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.

What if automatic node replacement fails? AS-Interface gateways typically offer automatic node replacement indication when the function is available. If the AS-Interface gateway does not turn this indication on, it means that this function is simply not possible. Reasons include:

  • -Auto addressing has been disabled (through the PLC or display)
  • -Gateway is not in Run mode (PRJ LED is illuminated on Pepperl+Fuchs devices)
  • -More than one module failed; Pepperl+Fuchs gateways do allow automatic multi-node replacement
  • -Replacement module not at ADR=0
  • -Replacement module is not identical (listen to episodes 35 - 39 for additional help)
