Adding Bool & INT

[maico]

Hi All,
In siemens S7 is it possible to add the value of a Bool to an interger ie if I am adding 15 intergers together but have a further 2 Bool parameters to add is it possible to add them to the total sum?
Thx

No experience with siemens, but if you convert bool(s) to INT, yes you can add them.

Well a BOOL will either be equal to '1' or '0' so it would be easy enough to just have some Ladder logic to say...
If 'myBOOL' then ADD 1 to 'total' (where 'total' is the sum of your other INTs)

Or something like this in STL...

A  myBOOL
JNB  M001
L  myTotal
L 1
+I
T myTotal

M001: NOP 0

You would obviously have to make sure it didn't add every scan but something along those lines would work.

with couple move blocks or selection block you can make temperary variable which has value of zero or one, then add all ints together.

Siemens STL don't type compare variables, so you can also count variables there.
