Synchronization using BI signal
(iii)
When accurate1Hz square-wave can be supplied as a reference clock, the clock function can
make the time synchronization. The 1Hz square-wave is transferred using a binary input
circuit (BI).
Example of time synchronization with a BI circuit
Figure 5.8-7 exemplifies that the 1Hz square-wave is inputted at the BI1†.

†Note: It is just used for the explanation; hence, another BI circuit should be selected in
accordance with wiring cables. For more information of the BI circuit, see Chapter
5.6.
Setting procedure
The user should make the following steps in respective IEDs.
1) Set BI for the setting [Time Sync Src]; then set On for the setting [BI-SYNC].
2) Check BI is shown under the ActivSyncSrc, as shown in Figure 5.8-8.
3) Set a Data_ID for setting [BI_ID]. For example, as shown in the Figure 5.8-7, when
the user wishes to inject the signal at the BI1 on the IO#1 slot, the user should set
