Block Parameter Set of block 1
Example:
Add a constant value and an external additional reference to the speed reference:
1. Set 84.04 = 2 (selection of ADD function)
2. Set 84.05 = xx.xx (selection of the speed reference for Input 1)
3. Set 84.06 = xx.xx (selection of an external ref for Input 2)
4. Set 84.07 = 1500 (constant value for Input 3)
5. Set 84.08 = 4000h (because Input 3 = constant
⇒
Bit 14=1
⇒
4000h)
6. Set 86.01 = xx.xx (write processed value to destination parameter for further processing)
7. 84.09: contains the processed value

To use an
input as a
constantvalue,
the bit
belonging to
the inputmust
be set high.
This function offers the opportunity to isolate a
certain bit out of a packed Booleanword. It is used to
connect the Boolean inputs of a function
block to a
certain bit of a packed Booleanword. With:
Bit 0 == 0000 == 0h
Bit 1 == 0001 == 1h
…
Bit 15 == 1111 == Fh
