Sorting and Tolerance Checking
In the sorting and tolerance checking mode, the display unit
compares the displayed value with the programmed upper and
lower sorting limits. The sorting and tolerance checking mode is
enabled and disabled with operating parameter P17.
Entering sorting limits
Sorting limits are entered in operating parameters P18 and P19
(see “Operating Parameters”).
Sorting signals
The display indicators and switching outputs at D-sub connec-
tion EXT (X41, see applicable section) sort the display value into
one of three classes.
