numbers and the single parameters are displayed as hexadecimal values.
If you have chosen Hexadecimal format, the hexadecimal values of the

Time of Day including Time Difference CPU/Local
If the check box is not active, the entries in the diagnostic buffer are stamped with
the time of day on the module, for example, the CPU. You use this setting if this
time is the same as the time at the location of the diagnostic buffer reader (the
same time zone).
If the check box is active, the correction value set for the time-of-day display is
applied. You use this setting if the location of the diagnostic buffer reader is in a
different time zone than the module. The check box can only be activated for
modules which support time-of-day status.
If you change the settings, the time entries in the diagnostic buffer are updated
immediately.
