AS-Interface Analyser

Functions of the Analyser
5.1
Overview
The Analyser is a "listener" in the AS-Interface network. It controls the message
traffic and evaluates it without intervening. The results are stored in the analyser,
then transmitted to a PC or notebook where it can be analysed and displayed.
The analyser listens and evaluates all signals (including incorrect signals) on the
AS-Interface line. So he can "hear" more than the most masters and especially
then any superior control.
This is used for logging the net status, for error analysis, and for the optimization
of the network and application.

Functions of the Analyser
Contrary to master and slave the analyser does not send telegrams.
it does not have permanent memory for the determined data and is
exclusively dependent on that what happens in the net.
It has got neither an address nor it keeps the configuration after
switching off. It is completely independent of data which are stored
in the master or an application program. The user has to consider
this evaluating the results.
