Could anybody advise me how to configure a system s1500 - master and kuka krc4 - slave in the tia portal v15+? I mean that I don't understand should I use Tsend/Trecieve blocks to set I/O exchange between s1500 and kuka krc4? either not?
For example,when I needed to connect s300 plc as master to kuka krc4 and create i/o exchange, I had to create different FC blocks, OB80, OB81 -- OB86 (clearly don't know the purpose, these were empty, but the manual told me to use it). Moreover, PNIO_send and PNIO_recv were also used to control inputs of kuka by s300 and outputs of s300 by kuka . So what's he difference while making the same kind of connection by Tia Portal? I didn't manage to find useful manual on this theme.
Besides, I know about MxAutomation, but that's not what I want.
