2. Waveform Capture Group
Waveform Capture can log up to8 groups of waveform data. When the 8 group
data is full, it does not respond to any waveform triggering condition. Only
when all the waveform data is reset / emptied, waveform capturing function will
be normal. When the waveform data is emptied, new waveform data starts from
the 1st group. The waveform data will not be lost when the power is off.
Note: since the amount of each waveform group data is large, it takes more time
to write into the flash memory. Therefore, Waveform Capture only responds
to one triggering condition at one time. During the process of writing data
into the flash memory, it does not respond to new triggering condition. After
the process of memory writing, it will respond to new waveform triggering
condition.
3. Waveform Capture Triggering Condition
1) Manual Triggering
Manually trigger one group waveform capture.
2) DI Triggering
DI Triggering must fulfill the following two conditions at the same time.
•IO modules with the logical address of 1 (AXM-IO11, AXM-IO21, AXM-IO31).
•DI channel type is set as “State”.
The Modbus address assigns two bits for the DI channel. When they are set
as “00”, it means DI Triggering Disabled; “01” means DI Triggering will be
implemented when DI state changes from OFF to ON; “10” means DI Triggering
will be implemented when DI state changes from ON to OFF; “11 “means DI
Triggering will be implemented when DI state has any change.
3) Voltage Sag Triggering
As mentioned in Voltage Sag event logging, when Voltage Sag Triggering
