Bus termination
The end nodes in a ProfiBus-DP network must be fitted with termination resistors, to
prevent reflections in the bus cable.
Bus termination switch
③
is located in the module cover and can
be accessed from outside.
Bus termination switch "ON"
The bus termination is switched on.
If the module is the last or first in the network, this switch must be
set to "ON."
An "external" terminating resistor can also be used in the ProfiBus
connector, however.
Bus termination switch "OFF"
The bus termination is switched off.
When using an external terminating resistor in the ProfiBus
connector, the switch on the module cover must be in position
"OFF."
