PROFIBUS PA
The digital communication signal is transmitted over the bus via a 2-wire connection. The bus also
provides the power supply. For further information on the network structure and grounding, and for
further bus system components such as bus cables, see the relevant documentation, e.g. Operating
Instructions BA00034S "PROFIBUS DP/PA: Guidelines for planning and commissioning" and the PNO
Guideline.
