Functional Description

IS215VCMIH1CA is a Bus Master Controller Board developed by GE. It is a part of Mark VI control system. VCMI (VME Communication Interface) serves as a communication between the controller and the I/O boards within the control system. Additionally, it acts as the communication interface to the system control network, referred to as IONet. The VCMI plays multiple key roles within the control and I/O racks.

Features

• Communication Interface: It enables bidirectional communication between the controller and the I/O boards, ensuring seamless data exchange and coordination. Facilitates communication over the IONet, allowing connectivity to the broader control network and other interconnected devices.
• VME Bus Master: Within the control and I/O racks, the VCMI assumes the role of the VME bus master. It manages the VME bus communication protocol, coordinating data transfers and addressing schemes among the connected devices.
• ID Management: The VCMI is responsible for managing the identification (IDs) of all the boards within the rack and their associated terminal boards. It assigns and controls unique IDs for each board, ensuring proper recognition and communication within the system.

Diagnostics

• The diagnostic system of the control system encompasses comprehensive monitoring and alarming functionalities, ensuring the integrity and reliability of critical power supply buses and diagnostic signals.
• Power Supply Monitoring:
  • The internal 5 V, 12 V, 15 V, and 28 V power supply buses undergo continuous monitoring.
  • Alarm settings are configurable, typically set at 3.5 percent for most voltages, while the 28 V supplies have a threshold set at 5.5 percent.
  • This monitoring mechanism allows for early detection of deviations from nominal voltage levels, enabling preemptive actions to maintain system stability.
• Diagnostic Signals from Power Distribution Module (PDM):
  
  • Diagnostic signals from the power distribution module (PDM) are monitored through the J301 connection.
• Monitored signals include:
  
  • Ground fault detection and over/under voltage on the P125 V bus, providing insights into potential electrical abnormalities.
  • Two differential 5V dc analog inputs, designated as P28A and PCOM, utilized for external monitor circuits, enhancing diagnostic capabilities.
  • Digital inputs, offering additional diagnostic information to ensure comprehensive monitoring of system health.
