Hi Michal --
The variable in question appears to be BoardID. The entire message is "App: ReadValue (Board ID) done [ERROR code=0x80000116]" repeated over and over. At intervals, it changes up the variable to a bunch of others, but BoardID is the most common.
I don't see any way to set that in FREEMaster.
Possibly separate, or possibly not, I also get a "Script Error" dialog box every time I select the "Motor Idendif" tab. The box says "An error has occurred in the script on this page." Line 426, char 9 "Error:"CharArray" is undefined". Code: 0. It tries to supply a URL, but the path is too long, and it is truncated before telling me anything useful.Could this be related?
