Time Synchronization
Time Synchronization
TimeSync
The user has the possibility to synchronize the device with a central time generator. This offers the following
advantages:
The time does not drift off from the reference time. A continuously accumulating deviation from the reference
time thereby will be balanced. Also refer to the chapter Specifications (Tolerances Real Time Clock).
All time synchronized devices operate with the same time. Thus logged events of the individual devices can be
compared exactly and be evaluated in conjunction (single events of the event recorder, disturbance records).
The device's time can be synchronized via the following protocols:
IRIG
-
B
SNTP
Communication protocol Modbus (RTU or TCP)
Communication protocol IEC60870
-
5
-
103
Communication protocol DNP3
Protection communication (only for line differential devices and only for one of the two interconnected devices).
The provided protocols use different hardware interfaces and differ also in their achieved time accuracy. Further
information can be found in the chapter Specifications.

IRIG-B
IRIG

Recommended, if interface available
SNTP
RJ45 (Ethernet)
Recommended alternative to IRIG
-
B, especially when using
IEC 61850 or Modbus TCP
Modbus RTU
RS485, D
-
SUB or
Fiber Optic
Recommended when using the Modbus RTU communication
protocol and when no IRIG-B code generator is available
Modbus TCP
RJ45 (Ethernet)
Limited recommendation when the Modbus TCP communication
protocol is used and no IRIG-B code generator or an SNTP server
is available
IEC 60870
-
5
-
103
RS485, D-SUB or
Fiber Optic
Recommended when using the IEC 10870
-
5
-
103 communication
protocol and no IRIG
-
B code generator is available
DNP3
RS485 or RJ45
(Ethernet)
Limited recommendation when using the DNP3 communication
protocol and no IRIG
-
B code generator or an SNTP server is
available
ProtCom
X102 (Fiber Optic)
The “ProtCom” Protection Communication is available only with line
differential devices, and it connects two devices with each other.
Time Synchronization via “ProtCom” is recommended for only one
of these two devices. (Time Synchronization of the other device
should be done via another protocol, e. g. IRIG-B or SNTP.)
