Distributed Clocks mode

In the Distributed Clocks mode (DC mode), the precise timestamp is recorded for each measured value and transmitted to the controller as cyclic process data. To this end

• DC must be activated. To do this, select DC-Synchron (input based) on the "DC" tab
  
• The PDO x1A03 in the Process data management is to be activated in the SyncManager 3 "Inputs"

The EPP3356-0022 operates free running with a cyclic, but not equidistant measurement; the time intervals between 2 measured values are therefore not constant. For this reason the 64-bit timestamp delivered with the process value must be evaluated by the user.

In order to suppress falsification of the measurement results by upstream filters, both the software filter and the averager are deactivated in this operating mode. The measurement/calculation and provision of the measured value in the process data therefore takes place at the conversion rate corresponding to the mode: 10.5 kSps or 105.5 kSps

Time stamp
