PDO assignment	: Specific CoE commands for initializing the `0x1cxx` objects are generated and written to the slave.
PDO configuration	: The CoE commands for `0x16xx` or `0x1axx` are generated, loading the PDO mapping to the slave.As a rule, the default values originate from the ESI file and the device must support this functionality.For example, if a device has a fixed configuration, then these commands are seen as flawed.
Load PDO info from the device	The current PDO configuration is read from the slave and entered into the configuration. The lists in the upper and lower right are then deleted and filled with the read data. This is especially useful when the ESI file is incomplete and the configuration is available only on the slave.
