“Periodic pulses"
If the device receives periodic pulses via digital
input 3 or periodic Modbus commands, there are
different scenarios.
Scenario “Pulse outside the capture time":
·Summed intermediate values are set to 0.
·The time is set to 0 (new relative zero point).
·There is no value calculation.
Scenario “Pulse after time base, but within the
capture time":
·Summed intermediate values are set to 0.
·The time is set to 0 (new relative zero point).
·There is no value calculation.
Scenario “Pulse before time base, within the
capture time":
·Perform value calculation now.
·The time is set to 0 (new relative zero point).
·Delete summed intermediate values.
NOTE
With periodic synchronization, the time is synchro-
nized with each pulse!
