Hello All,
I am not new to Step 7 programming but I am also by no means totally conversant in all the methods available to "create" the desired software for the clients purpose.
I have recently moved across to a new plant where the suppliers have used FBD as the default programming language and there is a liberal use of local TEMP variables between networks. (See #Tmp_Bool in attached screen capture.)
I don't understand what the purpose of the re-use of the #Tmp_Bool variable is in this situation? Why not just use a different variable each time, so that the normal plant tech like myself can see where the data is going?
How would a person follow the logic if each network output end in #tmp_bool?
Any help will be greatly appreciated.
Thanks,
Shaun Nel.
