Hi,
I'm super new to the whole Kuka system as of right now, but i'm getting the hang of it.
But the biggest challenge has been understanding how the I/O system works on the Kuka systems, since I have only worked with ABB plc's, so whole thing confuses me.
Right now I have a KR C5 Micro. So, I'm just trying to connect a simple connection for a pneumatic valve that uses just a + and - wires on 24v, basically an on/off switch. To my understanding I have to connect one of wires to the output of XG12 to give out the signal to the pneumatic valve and the other to XD12? And map them in WoV? From reading the manuals for it, is it correct the XD12 needs external power source to actually power itself and XG12?
Every information regarding how the whole I/O system works on Kuka system is welcome, because i'm still learning.
