PROFIBUS PA
The digital communication signal is transmitted to the bus via a 2-wire connection. The bus also provides the
auxiliary energy. 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 BA034S
"Guidelines for planning and commissioning PROFIBUS DP/PA" and the PNO Guideline.
Cable specifications:
• Use a twisted, shielded two-wire cable, preferably cable type A
Note!
For further information on the cable specifications, see Operating Instructions BA034S
