Configuration Of The As-I Network - Pepperl+Fuchs VAG-PB-KF-R4 Manual

The AS-i flags and every AS-i slave take up four bits. The meaning and allocation of
these bits is explained in the appendix, chapter 11.3.2.
If the AS-i flags shall not be used, you have to make sure that by all
means these four bits are set to zero.
Bit allocation AS-i parameters: see appendix, chapter 11.3.2.
Constants for the control byte in the DP-telegram's AS-i Control part: see appendix,
see chapter 11.3.3.

8.2.2 Configuration of the AS-i Network

During the building up of the connection to a Profibus-DP master, the AS-i network is
configured via the Profibus. The AS-i configuration does not have to be stored locally
(via the push buttons mode and set or the AS-i Control Tools). Merely the AS-i slaves
have to get the designated addresses.
The AS-i/PROFIBUS Gateway compares the nominated AS-i configuration received
from the DP-master with the actual configuration of the AS-i network. If they match,
the gateway does data exchange on AS-i. (This does not affect the data exchange on
Profibus).
The AS-i configuration data of the AS-i slaves (ID-code and I/O-configuration) should
be known before configuring the DP-master. You find them in the AS-i slave's docu-
mentation.
The configuration via Profibus-DP offers the following advantage: The
AS-i configuration data of the AS-i network is stored in the DP-master.
This way, an immediate start-up without any need for manual interven-
tion is possible when exchanging the gateway (one exception is the
Profibus station address).
8.2.3 Configuration of the Profibus-DP Master
To project the Profibus-DP network you have to copy a GSD-file (enclosed on dis-
kette) to the working directory of your Profibus configuration software (some pro-
grams have a directory named GSD, where the GSD-files have to be copied to,
please see the manual of the used software). Depending on the software you may
have to dispatch a command like „read GSD-files".
The GSD-files can be found on the enclosed diskette „AS-i/PROFIBUS-Gateway IBM
PC Software" in the directory \GSD.
For the advanced mode the following GSD-files are available:
bwas1742.gsd
device: AS-i/PROFIBUS-DP Gateway,
model name in the GSD-file: „AS-i/DP-A"
If the Profibus configuration software needs the older type files instead of the GSD-
files, please read the file \gsd\readme.txt on the enclosed diskette.
Subject to reasonable modifications due to technical advances.
