FSU capability

Hello,

I want to run a fast startup for a profinet IO device for quick change application.

I can't find any information about which CPUs that supports FSU functionality.
I'm aware that profinet IO device also must have a FSU functionality.

On top of that, how do I activate it from software?
Is it only by "prioritized startup" option?

Best regards,
Paul

Hi Paul,

Although I am not quite sure, Fast Start-up (FSU) as defined in the PROFINET standard should be covered by the prioritized startup feature. The list of devices that support this and other features can be found in the FAQ "Which IO controllers and IO devices support the following functions in STEP 7 (TIA Portal): IRT, prioritized startup, MRP, MRPD, PROFIenergy, Shared device, MSI/MSO, I device, clock-synchronized mode, system redundancy and option handling?".

More information about prioritized startup can be found in the function manual "SIMATIC PROFINET PROFINET with STEP 7".

Kind regards
Stefan
