Functioning (IF%) and non-functioning (IN%) rates are calculated only for “not ignored” objects. For “ignored” objects, rates are not calculated and the filter is never used (see Ignоring objects Ignoring object). Zero values of non-functioning rates are not shown on the status bar. Rates (IF% and IN%) are not calculated if Alarms, Failures or Disconnected filter is enabled (see Number of alarms displayed). |
Functioning rate (IF%) is calculated according to the following formula:
(1-Nnf/Na)*100, where
- Nnf is the number of objects that do not function properly;
- Na is the total number of objects.
The non-functioning rate (IN%) for a particular reason is calculated according to the following formula:
(Nnfbr/Na)*100, where
- Nnfbr is the number of objects that do not function properly for this particular reason;
- Na is the total number of objects.
