Three different types of telegram are available:
1. Configuration telegram: This telegram enables data contents and telegram
length for cyclic data exchange to be specified.
2. Parameterisation telegram: This telegram enables the data contents to be
parameterised (enable bits, decimal places, etc.)
3. Cyclic data exchange: Cyclic exchange of input data (direction: slave

mas­
ter) and output data (direction: master

slave) between master and slave.
The meaning of each individual byte has been predefined in the configura­
tion and parameterisation made before.
