ASIsafe – Safety is included
ASIsafe enables the integration of safety-related components such as EMERGENCY STOP pushbuttons, protective door switches, cable-operated switches or other AS‑i safety sensors in an AS‑Interface network. These are fully compatible with the familiar AS-Interface components (masters, slaves, power supply units, repeaters, etc.) in accordance with IEC 62026-2 and are operated in conjunction with them on the yellow AS-Interface cable.
Tested safety
- Protective door switches
- Cable-operated switches
- Other AS‑i safety sensors
The transmission method for safety-related signals is released for applications up to SIL 3 (IEC 62061)/PL e (ISO 13849‑1).
Higher-level control
As usual, nodes on the AS-Interface bus are controlled in operation by the standard program of the higher-level SIMATIC (F) CPU or by a SINUMERIK control.
Configuring safety functions
In order to implement safe functions, the information from the safe and standard nodes must be combined logically and further parameters set.
In conjunction with the modular safety AS-i master, which is formed by combining the CM AS-i Master ST and F-CM AS-i Safety ST modules in an ET 200SP station, all safety functions and combinations are configured via STEP 7 and processed in the controller (F-CPU) by the fail-safe program.

Integrated safety technology in the AS‑Interface system can be used anywhere where EMERGENCY STOP buttons, safety gate interlocks, safety switches, light grids and two-hand operation are installed.
