The AS-Interface Analyser
3.1
General
In the following you will find a detailed description of the AS-Interface Analyser.
The AS-Interface Analyser can give detailed information about the functionality of
new or existing AS-Interface networks.
It completes a master's possibilities, and it is the more valuable the less informati-
on beyond the standard AS-Interface data is provided by the master and the more
hidden an error is.
The analyser registers the entire data traffic without intervening and only evaluates
it. So network errors or errors from individual slaves can be easily identified and
corrected by the user. Configuration and quality of the network can now be logged
and weak points can be prophylactically uncovered.
Like all AS-Interface devices the analyser is interoperable, that means it can be
used in network with products from different manufacturers.
3.2
Version 2.0
The version 2.0 of the analyser brings a whole set of new possibilities apart from
many improvements in the detail: definition and disposition of "consecutive errors"
for a more rational evaluation of telegram repetitions, default-settings and offline-
execution of the protocols, analog data output, function as safety monitor in the tra-
ce mode and finally an optimized operator guidance which allows also users with
smaller experiences with AS-Interface to penetrate into the range of the "expert-
mode".
3.2.1
Manual
The manual is structured into four major chapters, which addresses different
users.
Chapter 4 Quick Start
For well experienced users who are familiar with AS-Interface or users who need
a fast result without loss of time.
In this chapter we describe the fast installation and directly usable functions. Spe-
cial cases and detailed descriptions will follow in the next chapters.
Chapter 5 Features and Functions
For users, who want to understand all functions of the analyser, or users who want
detailed information about specific functions. This description presupposes only
basic knowledge of AS-Interface.
For each function first the principle and then the possible result is described. After
this a detailed description from the procedure will follow. Possible causes for an
unexpected behavior of the network or the analyser will be discussed.
Chapter 6 Evaluation of Telegram Repetitions
AS-Interface is extremely fault tolerant. The analyser shows all telegram repetiti-
ons in the network, however, they must not be necessarily interpreted and elimi-
nated as "errors".
Subject to reasonable modifications due to technical advances.
