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.

Digital I/O module -- There is a lot of information about an AS-Interface module that users can get from the data sheet. Tim and Helge go through the details on a technical data sheet for AS-Interface module VBA-4E4A-G11-ZAJ/EA2L-F, as an example.

  • --AS-Interface specification and Master spec -- This identifies to which specification the module was designed and what kind of master is required for the module.
  • --Safety-relevant data -- Even for nonsafety-rated modules, it is useful to have this data.  Most typically, it is used in SISTEMA when evaluating safety configurations.
  • --Indicators -- This includes LEDs for inputs, outputs, and all supply voltages.  Modules also indicate internal errors and peripheral errors using LEDs.
