7.2.10.4 Parameter output
variabel operand value unsigned
variabel operand value signed
Value of the parameter selected in "variable operand address" after applying the read standardization and
overlaying of the mask from do46.
This value is the comparison operand at do01 / do02 = "70: variable operand value [1]“ or "71: variable op-
erand value [2]“.
The value is displayed in do47 as "unsigned" and in do48 as "signed" value. The value is the same, only
the display is easier to read.
The evaluation alwaas occurs as INT32 comparison and is only possible with do06 flag level 2.
Generation of the linked function blocks
The maximum number of connected function blocks ("connected flags") is set in do16
number of connected flags.
In order to optimise the runtime, the number of "connected flags" can be reduced to the
ones that are really required.
number of connected flags
no linked function blocks are calculated
1 ... 4 linked function blocks are generated. Non-generated linked function blocks lead to
the value 0 for the respective flag CF1..CF4
A "connected flag" is defined with a subindex in the array do13
In do13, it is determined from which function
blocks linked function blocks (connected flags)
shall be generated.
Max. 4 linked function blocks (CF1..CF4) are pos-
sible
The type of linkage is set in do18
With do18 it is selected whether the flags shall be OR or AND linked
AND operation for connected flags
Flags selected for CF1 are OR linked
Flags selected for CF1 are AND linked
Flags selected for CF4 are OR linked
Flags selected for CF4 are AND linked
