Fast start-up

With Fast Start-up, PROFINET allows the implementation of modular concepts without a waiting period.

Tool change in roboter applications is easy and uncomplicated with PROFINET and Fast Startup.

The Fast Start-Up function allows rapid start-up of PROFINET Devices that are connected to SIMATIC Controllers. The communication connection between the controller and the device is established in less than a second. Thus, in modular plants, individual parts of the plant can be coupled and decoupled in minimal time. A concrete example application: Tools in robotic applications are changed significantly faster.


  • With Fast Start-up, PROFINET has a mechanism that identifies devices and connects them to the IO controller in less than 500 ms.


  • Quick detection of PROFINET devices by the controller allows modular concepts without waiting periods.

  • Automatic tool changers work faster and are more productive.
