Pepperl+Fuchs Podcasts


Pepperl+Fuchs’ TechTalk helps listeners gain an insight into modern automation technologies by focusing on AS-Interface (Actuator Sensor Interface) and its associated safety technology, Safety at Work. TechTalk covers topics that range from hardware selection to installation and maintenance. Control engineers familiar with AS-Interface will get the latest news on specification enhancements, hear about new products, and familiarize themselves with established and cutting-edge troubleshooting methods, tips, and tricks.  Users who are interested in applying these technologies will learn what it takes to set up an AS-Interface system, how Safety at Work improves safety systems, and why those technologies have the potential to save time and money during all phases of a project.

AS-Interface safe coupling -- in the past, situations where safe data had to be shared between separate independent system users used a trick, where a safe output on one AS-Interface network was connected to a safe input on another. Later, the ability to share an entire network between several AS-Interface gateways was added, allowing 31 pieces of safe data to be shared.  Recently, SafeLink was introduced allowing safe data sharing over Ethernet.  This method has many advantages:

  • --Sharing data on Ethernet frees up the shared AS-Interface network
  • --Each gateway can now share 31 safe data points
  • --The total system can use 1922 safe rated devices exchanging 961 safe data points
