Functional Description

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.

Features

• Communication Interface: 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 maintaines connections with other networked devices, such as additional controllers, monitoring systems, or external interfaces.
• VME Bus Master: 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.
• Board and Terminal Board Management: Responsible for assigning and managing unique IDs for all the boards installed in the rack, including both the main controller boards and their associated terminal boards. This ID management ensures proper identification and communication between interconnected components.

Three simplex system configurations

The 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.
• Remote I/O Configuration: The VCMI extends its communication capabilities to remote I/O racks located at a distance from the main controller. By leveraging the IONet network, multiple remote I/O racks can be interconnected, allowing for seamless integration of distributed I/O devices. The VCMI serves as the gateway for transmitting control commands and receiving data from the remote I/O modules, enabling comprehensive system control and monitoring.
• Parallel IONet Configuration: To enhance data throughput and reduce latency for latency-sensitive applications, a second IONet port on the VCMI can be utilized. This parallel IONet configuration operates in tandem with the primary IONet connection, effectively doubling the network bandwidth and enabling faster data transfer rates. By leveraging parallel IONet connections, the system can handle high-volume data streams more efficiently, ensuring optimal performance in demanding applications.
