7 Fieldbus Interface
7.1 Fieldbus Interface Protocol
The interface works with an 8-byte write window and an 8-byte read window. The fieldbus exchanges its
data cyclically with each slave. This means: In each cycle, 8 bytes are written and 8 bytes are read, also if the
data content is unchanged.
The fieldbus protocol ensures the data transport between the fieldbus master and the 2 x 8-byte data
windows.
The interface protocol runs under the fieldbus and manages the access to a multitude of different data.
