screen.
The application considers some historic events “special” and keeps track of how many
times they’ve occurred, as well as when they occurred first and when they occurred last. A
typical example of a special event would be some event that adversely impacts operation
of the UIM, such as a failure of Compact Flash.
Each special event counter can optionally be mapped in the DNP point map. See Instruc-
tion Sheet 1043-530, page 33. Whenever a special event thus mapped occurs, Data Logging
will notify the DNP communications layer of the UIM software about the occurrence. In
this way special event counter information can be made retrievable via SCADA.
Currently, the application can have up to 32 special events, which are contained on two
screens, linked with Page Up/Page Down buttons. Here are the pieces of data comprising
a Special Event Counter record, each residing in a separate column of the table on the
Special Event Counters screens:
Event Description
Describes briefly what the special event is. The list of all special events is further down. Note
that IL needs to be connected to the control for this column to contain any descriptions
Total Cnt
How many times the event has occurred since the application was downloaded first
Current Cnt
How many times the event has occurred since the special events were reset last time
(either using the “Clear Special Event Counters” feature on the Logging Setup screen, or
the identical feature in the lower right corner of this screen)
