• Self-supervision summary = INT--FAIL and INT--WARNING
• CPU-module status summary = INT--CPUFAIL and INT--CPUWARN
When an internal fault has occurred, extensive information can be retrieved about the fault from
the list of internal events. The list is available in the TERM-STS Terminal Status part of the CAP
tool. This time-tagged list has information with the date and time of the last 40 internal events.
The internal events in the list do not only refer to faults in the terminal, but also to other activi-
