Hi,  
I am communicating to the controller via the PC SDK, writing a variable. When I have no flexpendant connected, I put the robot into Auto, but I can’t write a variable and I get an exception stating something like “not in proper mode, must be in auto, manual or …”. It seems as if the auto mode is not acknowledged, but I can’t acknowledge anything when the flexpendant isn’t connected. What am I doing wrong?

Hi,

have you requested mastership from the Controller before you are writing the variable ?

e.g.

using (Mastership.Request(aController.Rapid))

{

rd.Value = aTool;

}

Yes, we were doing that. It appears that, when removing the flexpendant, you must first put it into auto (and acknowledge it). Either that or power on the system while the key switch is in auto. The issue has been resolved. Thanks.
