Profibus Connection
* Termination is required at both ends of the network.
The Profibus master might offer on-board termination.
Make sure that other Profibus slaves with on-board termination are set
up correctly.
Profibus Network Termination The network must be terminated at the first (network master) and the
last PD1 module. A bus cable connector with an internal resistor
network must be used as no internal termination is provied on the
PD1 module. (Refer to Figure 3.7).
