Function of Boolean Sequence Function Block
The function block creates the sequence depending on the operating mode.
AND Boolean Sequence
OR Boolean Sequence
XOR Boolean Sequence
NOT Boolean Sequence
IMPORTANT
If you sequence a negative value, e.g.: -10
dec
, the processor
unit will form the two's complement of the amount.
Example:
-10
dec
= 10000000000000000000000000001010
bin
Two's complement =
11111111111111111111111111110110
bin
=
FFFFFFF6
hex
Bit 32 is the signed bit and remains as 1.
