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 repeaters are a simple way to extend the total length of a network by allowing multiple segments to be put together.  AS-Interface repeaters do not have an address and are transparent to user.

  • --Remember to power the new segment (after the repeater); use exactly one power supply per segment
  • --Make sure that no module is more than two repeaters from the gateway
  • --Consider extending the network by running it in "both directions" from the gateway; this allows 500 m networks without violating any rules
  • --Consider using terminators if additional length is necessary. Think about the voltage drop.
