System diagnostics
The following methods are used for fault detection:
• Built-In System Test (BIST) that performs a comprehensive system test at power-on.
• Built-In Test Equipment (BITE) that continually checks for internal system faults
when the system is running.
• Additional self-checking facilities for system components such as I/O units, etc.
• Supervision of the controller computer fan and temperature.
• Comparison of data with preset maximum and minimum limits.
• Consistency checking of input measurements.
• Supervision of serial lines.
Any faults are reported.
Operational checks
The following checks are continuously carried out during system operation:
• Detection of possible degraded performance of the system.
• Logical checking of information.
• Comparison of data with preset maximum and minimum limits.
