To get more detailed information about the events, it is possible to expand the log entries
by clicking the “Expand all entries” link. Single log entries can be expanded by clicking the
individual plus symbol.
Block Repeated Faults
If a Status Log is received repeatedly, i.e. a Status Log with the same content and from the
same Unite Address, it can be blocked for a set period of time. Repeated Status Logs can
occur in the system for example if a Unite module sends Activity Logs to an UPAC that has
no licence to handle Activity Logs. Persistent Status Logs and reset of persistent faults will
never be blocked.
The UPAC will discard all blocked Status Logs that are received during the set time, i.e. if
the timeout is set to 10 minutes and the Status Log is received once every minute, every
tenth Status Log will be stored in the UPAC. No actions will be executed for the discarded
Status Logs.
The UPAC keeps track of up to 100 different Status Logs and the timeout is set individually
for each one of them.
The timeout is set on the “Administer Fault Log” page, see
below.
