AS-Interface Analyser
5.4
Logging of the Online Statistics
The results of the online statistics (overview, configuration, advanced statistics
and consecutive errors, as well as minimum and maximum value of the voltage)
can be printed out or stored as standardized protocol. The protocol can be supple-
mented manually in the form by a description of facility including the indication of
the type of the used components manually. This describes the facility completely.
The data from the analyser are protected (fig. 7).
Subject to reasonable modifications due to technical advances.

Functions of the Analyser
Four restrictions are to be considered with the work without a note-
book:
• Measured values remain stored only as long as the analyser is
supplied out of AS-Interface net. The notebook must be attached
to the analyser for further analysis.
• If the notebook is attached to the analyser first (for example to set-
up the analyser), but then removed, the data stored up to this point
is deleted (the filter adjustments remain however!).
• The indication "Measuring Time" is generated by the PC and not
by the analyser. Therefore, the "Measuring Time" can be indicated
only if the online statistics have been deleted at least one time via
the PC and have been started again in this way. Therefore, it con-
tinues to run also if the communication is temporarily interrupted by
the master or the user program but the voltage in the AS-Interface
net persists.
• The memory in the analyser is limited. In the continuous mode
without attached notebook data can be stored max. 14 days in the
statistic mode. The counter stops if it reached its maximum value.
With attached notebook this period is extended to approximately
1 year.
