All AS-i functions can be used cyclically as well as acyclically via PROFIBUS DP/
V1.
For the cyclical data transfer up to 32 bytes of I/O data can be transferred as bi-
nary data for one AS-i network. Additionally, analog signals and all available com-
mands of the new AS-i specification can be transferred via the command channel
through PROFIBUS.
On the serial PROFIBUS Master AS-i Control Tools can be used to monitor the
AS-i data online via PROFIBUS DP/V1.
2.2 Brief description
The actuator-sensor interface (AS-i) has established itself as a system for net-
working primarily binary sensors and actuators at the lowest level of the automa-
tion hierarchy. The high number of installed systems, the ease of use and the reli-
able operating behaviour also make the AS-i interesting in the area of machine
safety.
The safety AS-i system is intended for safety applications up to Category 4/
SIL 3. Mixed operation of standard components and safe components is possible.
The AS-i/Gateway with safety monitor monitors within an AS-i system the safe
slaves which have been assigned according to the configuration specified by the
user with the configuration software. In the event of a stop request or a defect, the
AS-i/Gateway with safety monitor switches off the system in protective operation
mode with a maximum reaction time of 40 ms.
