For starters, Timer logic should be fed to the IN pin, EN should be true all the time.
I could isolate it like that... but so far this has worked fine.

For FB's, if EN is not true, that block is not executed at all. For simple example. If you have SFB4 and there is some condition #power that is for both EN and IN, when timer is passed its time and Q is true, now false at said #power would result Q being true as code that controls Q is not executed at all.
In network 5 there is sfb4 call with instance datablock 79. That is why it shows up in properties and that is why it cannot be used as multi-instance.
There is lot to clear tough. It seems very complicated, it takes some time to get what is done and where and why.
It sure shows you are new to siemens.
Temp cannot be used the way you use it in some cases. It must always be written to before its read in same fb or fc.
SET and RESET do not always write to, neither does move if its conditional.
