Figure 412: Setting example with PTP synchronization
Settings on the local HMI under Main menu/Configuration/Time/
Synchronization/TIMESYNCHGEN:1/IEC61850-9-2:
• HwSyncSrc: is not used as the SW-time and HW-time are connected with each
other due to PTP
• SyncLostMode : set to Block to block protection functions if time
synchronization is lost or set to BlockOnLostUTC if the protection functions
are to be blocked when global common synchronization is lost
• SyncAccLevel: can be set to 1μs since this corresponds to a maximum phase
angle error of 0.018 degrees at 50Hz
Settings on the local HMI under Main menu/Configuration/Communication/
Ethernet configuration/Access point/AP_X:
• Operation: On
• PTP: On
