General Information
This operating instruction is for use with the following devices of the Fuchs
GmbH:
• VAG-PB-KF-R4
The AS-i/PROFIBUS-Gateways serve to connect the Actuator-Sensor-Interface to
the PROFIBUS-DP. A gateway represents the master for the AS-Interface and the
slave for the PROFIBUS.
The AS-i/PROFIBUS-Gateway is constructed as a PROFIBUS DP slave only. It sup-
ports all PROFIBUS transmission rates up to 12 MBaud.
All AS-Interface functions can be called via the Profibus. There are three operation
modes for the data exchange with Profibus-DP: the easy mode, the advanced mode
and the professional mode. In the
easy mode
, the gateway uses a fixed I/O-configu-
ration for the Profibus and the gateway can be put into operation very easily without
further parameterization on the Profibus master. In the
advanced mode
, the size of
the I/O window can be matched to the actual structure of the AS-i network. The AS-i
master is configured by the Profibus master. During operation, AS-i parameters can
be transmitted to the AS-i slaves. Also the mini-PLC AS-i Control is accessible. All
AS-i Control functions are available (program download, upload, start, stop, read and
write user memory). The
professional mode
is the advancement of the advanced
mode. With its management channel it is additionally possible to execute further AS-i
commands via Profibus. Furthermore you can operate the advanced AS-i diagnosis
via Profibus.
The scope of delivery includes several GSD-files to ensure the easy putting into op-
eration in each operating mode. In contains also the Siemens type files version 4.0
(German) and 5.x.
All devices contain the integrated mini-PLC AS-i Control for the fast distributed pre-
processing of AS-i data. Furthermore advanced AS-i diagnosis functions are imple-
mented to locate sporadically occurring configuration errors and to judge the quality
of the AS-i communication.
All devices are delivered together with the AS-i Control Tools, a Windows software for
the easy putting into operation of the AS-Interface and the programming of AS-i Con-
trol. The software communicates via the serial interface of the PC without additional
expensive hardware. Merely a Profibus converter is needed to connect the RS232 in-
terface of the PC with the Profibus interface of the AS-i/PROFIBUS Gateway.
If no PC is available the putting into operation, troubleshooting and setting up of the
AS-i parameters can be accomplished with the use of two push-buttons, the display
and the LEDs directly on the device.
