Time Synchronization
TimeZones
The device gives the User the ability to synchronize the device with a central time generator. This provides the
following advantages:
The time does not drift from the reference time. A continuously accumulating deviation of the reference time thereby
will be balanced. Also refer to the Specifications (Tolerances Real Time Clock) section.
All time synchronized devices operate with the same time. Therefore, logged events of the individual devices can be
compared exactly and be evaluated (single events of the event recorder, waveform records).
The device's time can be synchronized via the following protocols:
IRIG-B;
SNTP;
Communications-Protocol Modbus (RTU or TCP); and/or
These protocols use different hardware interfaces and are different in accuracy. Further information can be found in the
Specifications section.
Used Protocol
Hardware-Interface
Recommended Application
Without time
synchronization
---
Not recommended.
IRIG-B
IRIG-B Terminal
Recommend, if interface available.
SNTP
RJ45 (Ethernet)
Recommend alternative to IRIG-B, especially when using
IEC 61850 or Modbus TCP.
Modbus RTU
RS485, D-SUB or
Fiber Optic
Recommend when using Modbus RTU communication protocol and
when no IRIG-B real time clock is available.
Modbus TCP
RJ45 (Ethernet)
Limited recommendation when Modbus TCP communication protocol
is used and when no IRIG-B real time clock or SNTP-Server is
available.
