4.7 Connecting to the Highway and Setting up the
Profibus Card
The Rotork Profibus variants allow for different highway
connections. The ‘single channel’ can be used for simple
highways. The ‘dual channel’ (both Simple and RedCom
compliant) is used for redundant highway applications where
the highway integrity (SR mode) or the physical connection is
important (FR mode).
4.7.1 Single Channel Highway
With the single channel option the actuator is connected
to only one highway. The connection of the actuator to the
highway uses terminals A and B (in and out terminals) and
are indicated on the actuator wiring diagram. The highway
should be arranged so as to eliminate any stub connections.
Take care to ensure that the correct polarity is observed on
the data highway connection, all the A terminals must be
used on one data line and all the B terminals on the other.
• Data line B is positive with respect to data line A when
the PFU is transmitting a ‘1’.
• Data line A is also called TxD/RxD-N
• Data line B is also called TxD/RxD-P
