Hi,

I use TIA Portal v15 Sp1 Upd4, Graph version 6.0

Does anyone know what is a function of a button “Step” (yellow frame on screen), and how make it working.

Another question, in manual there is fourth button named “Last step” (red frame on screen), but it is not available in TIA Portal, why?

And the last question, in PLC code viewer there are to buttons: previous network and next network (green frame on screen).

Do these buttons work also when in PLC code viewer I display Graph code, if yes do they allow to activate next or previous step or they are only used to navigate through steps?
