1.6.2 Bus termination with terminating resistors
PLEASE NOTE
A bus termination is required at both ends of the bus
cable.
This also applies if the module or the communication
processor is at the beginning of the bus cable.
Recommendation:
If the CP system is at the end of the fieldbus system, a
bus termination is required.
Use the Sub-D plug from Festo (part no. 18529) for this
purpose. A suitable RC network has already been fitted
into the housing of the Festo-sub-D plug.
The bus termination must be switched manually.
