Siemens S7/TIA v18: What does "Object Number" mean?...

[Mas01]

The picture attached relates to the properties for the F9 key.

Does anyone know what 'object number' refers to?

What does 'object number' mean?

I bet it's something really useful that I wish I'd known about a lot earlier...

Thanks

Have you tried pressing F1 while on that entry in the HMI design GUI?

I can only guess that it is the "Object Number" of the widget on the target screen that gets keyboard focus when that target screen is activated, so the user does not have to take an extra step to be able to e.g. start typing to enter a value into a text box widget.


This is only a guess; if there are object numbers assigned to each widget (button, shape, text box, etc.) on a screen and those are available to, then the likelihood of it being a good guess goes up.

Cool @drbitboy!

I've pressed F1 before for general help, but didn't realise it was also selection-specific!

I shall read further - that's a neat feature!
Cheers

Yeah, it's the tab sequence number of the widget (object) that gets focus after the screen change.
