Dear Sir ,

Presently am working on S7 programming and have following query .

In Step 7 PLC how the local data is distributed over FBs and FCs those are called in respective OBs. Going further consider my case where I used standard FBs and called that in Multiple instance of another FB . Standard FB that we have used is having about 10 bytes Temp data , when I call that in another FB for multiple instance where that Temp data goes ? in other words which memory that block will use for Temp calculations ?

Thanks in advance
