Basic IED functions
To receive IRIG-B there are one dedicated connector for the IRIG-B port. IRIG-B 00x messages can
be supplied via the galvanic interface, where x (in 00x) means a number in the range of 1-7.
If the x in 00x is 4, 5, 6 or 7, the time message from IRIG-B contains information of the year. If x is
0, 1, 2 or 3, the information contains only the time within the year, and year information has to
come from the tool or local HMI.
The IRIG-B input also takes care of IEEE1344 messages that are sent by IRIG-B clocks, as IRIG-B
previously did not have any year information. IEEE1344 is compatible with IRIG-B and contains year
information and information of the time-zone.
It is recommended to use IEEE 1344 for supplying time information to the IRIG-B module. In this
case, send also the local time in the messages.
Synchronization via DNP
The DNP3 communication can be the source for the course time synchronization, while the fine
time synchronization needs a source with higher accuracy. See the communication protocol
manual for a detailed description of the DNP3 protocol.
Synchronization via IEC60870-5-103
The IEC60870-5-103 communication can be the source for the course time synchronization, while
the fine time synchronization needs a source with higher accuracy. See the communication
protocol manual for a detailed description of the IEC60870-5-103 protocol.

Time tagging resolution, events and sampled measurement values
Time tagging error with synchronization once/min (minute pulse synchronization),
events and sampled measurement values
Time tagging error with SNTP synchronization, sampled measurement values

16.4.1 Functionality
Use the four sets of settings to optimize the IED operation for different system conditions.
Creating and switching between fine-tuned setting sets, either from the local HMI or configurable
binary inputs, results in a highly adaptable IED that can cope with a variety of system scenarios.
