GE IS215VCMIH2BE Mark V IS200VCMIH2BEE VME Bus Master Controller Board

VME Bus ManagementAs a VME bus master device, it is responsible for address decoding, bus arbitration and data transmission control, coordinating the bus access timing of all boards within the chassis to avoid data conflicts. It also features error detection and fault isolation capabilities to ensure the stability and integrity of bus communication.

Communication Interface BridgingOn the one hand, it performs high-speed data interaction with controllers and I/O boards (e.g., analog input/output boards, digital I/O boards, etc.) via backplane connectors. On the other hand, it connects to the system control network through 3 IONet interfaces, enabling cross-network communication between controllers and distributed I/O chassis. Additionally, it provides 1 RS-232C serial port for diagnostic and configuration operations.

Chassis ID ManagementIt assigns unique identifiers to all boards and their associated terminal boards within the chassis, enabling precise addressing and management of the boards. It supports connection of multiple I/O chassis to the same IONet network, with each chassis requiring a dedicated VCMI board to meet system expansion requirements.

Status Monitoring and DiagnosticsIt is equipped with Run, Fail, Status indicator lights, as well as communication status lights including TX (Transmit), RX (Receive) and CD (Carrier Detect). There are also 4 binary-coded indicator lights (1, 2, 4, 8) for fault code display, which, together with a manual reset button, facilitate quick fault location and troubleshooting. It receives analog and digital feedback on power supply status via the J301 backplane connector to realize power supply monitoring and abnormal alarm functions.

System Integration and AdaptationIt is compatible with the simplex configuration of the Mark V system and supports local and remote I/O deployment. It enables transmission and conditioning of various industrial signals such as LVDT input, servo valve output, thermocouple input and 4-20mA signals, meeting the complex signal processing requirements of gas turbine control systems.
