master Gateway Module developed by GE. It is a part of Drive Control control system. It is a part of CANopen Master Gateway system. The CANopen network supports a specific set of devices for seamless integration and optimal performance.

Supported Devices

The module is designed to work with a specific set of CANopen-compatible devices. These include the Woodward™ GS6 and GS16 valves, which are typically used in turbine control systems for fuel and steam regulation. It also supports Woodward Digital Valve Positioners (DVP), enabling precise control over valve positioning. Additionally, the module integrates with GE Sensing DPS 8000 pressure transducers, which provide high-resolution pressure measurements vital for system feedback and closed-loop control.

Device Compatibility Constraints

One of the critical operational restrictions is that it does not support mixing different device types on the same CANopen network. This design decision ensures compatibility and communication reliability. Mixing devices with varying protocol interpretations, data formats, or update rates could lead to timing issues, communication errors, or even device failure. Enforcing uniform device types maintains signal integrity and simplifies configuration and diagnostics within the system.

Communication Capabilities

It operates via the COM-C communication module, which functions as the CANopen master node in the network. It supports a maximum baud rate of 500 kbps, which allows for fast and reliable communication between the master and connected field devices. This rate is suitable for real-time applications that require synchronized device operation and quick data retrieval, such as turbine actuation and high-speed process control.

Redundancy and Network Configurations

The module supports two main network configurations depending on the redundancy requirements of the application. In standard applications, a single I/O pack with a single Ethernet connection is sufficient, providing basic operational functionality. For enhanced fault tolerance, the system can be configured with a single I/O pack equipped with dual Ethernet connections, allowing for network redundancy. This setup ensures continuous communication even in the event of a primary network path failure, which is essential for mission-critical systems where uptime is a priority.

CANopen Gateway Hardware Features

The CANopen Gateway Hardware in the PCNO system utilizes the COM-C module, which is intricately designed to facilitate communication between various components within the network. Here's a detailed expansion on the hardware and its functionalities:

• COM-C Module Overview: The COM-C module is constructed around a CANopen core, which is derived from the Hilscher GmbH family of communication network interface modules. This core forms the foundation for efficient and reliable communication within the PCNO system.
• Firmware Management: The firmware of the COM-C module is stored in flash memory and is an integral part of the PCNO firmware package. During the startup of the I/O pack, the firmware is only downloaded to the COM-C flash if deemed necessary. This occurs, for instance, when there's an updated version of the COM-C firmware released alongside the PCNO firmware.
• CANopen Configuration File: In addition to firmware, the COM-C module requires a CANopen configuration file. This file is loaded from the ToolboxST application and specifies crucial parameters for the PCNO master, as well as other standard I/O pack configurations. Any changes made to the CANopen configuration file necessitate a reboot of the PCNO system for the changes to take effect.
• Flash Memory Management: Both the COM-C firmware file and the CANopen configuration file are stored in the flash memory of the COM-C module. However, these files are only downloaded from the PCNO flash to the COM-C flash if there are updates or changes required.
