• Each port serves one channel in triple redundant systems (R, S, T), ensuring separate communication paths for maximum reliability.
• How does this board function as a VME bus master?
• It controls all VME bus communications, manages board identification, and coordinates data transfer between system components.
• What types of systems use this controller board?
• It serves simplex systems with local I/O and larger systems with distributed I/O racks across gas, steam, and wind turbine applications.
• Why are spare VCMI boards recommended?
• This critical component ensures system operation, making spares essential for minimizing downtime during maintenance or failures.
• What do the front panel LED indicators show?
• They display run status, failure conditions, system status, and provide visual feedback for reset operations and channel activity.
