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.

Continuing their discussion of AS-Interface gateways, Tim and Helge talk about mapping I/O into the PLC. Since gateways map this I/O into a fixed map, adding or even removing modules later is trivial. Specifically on EtherNet/IP, the I/O instances make it convenient for the programmer to define how much data a gateway reserves in the PLC.
