The GE IS215UCCAM03A is a cPCI (Compact Peripheral Component Interconnect) Mark VI Controller for the Mark VIe series of GE’s Speedtronic Gas Turbine Control Systems. It is a critical component that serves as the central processing unit (CPU) for the entire control system. The “QNX6” in the description indicates that it runs on the QNX 6 Real-Time Operating System.
Key Features and Functionality
The IS215UCCAM03A is the “brain” of the Mark VIe system. Its main functions include:
- Control and Processing: The controller executes all the primary control algorithms for the turbine, including fuel scheduling, speed control, load regulation, and synchronization.
- Real-Time Operation: The use of the QNX 6 Real-Time Operating System ensures deterministic and high-speed performance, which is essential for the precise and rapid control required by gas turbines.
- cPCI Architecture: The controller is based on the cPCI (CompactPCI) bus architecture. cPCI is a rugged, high-performance industrial bus that provides reliable communication between the controller and the various I/O packs and modules.
- Communication: The controller handles all communication within the system and with external systems, such as a plant’s Distributed Control System (DCS) or SCADA system.
- Redundancy: In a redundant Mark VIe system (such as TMR – Triple Modular Redundancy), multiple UCCAM controllers work in parallel with voting logic to provide exceptional fault tolerance and reliability.
