Operating Instructions
5.7 Time synchronization
5.7.1 Relative synchronization
The transmission of the time from the PC to the SYNCHROTACT device takes place
once, with the aid of SynView, during commissioning.
The connection of pulse synchronization (ClockIN at the connector –X1) detects the
rising edge of the pulse, which is rounded to the entire second. The pulse intervals
should be therefore 1 s or the multiples of it (1 min, 1 h, 1 day).
5.7.2 Absolute synchronization
Periodic transfer of date and time from clock to SYNCHROTACT 5 – device via serial
interface: 9-pole SUB-D-connector -X2 'Time Sync.'
Pin assignment: see Technical Data
Protocol: RS 232
Reference clock: Hopf type 6870.
5.7.3 Absolute synchronization by means of the IEC 61850 - interface
Periodical transmission of date and time from SNTP-Server to the SYNCHROTACT 5 -
device over the IEC 61850 – interface.
The adjustment is made by the configuration Tool "SYN61850Config".
The IEC 61850 – interface contains a clock. Upon release ("Enable"), the clock in the
Note
synchronizing part will be overwritten even when no SNTP-Server is connected.
