Explanations on the function diagrams - Explanation of the symbols (part 2)
Pre-assigned binectors and connectors
Symbols for computational and closed-loop
control functions
Threshold value switch 1/0
Outputs at y a logical "1" if x < S.
Simple changeover switch
The switch position is shown according to
the factory setting of pxxxx (in this case
switch position 1).
Limiter
x is limited to the upper limit LU and the lower limit
LL and output at y.
The digital signals MLU and MLL have the value
"1", if the upper or lower limit is active.

Threshold value switch 1/0 with
hysteresis
Outputs at y a logical "1" if x < S.
If x >= S + H, then y returns to 0.
