General AS-Interface Safety at Work in safety engineering Operation of AS-Interface Safety at Work AS-Interface (AS-i) is a low-level bus system that is used for the transfer of small data volumes. It is particularly suitable where digital signals must be collected in the field. The bus is very easy to set up and does not require any special programming tools. Simple address setting of the subscribers and an As-i master are all that is needed. Any required replacement of faulty components is very easy with ASInterface Safety at Work. A faulty bus subscriber is removed from the bus during operation...
