The setting for a
complete trace
is particular simple: By pressing the button "Set
All" (or automatic assumption of the slave list from the online statistics) you get the
correct configuration of the filter.

Trace View Filter
With a trace view filter not the number of captured telegrams but the representati-
on in the PC is limited. The representation is reduced to certain data packets, in
order to filter only data which are really interesting. This presentation can be chan-
ged at any time.
A mask under "
Options / Trace View Filter
" stands for disposal for the definition
of the filter conditions. also it is similarly build as the mask for the internal trigger
and the recording filter. Apply as in the mask for the internal trigger and the recor-
ding filter.

Trace without Notebook
The analyser can take up a trace even when a notebook is not attached constantly.
The notebook (or a PC) is only required for the determination of the settings and
for the (manual) start, as well as for al subsequent read out of the traces. This con-
figuration is interesting if a trace starts only due to a rarely arising trigger condition
or if a very long recording time is necessary effected by a recording filter.
This kind of storage and of the following analysis is supported in a user friendly
way: If the notebook is attached after storage to the analyser again, the analyser
software recognizes this situation. The software does not only read out the stored
trace automatically, but also the trigger conditions and filters, stored in the analy-
ser. So the user gets a consistent view afterwards.
5.7.8
Safety Data in the Trace
the analyser software can analyze the telegrams of safety-related slaves for code
violations. The software works in this analysis similarly to a safety monitor. Being
a passive participant the analyser cannot intervene.
The AS-i master sends search calls cyclically to all addresses,
including B-addresses (inclusion-phase). If a single slave is
selected, the calls to the corresponding B-addresses cannot be indi-
cated.
The field "Show Management Calls of B-Slaves at Single Address"
exists to prevent this. It shows exactly these calls.
The displayed result of a trace depends on the combination of the
recording filter and the view filter. Arbitrary combinations are possi-
ble in order to achieve the greatest flexibility for the analyser use.
This can lead to situations hardly interpretable. In a normal applica-
tion you should take care that only slaves are searched which are
actually in the net or should have to be found there. So unsatisfac-
tory representations can be avoided.
