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 indicators and switching outputs at D-sub connection
EXT (see section on X41) sort the display value into one of
three classes.
