Hello
any experience with replacing S5 with S7-1500 and having H1 working on it?  I do have CP 1543-1 to be used together with S7-1500.
AG_SEND/RECEIVE blocks are not available in TIA13 for this PLC.
Do I need to use "Open User Communication"/TSEND_C and TRCV_C to handle somehow ISO communication? 

I would be grateful for any code example for TIA13.
