8.3.5 Trigger settings for PLC programming
If the PLC program instructs the operation of the disturbance recorder, the user should set the
[Trigger ID1] to [Trigger ID4]. That is, the program-output points should be set for the settings
[Trigger ID1] to [Trigger ID4]; then, set On for the [Trigger SW1] to [Trigger SW4], respectively.
8.3.6 Screen information
Figure 8.3-2 indicates the maximum number of the recording operations as the number is
changed depending on the time settings, which are shown in Table 8.3-1. Figure 8.3-3 shows
the operation time and the date for the disturbance recorder and the figure illustrates five
disturbance phenomena have been memorized in the IED.

Figure 8.3-3 Detail information in the disturbance recorder
The information in the disturbance recorder is managed in the COMTRADE format,
hence, the user can transfer the disturbance recording file to the PC using the engineering tool
‘GR-TIEMS’. Figure 8.3-4 shows the example of the GR-TIMES screen. For more information,
