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.

Just as important as stopping a machine is the restart process.  Safety at Work offers a lot of flexibility.  In addition to the start conditions discussed last week, activation is similar to a restart condition with relaxed timing conditions.

  • - Activation -- In situations where the timing required by the monitored start is a problem, the "level-based" Activation can be considered
  • - Local Acknowledgment and Flip-Flop -- these two functions add another level of flexibility when it comes to restarting a system.  These functions will be discussed in detail at a later stage.
