Good Morning,

I am trying to build a station with two conveyors with robots that will load and offload on Robotstudio 5.06. I am doing this from stratch and desperately need all the help I can get.

Regards,

Unathi Kanda

Hi  
Grip and release(event table) isn’t supported in 5.06. You need to have 5.07 to do that.

Hi,

I have now finally installed Robotstudio 5.07 and on top of my conveyor tracking confusion, i cannot synchronize to vc. An unknown error is generated when I try.

I appreciate your help

Hi Unathi,

Do you have this problem with all your controllers, or only with one specific controller?

If it’s one specific controller you have problem with, perform a cold start of that controller and try again.

Hi Anders,

Everything else seems fine. I’ve created paths and instructions and am trying to simulate the program. I need to synchronize to the virtual controller in order to setup my simulation but the unkown error is generated everytime I try.

See error message below

# RobotStudio .NET exception dump

Base exception:

Thank you for your help.
