Data Handling

The Data Handling tab once again contains very important setting parameters that are also suitable for fine-tuning the writing away and communication of data. For example, general settings for the packet size of the recorded data can be configured. Depending on the selected target (file or MQTT), you will receive additional or different setting parameters.

Some parameters are initially generally valid.

Autostart Stream: Specifies whether the stream should start automatically as soon as TwinCAT enters Run Mode. If this option is not chosen, the stream can be started via a PLC program.

Target:

Target Name: The targets created in the first logger level (file and MQTT) can be individually assigned here for the actual stream. A target can be used several times in different streams.

Compression:

Mode: The data compression mode can be set here. No compression and so-called delta encoding are currently available. Details on delta encoding can be found in the Data compression chapter.

Compare Width: Specifies the data comparison bandwidth in bytes that the logger checks for differences.

The other setting options depend on the selected target and are described further below for File and MQTT.
