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 is a floating communication network and neither one of the two leads [AS-Interface + or AS-Interface -] is connected to ground.  If this happens, the network has a ground fault, reducing the ability of the installation to deal with electromagnetic noise. Related to this is an important feature of our AS-Interface gateways giving them the ability to track communication errors.

  • --Make sure the (+) and (-) terminals of the power supply are not grounded
  • --Don't introduce ground faults along the network (pinched cables for instance)
  • --Always use the built-in error counter feature to gauge the quality of the installation
  • --Don’t forget to reset those counters to get a reliable relative error measure over time
