Good morning colegues. I need to know how can I write in a buffer adressing with a pointer var inside FB. If I write a global var in the code I haven't any problem but if I write over the local var the PLC down to Stop or no write in the memory register.
I have designed a program test for the simu.
If somebody could help me I can send it
Thank

Re: Indirect addresing within FB
in S7-300 / -400, local data when a bloc is open have random rumber (in fact it have previous bloc value)
if you don't recalculate the value eatch time, you need to store somewhere.
