DC synchronous oversampling operation
In oversampling mode, it is possible to acquire up to 5 measured values in one bus cycle, enabling the
acquisition of rapidly changing measured values.
For n-times oversampling, one of the DC synchronous operating modes with the desired factor n is selected
in the EtherCAT slave setting.
Example:
-
DC- Cycle time 4000µs
-
4-times oversampling
Every 1000µs the Sync 0 interrupt is triggered on the module, in which the input values are read.
These are available in the following objects:
Field Value (Real)
Process Value (Real)
Furthermore, every 4000µs the Sync 1 interrupt is triggered, with which the output values are written and the
average value of the sampled input values is calculated.
