With AS-i Safety at Work, a certified standard has been developed that permits the use of safety-ori-
ented components (e.g. MS6(N)-SV-...-E-ASIS) in the AS-i system. The safe AS-i system is intended for
safety applications up to category 4 in accordance with EN ISO 13849-1 PL e.
Mixed operation of standard components and safety-oriented components is possible. The AS-interface
master considers the safety-oriented slaves just like all other slaves and incorporates them into the
network. The transmission protocol and cables in the AS-i system are laid out so that they are also
capable of transmitting safety-oriented telegrams.
The AS-i safety monitor is the central safe component and monitors the safety-oriented slaves assigned
to it within an AS-i system. The safety function is ensured via additional signal transmission between
the safety-oriented slaves and the AS-i safety monitor. This transmission takes place with a special
safety protocol.
In the case of a stop request or a defect, the AS-i safety monitor in protection mode reliably switches
the system off with a reaction time of maximum 40 ms.
