1.5.10 Communication
SIRIUS switching devices can be connected to higher-level control systems using
conventional wiring, but also by means of intelligent wiring and a fieldbus:
● IO-Link
● AS-Interface
SIRIUS switching devices are linked into the Siemens Totally Integrated Automation concept
via function modules. Totally Integrated Automation offers the user uniformity in terms of
configuration, programming, data storage, and communication.
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.
