Functional Description
IS200VCMIH1A is a Bus Master Controller developed by GE. It is part of the Mark VI series. As an integral component of the VME backplane, it facilitates the seamless exchange of internal information among various system components. This includes I/O cards housed within its own rack system, as well as those installed on interface modules, protection modules, control modules, and the main processor card. By acting as a communication bridge, it enables the efficient transfer of data essential for system operation and monitoring. This data transmission encompasses a wide range of signals and parameters, including sensor readings, control commands, status updates, and diagnostic information.
Communication Interface
- Controller-to-I/O Board Communication: VCMI acts as the intermediary, enabling seamless communication between the controller and the I/O boards. This functionality is fundamental for data exchange, commands, and instructions between these components.
- System Control Network Interface (IONet): It serves as the gateway for communication with the IONet, the system's control network. This connection allows for broader networked interactions, data transfer, and system control across multiple components.
VME Bus Master and Management Functions
- VME Bus Master: As the VME bus master within the control and I/O racks, VCMI assumes a pivotal role in coordinating and controlling data traffic and access within the VME (Versa Module Eurocard) bus architecture.
- Board ID Management: VCMI takes charge of managing the identification (ID) of all boards situated within the rack, along with their corresponding terminal boards. This involves assigning, monitoring, and overseeing the unique IDs for these components, ensuring proper recognition and operation within the system architecture.
Overall System Integration
- System Synchronization: By managing board IDs and serving as a communication interface, VCMI plays a vital role in synchronizing the various elements within the system.
- This synchronization fosters efficient and coordinated interactions between different system components, enhancing overall system performance and functionality.
System Integrity and Control
- Control and Supervision: Acts as a control hub, overseeing communication, managing IDs, and ensuring system integrity. Its supervisory role contributes to the system's stability and operational reliability by maintaining proper connections and functionalities between boards.
- The multifaceted roles of the board encompassing communication facilitation, ID management, system synchronization, and control underscore its significance in enabling effective data exchange, networked operations, and system-wide integration within the control and I/O racks.
Board Type and Dimensions
- Board Size: The VCMI board follows the 6U high VME standard, measuring 6.0 inches in height.
- Width: It has a width of 0.787 inches, complying with standard VME board dimensions.
- Processor Type: The VCMI board integrates a Texas Instruments TMS320C32 32-bit digital signal processor. This processor is renowned for its high performance in handling signal processing tasks and computations.
Memory Configurations
- Dual-Port Memory: The board incorporates dual-port memory, featuring a 32 Kbytes capacity in a 32-bit transfer configuration. This dual-port memory architecture allows for concurrent access by multiple devices, facilitating efficient data transfer.
- SRAM (Static Random Access Memory): The VCMI board houses SRAM with a size of 64k x 32, providing high-speed and low-latency access to data critical for real-time processing and temporary storage of information.
- Flash Memory: It is equipped with flash memory having a capacity of 128k x 8. This non-volatile memory enables the retention of data even when the power is turned off and is commonly used for program storage and system firmware.
