AS-i Safety Monitor for 2 AS-i circuits
General
The
safe
AS-i system is intended for safety applications up to Category 4/SIL 3.
Mixed use of standard components and safety components is possible.
The AS-i Safety Monitor performs monitoring within an AS-i system of the user-
assigned safety slaves based on the configuration the user has set using configu-
ration software. In case of a Stop request or a fault condition, the AS-i Safety Mo-
nitor safety shuts off the system with a response time of maximum 40 ms.
