Neighborhood detection in Step 7 takes place using a port assignment:
• BUS IN corresponds to port 1 (X1 P1).
• BUS OUT corresponds to port 2 (X1 P2).

General information about the GSD file
The functionality of the AMS 348
i
is defined via an XML-based GSD file. The GSD file is the
same for all AMS 348
i
and forms a mandatory part of the device. The GSD file has a modular
architecture and contains all the functions of the AMS 348
i
in modules.
The AMS 348
i
offers 17 different modules. Each of these modules can only be activated once
per AMS.
The AMS 348
i
checks its max. permissible number of modules. The control also reports an
error if the input and output data across all modules exceed a total length of 1024 bytes.
The specific limits of the individual modules of the AMS 348
i
can be stored in the module
description and in the GSD file.
Note!
You can find the current GSD file for the
AMS 348
i
on our homepage at: www.leuze.com.
The participant (here AMS 348
i
) is configured via the GSD file with a user-specific configu
-
ration tool such as the Siemens Simatic Manager.
The exchange of data and the configuration of parameters is organized by means of the GSD
file.
All the parameters of the AMS 348
i
are preset default values. These can be altered,
depending on the application. The user activates only the modules from the GSD file whose
parameters should be changed or whose input/output data are to be read.
For this purpose, the corresponding module from the GSD file is activated and configured or
prepared for control and reading of inputs and outputs.
All parameters and accesses to the AMS 348
i
are thus stored in the control. If necessary,
the configuration is written to the AMS according to predefined control criteria.
Note!
On the AMS 348
i
, parameters can for test purposes be changed via the display. As soon as
parameter enable is activated on the display, the AMS 348
i
is deactivated on the PROFINET.
All the parameters set via the GSD file initially remain active in the AMS 348
i
. Parameter
changes can now be made via the display for test purposes. If parameter enabling is deac
-
tivated via the display, only the parameters entered in the PROFINET modules and the
PROFINET default settings are in effect.
Parameter changes made via the display are no longer in effect on the PROFINET!
