1.10 Connection to the higher-level control
SIRIUS Innovations
88 System Manual, 01/2011, A8E56203870002-03
SIRIUS switching devices are connected to the automation level via AS-Interface or IO-Link,
without any additional wiring. These interfaces ensure that information about the switch
position and the readiness of the feeder for operation is transferred, and that contactor
control is implemented. In addition to these three items of information relating to feeders, IO-
Link also transfers diagnostics data.

Figure 1-40 Communication via AS-Interface or IO-Link
SIRIUS 3RA27 function modules or SIRIUS 3RA6 compact starters can communicate with a
higher-level control either via the AS-i fieldbus or via the IO-Link wiring system. Cyclic data
transmission (DIs and DOs) is identical for both IO-Link and AS-i.
