This may seem like a basic question, but for some reason I have having real trouble deciphering the built in help content, as well as navigating the official Siemens forums.
I have a program I've inherited (v14 of TIA Portal). There is an FB and a corresponding Instance DB (it is only instantiated once, so far). When I open this one IDB, the "Retain" setting is set for several (but not all) parameters, however the entire column is greyed out and I am unable to set (or unset) this setting.
I'm can't for the life of me figure out how to change this. I need to add some parameters to the FB definition and want to ensure they are retained.
Thanks.
