Kuka KR 6-2 + Kemppi 450 Pulse

Who did connection kuka and kemppi with help devicenet, can u send me message. I have problem with connection. I use EK1100 and EL6752. I have checked a lot already, the project too (there are questions about the ArcPulseEN settings whether they affect the connection. I am using the default values . But still there is an error that station 3 (welding machine) is not activated. But I have 24V on EK1100. Tell me what you can do?
