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.

Usage example -- This week, Robert talks about a specific AS-Interface application involving the safety encoder.  The video "Using a Safety Encoder on AS-Interface" goes through the configuration and setup of the system. The AS-Interface system covers the following operational situations:

  • --When all gates are closed...

Hardware -- The safety speed monitor evaluates data from the safe-rated encoder. In a nutshell, the safety speed monitor evaluates the sine/cosine signals from the encoder, and determines if the speed is within limits and if the direction of rotation is what it should be.

AS-Interface application -- Many types of automation systems can benefit from safe-rated encoders. These rotary encoders may be used within an AS-Interface safety system. In a typical application, the safety encoder is used to safely determine the velocity of a rotation.  Being able to safely know when a machine has...

AS-Interface Safety Monitor -- The Safety Monitor is the safety controller of an AS-Interface Safety at Work system. As a PL e rated device it is able to be used in the most demanding safety applications. The VAS-2A8L-KE4-8SE Safety Monitor introduced here can process safety date data from up to 31 safe rated...
