"Periodic commands"
If the device receives periodic Modbus com-
mands for synchronization, there are different
scenarios.
Scenario "Command 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
Pulse
Time base
end
Capture time
Scenario "Command according to 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
Pulse
Time base
end
Scenario "Command 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
Pulse
Time base
end
INFORMATION
With periodic synchronization, the time is synchro-
nized with each command!
