AS-interface Safety at Work combines safe data and data that is not
safe in mixed operation in one bus system. The term AS-interface
Safety at Work identifies here the safe transmission for the integra-
tion of protective devices in an AS-interface network.
AS-interface Safety at Work components are, in compliance with
EN 50 295 and IEC 62 026-2, compatible with all other AS-interface
components. Existing AS-interface applications can therefore be
straightforwardly extended with safety-relevant functions.
AS-interface Safety at Work always requires a safety monitor that
evaluates the safe signals in the bus, and a safe AS-interface bus-
node that makes it possible to transfer safe signals from safety-
relevant components.
There are two types of safe AS-interface busnode:
safe busnodes to which safety-relevant components, e.g. ESPE,
emergency stop buttons or safety door switches can be connected
safety-relevant components with already integrated
AS-interface Safety at Work interface
Several safety monitors and up to 31 safe busnodes can be used in
an AS-interface system. The parameters for the safety monitors can
be set and diagnostics can be performed using the AS-interface and
configuration software.
With AS-interface Safety at Work, safety requirements up to category
4 in compliance with EN 954-1 can be met.
For categorisation in these category, all components connected, e.g.
the safety monitors, the safe busnodes and the sensors connected
must comply with the corresponding safety-relevant standards.
