General Information
This operating instruction is for use with the following devices of the Fuchs
GmbH:
• VAG-PB-G4F-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-configuration 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 Profi-
bus 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
profes-
sional mode
is the advancement of the advanced mode. With its management chan-
nel 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.
