Setting for time-tagged measurands
(iii)
For Time-tagged measurand frame in the IEC 60870-5-103 standard, event information
supplemented with numerical information are responded for Class 1 request from upper
system (station). The IED can provide event information, which is converted the numerical
information in metering table according to user setting weight, by using Time-tagged
measurand frame about the signal assigned (i.e., the Data ID).
When the "Time-tagged measurand" item is selected on the GR-TIEMS, the setting
screen is displayed.
Type ID=4 (Time-tagged measurand with relative time) can be set in this screen. In one
frame of Time-tagged measurand, the INF, FUN, Sig No., Rev, COT and SCL must be set
and the maximum eight frames of Time-tagged measurand can be set. The information
number of the frame is determined by the INF setting. The most left item "No." is only serial
number and can be skipped.
Common address is linked with the address setting† in the IED.
†For more information, see
1118).
In the transmission format of Type ID=4 (Time-tagged measurand with relative time),
customized items are shown in Table 11.5-9.
