Marking of the SIMATIC NET PROFIBUS plastic fiber-optic standard
cable
To help you connect up the cable
correctly, the standard cable has arrow
markings on the orange cord.
This helps to make sure that you attach
one end of a cord to the transmitter and
the other to a receiver (crossed over
cords).
First connect the orange cord:
• If the arrow on the orange cord is
pointing out of the cable, connect this
cord to the receiver. The receiver is
identified by an arrow pointing into a
circle.
• If the arrow on the orange cord points
into the cable (picture), connect this
cord to the transmitter. The transmitter
is identified by an arrow pointing out of
a circle.
The black cord is then connected to the
free socket of the same FO interface.
