Overview
The AS-Interface Analyzer is used to test AS-Interface networks.
Troubleshooting is made systematic, and permanent monitoring
is made easier.
Faults during installation, e.g. loose contacts or EMC problems
with extreme loads, can be detected by this analyzer.
The easily used software permits checking of the quality of com-
plete networks without having detailed technical knowledge of
the AS-Interface. The AS-Interface Analyzer additionally permits
documentation for commissioning and implemented services
through the simple generation of test reports for the recordings
made.
Detailed diagnostics is made possible for advanced
AS-Interface users by means of trigger functions.

Benefits
• Simple and convenient operation permits diagnostics of
AS-Interface networks without specialists.
• Fast troubleshooting is made possible by the intuitive display
in statistics mode.
• Test reports provide proof of the state and quality of the instal-
lation for servicing and approval.
• Reports facilitate remote diagnostics by the technical assis-
tance department.
• Advanced trigger functions permit exact analysis.
• Process data can be monitored online.

Function
Connection
As a passive station, the AS-Interface Analyzer listens to the
communication on the AS-Interface network. At the same time,
the analyzer is powered from the AS-Interface cable.
This bus monitor interprets the physical signals, and records the
communication.
The obtained data are transferred to a PC (usually a notebook)
via an RS232 interface, and evaluated there using the supplied
diagnostics software.
Online statistics
This mode provides a fast overview of the existing AS-Interface
system. The error rates per slave are displayed in a traffic signal
function (green, yellow, red).
The slave configuration and the currently transmitted data are
displayed in a clear manner.
The expanded statistics provides information on the numerical
data of the transmitted telegrams.
