Specification AS-i Safety at Work
AS-i Safety at Work combines safe and non-safe data on a bus system in mixed mode. The designation AS-i
Safety at Work indicates safe transfer for integrating protective equipment in an AS-i network.
The components for AS-i Safety at Work are compliant with EN 50295 and compatible with all other AS-i
components. It is therefore easy to add safety-related functions to existing AS-i applications.
AS-i Safety at Work always requires a safety monitor (as an individual unit or integrated into a gateway), which
analyses the safe signals in the bus, and a safe AS interface bus interface that allows safe signals from safety-
relevant components to be transferred (AS-i SaW input).
Decentral safe AS-i SaW outputs are also possible. These are controlled by the safety monitor and can switch
off actuators safely.
Several safety monitors and safe input and output slaves can be used in one AS-i system. Parameters can be
set on the safety monitors, and AS-i and configuration software provide the safety monitors with a diagnostic
capability.
Important:
With the AS-i Safety at Work it is possible to meet safety requirements up to Category 4 in accordance with
EN 954-1 as well as performance level "e" in compliance with EN 13 849 and SIL 3 in accordance with EN
62 061.
All connected components, e.g. the safety monitors, safe bus interfaces and the connected sensors, must
meet these standards in order to be rated in these safety categories.
