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.

Last week, Tim and Helge talked about the Safety at Work protocol and mentioned the Safety Monitor. In this episode, they discuss what the Safety Monitor does and why it is necessary.

  • - What is a SafetyMonitor?
  • - What is safety logic?
  • - How many safety devices per network
  • - Replacing a failed Safety Monitor (see...

AS-Interface is designed from the ground up to be noise resistant. The flat cable makes it easy to use even in wet applications.  Still, it is not uncommon for installers to make mistakes that can easily be avoided.

  • - Differential signals and symmetry
  • - Ground faults
  • - Properly installing AS-Interface
