I was just recently out to help an older Kuka.
Specifically it was a KR120r3200 /KRC4 running kss 8.2.20
None of the versions of work visual i could get my fingers on, was able to open the project.
I tried with 4.** , told me it was too new, and that it didnt want to speak to such an old robot
Then i tried with WorkVisual_V2.4.5_Build0091 and WorkVisual_V2.4.6_Build0098
These would open the project, but
Neither the project on the robot, nor the ones we had in our backup archive.
They all kept complaining about a dtm error.
I think i tracked it to the KUKA-DEV io item
I then, in desperation tried to recreate the project from scratch, only to find that
None of these old versions supported the KR120/R3200 Robot.
They would support other KR120's but the R3200 wasn't there yet.
Does anyone have any experience regarding what version of Workvisual would support 8.2.20 ?
