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.

LEDs are powerful diagnostic indicators on just about all AS-Interface devices. The simple rule is that "green" is good and “red" requires someone’s attention.  Outputs are an interesting exception where "amber" indicates that the output is ON.  The AS-Interface Maintenance and Service Guide(PDF) also lists the LED states on the "consortium" Safety Monitor.
