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.

AS-Interface parameter bits -- This week Tim explains what AS-Interface parameter bits are. Using AS-Interface parameter bits users can configure AS-Interface modules to perform certain operations.  Users should know that the default operation of the modules have been selected to cover nearly all cases and modifying the parameter bits is only needed in rare cases.  By default the parameter bits are "1" or "ON".  Tim also explains the difference between 'parameters' and 'power-up parameters'.  Users should know that:

  • --Parameter bits are not stored on the module
  • --While the hand-held can change a parameter bit, disconnecting the module will always reset them to "1"
  • --The PLC can be instructed to send parameter bits during startup or even during normal operation
  • --Parameter bits can be set through the display on the gateway
  • --ControlTools software is another way of setting parameter bits
