As a relative newbie to Siemens I can not seem to find any documentation that explains the following. In an FB I have the following code (see image).
What i don't understand is how TEMP variable byte "H_Fehl_Stat"'s address is 6.0, yet in the ladder, bits L5.0, L5.1, L5.2 are being used to set data in this byte. Please can someone explain!? I would have thought you'd need to set bits L6.X.
