7.6 Internal variables (oscilloscope signals)
The system variables of the regenerative power supply module's internal control listed in
the following table can be recorded with the oscilloscope for diagnostics and
documentation purposes.
 All further variables in the selection dialog of the oscilloscope are intended for closed-
loop controlled operation (in preparation).

Note!
The system variables of the internal control have a cycle offset of 2 ... 3 ms with
respect to all other variable values!
