This may cross over with applications, but maybe not. If this is the wrong category I’ll repost it.
Anyway, I’m working on an application and I’d like to gather as much information about the module hardware currently connected to the Opto as possible. For analog cards I can retrieve the type/model of the module, whereas for digital it just says “Dig/None”. So I can’t get the model or even know if there is something connected in that slot. I saw an older post that seems to confirm that you just have to know what is connected, but it was posted over 10 years ago so I guess I’m just wondering if that is still the case and if I understood everything I’ve read about it so far.
If that is the case is there any way I can perform a test to at least see if a module is there like a ping or something?
