GE IS215VCMIH2BC Bus Master Controller Board for Mark VI Turbine

The GE IS215VCMIH2BC(IS200VCMIH2BCC) is a Bus Master Controller Board in the Mark VI turbine control system, functioning as a critical communication hub that links controllers, I/O boards, and the IONet system network. As a VME bus master, it manages data exchange within control and I/O racks, coordinating real-time communication for turbine operations.

It assigns unique IDs to all rack-mounted boards and terminal boards, ensuring proper component identification. Supporting three simplex configurations—local I/O, remote I/O, and parallel IONet—it adapts to diverse system setups. Integral to gas, steam, and wind turbine control, it ensures seamless coordination between system elements.

• Communication Hub: Enables bidirectional data flow between controllers, I/O boards, and IONet, transmitting commands and receiving real-time data.
• VME Bus Mastery: Manages VME bus protocol, controlling access and coordinating transfers between system components for efficient operation.
• ID Management: Assigns unique identifiers to boards and terminal boards, ensuring accurate component recognition and communication.
• Flexible Configurations: Supports local I/O (low-latency rack communication), remote I/O (distributed racks via IONet), and parallel IONet (dual ports for high throughput).
• Simplex Versatility: Adapts to simplex setups with local/remote I/O integration, ideal for both centralized and distributed turbine control architectures.
• IONet Integration: Acts as a gateway to the system control network, facilitating connections with external devices and enhancing system scalability.
