"Periodic pulses"
Different scenarios may result if the device
receives periodic pulses via the digital output
3 or periodic Modbus commands.

Scenario "pulse outside the capture time"
• Totaled interim values are set to 0
• The time is set to 0 (new relative zero
point)
• No value calculation occurs

Scenario "pulse after the time base, but
inside the capture time"
• Totaled interim values are set to 0
• The time is set to 0 (new relative zero
point)
• No value calculation occurs

Scenario "pulse before the time base, inside
the capture time"
• Now perform the value calculation
• The time is set to 0 (new relative zero
point)
• Delete the totaled interim values

Attention: The time is synchronized for each
pulse in periodic synchronization!
