The AS-i/PROFIBUS-Gateways serve to connect AS-Interface systems to the
PROFIBUS. They act as a Master for the AS-Interface and as a slave for the
PROFIBUS.
New AS-i Specification 2.1
The AS-i/PROFIBUS-DP Gateways already fulfil the new AS-i Specification 2.1.
This means:
• Up to 62 AS-Interface slaves can be connected per 1 AS-i network
• The transfer of analog signals via AS-i is integrated in the Masters
• All further functions of the new specification as e.g. the diagnosis of the AS-i pe-
ripheral fault are implemented.
All AS-i functions are provided cyclically via PROFIBUS-DP V0 and acyclically via
PROFIBUS-DP V1.
In the cyclic data transfer optionally up to 32 bytes I/O data are transfered for the
binary data of 1 AS-i network. Furthermore analog signals and all further com-
mands of the new AS-i specification can be transferred in the management chan-
nel via
PROFIBUS.
The serial PROFIBUS Master (art. no. 1258) and the AS-i Control Tools can be
used for the monitoring of the AS-i data online via the PROFIBUS-DP V1.
Advanced Diagnostics
Diagnostics, which go far beyond the standard diagnostics facilitate the simple de-
tection of the occassionally occuring configuration errors and further irritations to-
