DFTReference: The reference DFT block (InternalDFT Ref,DFTRefGrp1 or External
DFT ref) .
FreqMeasMinVal: The minimum value of the voltage for which the frequency is
calculated, expressed as percent of VBasebase voltage setting (for each instance x).
VBase: Base voltage setting.

3.4.14 Authority status ATHSTAT
3.4.14.1 Application
Authority status (ATHSTAT) function is an indication function block, which informs
about two events related to the IED and the user authorization:
• the fact that at least one user has tried to log on wrongly into the IED and it was
blocked (the output USRBLKED)
• the fact that at least one user is logged on (the output LOGGEDON)
The two outputs of ATHSTAT function can be used in the configuration for different
indication and alarming reasons, or can be sent to the station control for the same purpose.
