Functional Description
IS200VCMIH2BCC is a bus master controller board developed by GE. It is a part of Mark VI control system. The VME Bus Master Controller (VCMI) board serves as the linchpin of communication within the system architecture, facilitating seamless interaction between the controller, I/O boards, and the broader system control network known as IONet. As the central hub of connectivity, VCMI orchestrates data exchange and synchronization, ensuring optimal functionality across the control and I/O racks.
Features
- Communication Interface: At its core, VCMI acts as the primary communication interface bridging the controller and the array of I/O boards distributed throughout the system. Through its robust architecture and versatile design, VCMI establishes and maintains communication channels, enabling real-time data exchange and command execution with unparalleled efficiency.
- Integration with IONet: Beyond its role in intra-rack communication, it extends its reach to the broader system control network, IONet. Serving as a vital link between the local rack environment and the overarching control infrastructure, it enables seamless integration and interoperability, empowering the system to operate cohesively and responsively across diverse network topologies.
- VME Bus Master Functionality: As the designated VME bus master within the control and I/O racks, module assumes responsibility for managing the intricate network of interconnected boards. This entails coordinating bus access, addressing, and data transfer protocols, optimizing resource utilization and minimizing latency to ensure swift and efficient operation of the entire system.
- Board and Terminal Management: In addition to its communication duties, it takes on the crucial task of managing the unique identifiers (IDs) assigned to all boards within the rack, along with their associated terminal boards. This meticulous oversight ensures proper identification and configuration of each component, facilitating seamless integration and troubleshooting as needed.
Communication Capabilities
- IONet Connectivity: At the forefront of the communication arsenal are three IONet 10Base2 Ethernet ports, equipped with BNC connectors. These ports provide high-speed connectivity, boasting transmission rates of up to 10 Mbits/sec. By leveraging the robust Ethernet protocol, VCMI enables rapid data transfer, ensuring real-time communication between the system components and external networks.
- VME Bus Block Transfers: In addition to Ethernet connectivity, VCMI harnesses the power of VME bus block transfers to facilitate efficient data exchange within the system. By leveraging the VME bus architecture, the board optimizes data throughput, enabling seamless communication between the controller, I/O boards, and other interconnected devices. This high-speed data transfer capability enhances system responsiveness and performance, facilitating rapid decision-making and control.
- RS-232C Serial Port: Complementing its Ethernet and VME bus interfaces, VCMI features an RS-232C serial port, equipped with a D-style plug connector. Operating at a fixed baud rate of 9600, this serial port provides a reliable and standardized communication channel for interfacing with external devices. Whether for configuration, diagnostics, or data exchange, the RS-232C serial port enhances the versatility and interoperability of VCMI within diverse industrial environments.
Memory Features
- Dual-Port Memory: At the core memory architecture lies a dual-port memory module, boasting a capacity of 32 KB in a 32-bit transfer configuration. This dual-port memory facilitates concurrent access from multiple sources, enabling parallel data transfers and enhancing system throughput. With its robust design and high-speed operation, the dual-port memory module serves as a cornerstone of data communication within the system.
- Static Random Access Memory (SRAM): Supplementing the dual-port memory, it incorporates a 256k x 32 SRAM module. This SRAM module offers fast and reliable data storage, ensuring rapid access to critical system parameters and configuration settings. With its high-speed operation and non-volatile nature, SRAM provides the necessary flexibility and responsiveness for real-time data processing and control.
- Flash Memory: Features flash memory modules tailored to specific configurations. It includes a 512k x 8 flash memory module, while the VCMIH_C variant boasts an expanded capacity of 4096K x 8. These flash memory modules serve as non-volatile storage solutions, capable of retaining data even in the absence of power. By offering ample storage capacity and reliable data retention, flash memory enables secure storage of firmware, configuration files, and critical system logs, ensuring seamless operation and quick recovery in the event of system failure.

Frequently Asked Questions
What is IS200VCMIH2BCC?
It is a bus master controller board developed by GE under the Mark VI series.
How are the internal power supply buses monitored and alarmed?
The internal +5 V, 12 V, 15 V, and 28 V power supply buses are meticulously monitored and alarmed to ensure system integrity. Alarm settings are typically configured at 3.5 percent for most supplies, except for the 28 V supplies, which are set at 5.5 percent. These settings allow for prompt detection of deviations from nominal voltages, enabling proactive intervention to prevent potential system disruptions.
What diagnostic signals are monitored from the power distribution module (PDM)?
The power distribution module (PDM), connected through J301, provides critical diagnostic signals for monitoring. These signals include ground fault and over/under voltage on the P125 V bus, two differential 5V dc analog inputs (P28A and PCOM) for external monitor circuits, as well as digital inputs. By monitoring these signals, the system can promptly detect anomalies and mitigate potential risks to ensure reliable operation.
Why are alarm settings different for the 28 V supplies compared to other voltages?
The alarm settings for the 28 V supplies are set at a slightly higher threshold of 5.5 percent compared to other voltages. This adjustment accounts for the inherent variability and tolerance levels associated with higher voltage supplies. By setting a slightly wider tolerance range, the system maintains a balance between sensitivity to deviations and minimizing false alarms, ensuring effective monitoring without unnecessary disruptions.
