NOTE
For the termination of the PROFIBUS DP both termination resistors "PB Term" must be set to
"ON".
PPO-Type
The PPO type used by the bus master is automatically detected by the PROFIBUS DP modules (SK CU4-PBR
und SK TU4-PBR-
…).
Configuration example
A PROFIBUS participant SK TU4-PBR is connected to an SK 200E series frequency inverter via a BUS
connection unit SK T14-TU-BUS. The field bus address (PROFIBUS DP address) is to be "14". The
PROFIBUS DP subscriber is not a final subscriber. The system bus only includes the frequency inverter and
the PROFIBUS DP module. The termination resistor for the system bus is to be set at the frequency inverter.
The DIP switches on the PROFIBUS DP module must be set as follows:
