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.

In this episode, Helge and Tim run down the list of the six most important AS-Interface benefits - explained in about one minute each:

  • --2-conductor cable – Easy to run, low cost, fast installation, no expensive connectors.
  • --Topology-free – Run cable anywhere in any shape to simplify layouts and make planning easy when you add another module during install. Just keep in mind that a segment must be 100 m or less.
  • --Open technology – 350 vendors offer just about anything from stack lights to safety door switches to motor starters ... and of course lots of I/O modules.
  • --Fast and deterministic – Let's take a gateway with two fully loaded AS-Interface networks, that is, 496 inputs and up to the same number of outputs. All these outputs will be updated in 20 ms guaranteed. Inputs are even faster. Those take just 10 ms. Reduce the number of I/Os and the system updates even faster.
  • --Supports just about any network and any PLC – Switch complete I/O infrastructure from one PLC brand to another in no time.
  • --Build really large networks – If a 100 m segment is not enough, just add a second or third or fourth and create really large networks easily.
