Configuration steps
The following items must be configured in the planning of an SK CU4- … or SK TU4-PBR(-M12) technology
unit:

PROFIBUS address Setting the PROFIBUS DP with DIP switches (Section 2.2.3
"Configuration
")

Integration of the DP slave (technology
unit) on the PROFIBUS DP
Select the components from the catalogue and integrate
them into the PROFIBUS DP string.

The frequency inverters connected to
the technology unit must be defined
Specification of the frequency inverter designation and
allocation of the associated addresses / slot allocation.

Configuration of the DP slave Assign the names and addresses

Selection of PPO types Each frequency inverter must be assigned a PPO type
(parameterise on the appropriate slot)

Technology unit I/Os For the use of additional technology unit I/Os, the Profibus
module I/O must be integrated into Slot 1 of the DP slave
4.2.1 DP slave slot assignment
The following slot assignments must be observed in the DP slave for the planning of frequency inverters:
Cyclic data traffic
The assignment of the input and output address ranges to the frequency inverters is made via the assignment
of the slot position.
Slot Cyclic process data
transfer
Device
1 Profibus I/O Modules Technology unit I/Os
2 PPO type 1 to 4 Frequency inverter 1
3 PPO type 1 to 4 Frequency inverter 2
4 PPO type 1 to 4 Frequency inverter 3
5 PPO type 1 to 4 Frequency inverter 4
Acyclic data traffic
The assignment of acyclic data packages to the individual frequency inverters and the technology unit is not
carried out via the slot position, but rather via Slot 0 and the relevant index (Table):
Index Acyclic parameter
transfer
Device
100 only parameter data Technology unit
101 only parameter data Frequency inverter 1
102 only parameter data Frequency inverter 2
103 only parameter data Frequency inverter 3
104 only parameter data Frequency inverter 4
Therefore no settings and configurations are required in the Hardware config. of the SIMATIC Manager are
necessary for the use of acyclic data traffic for the transfer of parameter data.
