Safety and standard components in one network

AS-Interface Safety at Work

AS-Interface Safety at Work is a safety-related extension of the AS-Interface and is simply integrated in an existing AS-Interface network. All standard and safety components are activated in parallel via the same cable so that you can integrate safety-related functions such as an EMERGENCY STOP or door monitors in your existing system.

In order to evaluate safety-relevant signals, you will only require one additional safety monitor that uses dynamic code sequences to reliably communicate with the Safety at Work components. Installing an AS-Interface guarantees compliance with safety category 4 according to EN 954-1 and SIL3 according to IEC / DIN EN 61508.

Clear benefits of "AS-Interface Safety at Work":

  • Only one bus line required to transfer safe and unsafe data
  • Fully compatible with all standard AS-Interface devices
  • No special communication mechanisms required
  • Diagnosis of safe modules possible via a standard AS-Interface master
  • Category 4 requirements specified in EN 954-1 and IEC 61508 are fulfilled
  • Secure input card in the process computer (PLC) not required
  • Easy parameterization using special configuration software on the PC
