13.14.1 ST-Editor in Online Mode
In online mode the Structured Text Editor (ST-Editor) provides views for monitoring
and for writing and forcing the variables and expressions on the controller. Debugging
functionality (breakpoints, stepping etc.) is available. See below.
Monitoring
If the inline monitoring is not explicitly de-activated in the Options dialog, small
monitoring windows will be displayed behind each variable showing the actual value
(Inline Monitoring).

displayed in column 'Value' and the inline monitoring fields in the implementation
part will show three question marks each.
