Optical synchronizing impulses use the Rx-interface X1010 on the central unit.
PPS impulses are only processed when they are received at a rate of 1 s ±50 ms. An
error message is generated should this not be the case and the system switches over
to the internal REB500 clock. Valid second impulses correct the internal clock by a
maximum of ±0.5 seconds.
3.7.3 Synchronization by SNTP
Using 61850 station bus communication requires the use of SNTP
as an overall synchronization method for valid timestamps and
qualities.
To synchronize the REB500 via SNTP, at least one SNTP-server is necessary.
Redundant SNTP in case of device failure is optionally supported by specifying a
second server.

This section provides additional options for system-time parameters.
3.7.4.1 Time zone correction
This menu permits the adjustment of the deviation between local time (of installed
REB500 system) and UTC (Universal Time coordinated).
