Description
The block provides a teach-in function for position values.
When
Execute has a rising edge, the position on PosIn is written to an element of
the array parameter on P64Array and saved non-volatilely on Paramodul.
The element of the array parameter is selected with the input Select . The block
checks the validity of the selection by comparing the value on Select with the
number of array elements specified on the input Elements .
Remember that the designation of the elements begins with 0. This means that
when there are five elements, for example, values 0 to 4 can be specified on
Select .
NOTE
If you use the block, remember that the number of storage cycles on Paramodul is
limited.
