KR C2 More then one seam in one programm

Hi all.

I have a problem with executing more then one welding seams in one programm on my Kuka KR C2.

It weld one seam just fine, but then it stops. It continuing it path right to the start of the next seam (ARC ON instruction) and then stop.

At first there was "Process is active" notification, which is one of the signals from I/O mapping from welding machine and it obvious why it would not start. This signal is active for a few seconds and then turning off (so, basicly, welding machine saying that weilding of that seam is completed). And in ARCTech there is an timing option for "Seam end" condition. But it aperantly isn't working.

I tried unlist "Process is active" signal from I/O mapping, but second seam still don't want to start. And it lists no errors.

If i try to make this with two separate programs (each one with one seam) and call them from the third one - it's works fine. The problem is in more seams in one programm. Honestly, i have no idea, what's wrong with it.

So... What should I try to check first? There is no usefull info about this in ArcTech manual.

More info about setup:

Kuka KR C2 v5.5.16 / KR 60 L30 HA

ArcTech Digital 3.2.4

Kemppi KemArc Pulse 450 connected via DeviceNet

For me it looks like messed up procedure for end of the seam in config.dat

Check again all the signals where you define the end of a seam in Arc.Tech section in config. dat

Never used Kempi, so cannot help with the IO numbers

Thank you, i'll check that out. But the strangest thing for me that it don't starting second seam even in "simulation" run.
