Timestamp Distributed Clocks - Beckhoff EL34 Series Documentation

Commissioning
Reference channel for the frequency measurement (index 0xF800:11 [} 159] and index 0xF800:13
[} 159])
The EL34xx can measure the frequency for a voltage path input signal and a current path input signal. CoE
objects "Reference" and "Frequency Source" (F800:11 and F800:13) can be used to set which frequency is
to be output as PDO.
Default: Voltage at channel 1
Power quality factor setting
To adapt the power quality factor to your mains supply, enter the nominal voltage and frequency in CoE
object "0xF801 PMX Total Settings PQF [} 159]". This can also be done via the "Settings" tab, which
summarizes all the important terminal setting options in a user-friendly manner.

Timestamp Distributed Clocks

The terminal transfers the time of the voltage zero crossing as timestamp to objects 0x6006:12 [} 186]
(channel 1), 0x6016:12 [} 186] (channel 2) or 0x6026:12 [} 186] (channel 3), if the corresponding indices
0x1A04 [} 198], 0x1A0E [} 198] or 0x1A18 [} 198] are enabled.
