Time synchronization

The options for time-synchronizing the REB500 to an external source are listed in
Section
These options can be selected using the HMI500 menu item, Settings/Time/Time
Synchronization.
4.7.1

Synchronizing using IRIG-B

Electrical IRIG-B synchronization is supported using the X1008 connector on the central unit.
Table 29: Connections for synchronizing with electrical IRIG-B
Connector
X1008.06
X1008.07
X1008.13
X1008.14
Optical IRIG-B synchronization is supported using the Rx-interface X1010 on the central unit.
4.7.2

Synchronizing using PPS

Synchronization via PPS is supported both via an electrical or an optical pulse.
Electrical synchronizing impulses use the interface X1008 on the central unit.
Table 30: Connections for synchronization using electrical PPS
Connector
X1008.06
X1008.13
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.
4.7.3

Synchronization by SNTP

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.

Technical manual
4.7.2, and Section 4.7.3.
Using IEC 61850 station bus communication requires the use of SNTP as an
overall synchronization method for valid timestamps and qualities.
