Exactly when are the installation variables saved to disk?
Is it possible to force the installation variables to be saved, when the robot is in “Run Program”?
The installation variables are saved every ten minutes when running and during the controller shutdown process. I do not believe there is a way to force the installation variables to save more regularly, so if this is necessary I would recommend that instead of using the standard installation variables you use XMLRPC to pass your variables to a Python Daemon that then saves them to a text file on demand.
Thanks @ajp for the detailed answer.
