PROFIBUS-DP Termination
The option does not have a termination resistor. The termination resistance must be
set on the final drive in the network using a switch on the 9-pin D-sub connector.
Make sure that only the connector for the final drive in the network has a termination
resistor; communication problems may arise if any other network drive has a
termination resistor.
Use only the input side cable entry as shown in Figure 8 when connecting both
ends of the network. Most 9-pin D-sub connectors have a function for disconnecting
the output side of the cable. Communication will not be possible between devices if
the connector is reversed. Most connectors have arrows indicating the input and
output sides.
