§5.4 – Device Options

Incorporating PROFINET into your device means modularity and flexibility. Start simple and add functionality as required. There are features that some manufacturers will desire to be integrated, and others will not. Some examples of these optional modules include:

  • Fast Startup (FSU): IO Devices go instantly into a ‘power on’ state in response to signals from an IO Controller.
  • Network Redundancy: Redundancy configuration with ring topologies for high availability systems.
  • PROFIsafe: Application Profile for the implementation of functional safety with less effort, cabling, and maintenance. Further information can be found under the PROFIsafe section.
  • PROFIenergy: Application Profile developed to save energy and reduce utility bills; it is built on top of the existing PROFINET protocol. PROFIenergy is discussed in depth in the Features section.
