4.5.6.2 Configuration
When parameterization is complete, the master sends a configuration message to the slave. The
configuration message causes the slave to check the transmitted configuration with reference to the stored
configuration.
You can describe up to 16 bytes or words in one octet of the data unit (DU). You can group inputs and
outputs with the same format in one octet. Otherwise you must use a separate octet for each individual
byte/word.
The configuration message from the master to the interface module is structured as
follows:
