Oversampling

Function

Oversampling is the acquisition of data in constant bus cycle segments (sub-cycles). The

configured number n of sub-cycles corresponds to one PROFINET bus cycle.

Oversampling is useful whenever you require acquisition of data with high time resolution but

without using an extremely short PROFINET bus cycle and thus fast CPU cycles.

With oversampling, a PROFINET bus cycle is divided into constant bus sub-cycles:

● One measured value is acquired in each sub-cycle.

● The minimum PROFINET bus cycle is 250 µs. Only a subset of functions is available for

shorter sub-cycles.

● The shortest possible sub-cycle is 50 μs.

● You can configure oversampling:

– For channel 0 (1-channel operation)

– For channel 0/1 (2-channel operation)

● The number of sub-cycles can be set as follows:

– From 2 to 16 for one channel

– From 2 to 8 for two channels

Requirement

Oversampling is only possible when isochronous mode is set.

Configuration

You configure oversampling with the following parameter:

● Sampling rate

Note

Do not use a reduction ratio for blocks in the case of configuration with oversampling in the

runtime groups of your user program. This will ensure that the data processing in the user

program of the CPU is synchronized with the acquisition on the module.
