Where can you call the "B Stack" in TIA Portal v12?

In Step 7 v5.5 you go online to the diagnostics and there you have the tab "Stacks" where you can find where the PLC went into stop. I don't seem to find this in TIA Portal. For example at this time, I made a programming error in the PLC. Somewhere there is a loop causing the PLC to exceed it's cycle time and go into stop. To find the error, I off course need to see what the PLC was doing at that time, which FB, FC, DB it was operating. Any help is welcome. PS: I know there is a button "Open in editor" with the online "Diagnostic buffer", but this button is not activated with the message "STOP caused by time error...". So at this time it's useless. And besides, I want to look into the stacks. They were there for a reason! Where are they?

Attachment). Regards, not_my_fault Attachment D:\Baustein_Stack.pdf (1267 Downloads)
