Overview
AS-Interface analyzer
The AS-Interface analyzer is used to test AS-Interface networks.
Installation errors, e. g. loose contacts or EMC interference
under extreme loads, can be revealed by this device.
Thanks to the easy-to-use software the user can assess the
quality of complete networks even if he lacks detailed specialist
knowledge of AS-Interface. In addition it is an easy matter with
the AS-Interface analyzer to create test logs from the records
produced, thus providing documentation for startups and
service assignments.
For advanced AS-Interface users there are trigger functions for
detailed diagnostics.
Connection
Connection of AS-Interface analyzer to PC and AS-Interface network
The AS-Interface analyzer follows the communication on the
AS-Interface network as a passive station. The unit is supplied
simultaneously from the AS-Interface cable.
This analyzer interprets the physical signals on the AS-Interface
network and records the communication.
The data thus obtained are transferred through an RS 232
interface to a PC such as a notebook, for evaluation with the
supplied diagnostics software.

Application
Online statistics
Online statistics, overview
Online statistics, details, e.g. here a fault on slave 5
This mode provides a quick overview of the existing AS-Interface
system. The error rates are displayed per slave in a traffic-light
function (green, yellow, red).
The bus configuration and the currently transmitted data of the
slaves are shown in a well arranged presentation.
With the expanded statistics function, it is possible to determine
the error rates as the number of transmitted or faulty bus mes-
sage frames.
The bundle error overview shows in steps how many multiple
repetitions of message frames occurred in order to enable
a selective and look-ahead assessment of the transmission
quality.
