IS215VCMIH2BC is a Bus Master Controller Board developed by GE. It is a part of Mark VI control system. VCMI serves as a communication link within the control system architecture, facilitating seamless interaction between the controller, I/O boards, and the system control network, referred to as IONet. Acting as both a communication interface and a VME bus master, the VCMI assumes central control over data exchange and management within the control and I/O racks.

IS215VCMIH2BC  Enables bidirectional communication between the controller and the various I/O boards distributed throughout the system. It serves as the conduit for transmitting control commands, receiving data, and facilitating real-time communication between different components.

System Control Network (IONet): As the communication interface to the system control network (IONet), establishes and maintains connections with other networked devices, such as additional controllers, monitoring systems, or external interfaces.

IS215VCMIH2BC Within the control and I/O racks, assumes the role of the VME bus master. This entails managing the VME bus protocol, controlling bus access, and coordinating data transfers between the controller, I/O boards, and other VME-compatible devices.

The IS215VCMIH2BC  VCMI (VME Control Module Interface) facilitates the implementation of three simplex system configurations, each utilizing both local and remote I/O capabilities. These configurations leverage the VCMI's versatility to establish robust communication channels between the controller and I/O modules distributed throughout the system.

Local I/O Configuration: In this setup, the VCMI communicates directly with locally connected I/O modules within the same rack. Data exchange occurs swiftly and efficiently, as the VCMI acts as the central hub for coordinating communication between the controller and the local I/O devices. This configuration is ideal for applications where real-time data processing and low latency are critical.
