Functional Description

IS215VCMIH1CB is a Bus Master Controller Board developed by GE. It is a part of Mark VI control system. The VCMI serves as a pivotal communication interface within the control system, facilitating seamless interaction between the controller and the I/O boards. Moreover, it acts as the conduit for communication within the system control network, commonly referred to as IONet. In its role as the VME bus master, the VCMI assumes command in both the control and I/O racks, orchestrating data flow and coordination among the interconnected components.

Features

  • One of the key responsibilities of the VCMI is the management of board identities within the rack, along with their corresponding terminal boards. This entails assigning and overseeing unique identifiers for each board, ensuring efficient communication and interaction throughout the system. By overseeing these crucial aspects of communication and coordination, the VCMI plays a central role in maintaining the integrity and functionality of the control system.
  • In the context of a larger system featuring remote I/O racks, the architecture incorporates multiple IONets, each capable of accommodating several I/O racks. While the depiction presented illustrates only a single rack, it serves as a representative example of the broader system configuration. Notably, all I/O channels denoted as R, S, and T maintain uniformity in terms of the types of I/O boards installed and the array of points they support.
  • The design philosophy behind this setup prioritizes scalability and consistency across the I/O infrastructure. By standardizing the I/O channels with identical configurations and capabilities, the system ensures seamless interoperability and ease of management across multiple racks and IONets. This uniformity simplifies the deployment and maintenance processes, facilitating efficient operation and enhancing overall system reliability.
  • While the illustrated scenario showcases a single I/O rack within the larger system framework, it exemplifies the modular and scalable nature of the architecture, capable of accommodating additional racks and expanding I/O capacity as required. This approach offers flexibility and adaptability to evolving operational needs, making it well-suited for diverse industrial applications requiring robust and reliable I/O solutions.

Diagnostics

  • Monitoring Power Supply Buses: The system meticulously monitors internal power supply buses, including the 5 V, 12 V, 15 V, and 28 V buses. Any deviations from predefined voltage thresholds trigger alarms, enabling swift detection and resolution of potential issues.
  • Configurable Alarm Thresholds: Alarm thresholds for voltage deviations are configurable, typically set at 3.5 percent for most buses. However, the 28 V supplies have a threshold of 5.5 percent, ensuring appropriate sensitivity to voltage variations.
  • Power Distribution Module (PDM) Signals: Diagnostic signals from the PDM are also closely monitored. These signals encompass various parameters such as ground fault detection, over/under voltage monitoring on the P125 V bus, and digital inputs, providing a comprehensive view of the power distribution system's health.
  • External Monitoring Circuits: The PDM facilitates external monitoring circuits through differential ±5V dc analog inputs (P28A and PCOM), enhancing the system's diagnostic capabilities by integrating additional monitoring functionality.
