6. Function blocks
6.1 Manufacturer function blocks
Note
OF=1, if the actual value QV is greater
than or equal to the upper threshold
value;
FB=1, if the actual value QV is less than
or equal to the lower threshold value;
If the value range is exceeded, the switch
contact switches to status 1 for one cycle
per rising edge detected. The function
block retains the value of the last valid
operation before the contact CY is set.
Integer value range:
-2,147,483,648 to +2,147,483,647
