Pin configuration and wiring of PROFIBUS-DP
The two data wires for PROFIBUS are also called A and B. There is
no rule which data wire color must be connected to which pin but it
must be done consistently within the whole system (over several
slaves and segments).
If a transmission cable with red and green data wires is used the
cables should be wired as follows:
Data wire A - Green
Data wire B - Red
The names are the same for incoming and off-going data wires.
PROFIBUS interface connectors
We recommend to use ERbic® PROFIBUS interface connectors from
ERNI. The interface connectors can be used for the BC and EC bus
couplers.
