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.

Every Safety at Work configuration must specify a restart condition.  Once the safe input conditions are true, the restart conditions determine if and how the safe outputs are activated.

  • - Automatic start -- The safe outputs will activate as soon as all input conditions have been released
  • - Monitored start -- This condition monitors the state of an input or output and uses this data bit to restart the safe outputs. It is possible to utilize a safe signal as a restart condition.  The latest Safety Monitors support restart conditions based on virtually any kind (and complexity) of restart condition.
