11.3. Information on the supplementary data sheets
In addition to the operating instructions, you will find all item-specific information on the data sheets. This information includes,
along with the modules and submodules installed, information on compatibility (connection type) and on the communication
data that the related module exchanges with the bus module MBM. The following example data sheets show where this
information is given.
