Data bytes

Data for configuration, security value and PCP are determined with the aid of the module-specific data
sheets.

Parameterise the configuration data (measuring range, sensor type ...) on device start-up.

You can only re-parameterise via acyclical services in the data exchange mode.

*

"?" is a placeholder for those bytes which could not be named as a package in the run-up. The

bytes are counted consecutively, so therefore the naming is oriented among other things to the
number of data bytes and the presence of individual blocks.
