5. Save and compile the project.
6. Download the project data to the S7-CPU.
You have inserted your project into the inverter and loaded your configuration to the CPU.
Permitted sequence for the slot assignment
1. PROFIsafe telegram, if one is being used.
Information on connecting the inverter via PROFIsafe can be found in the "Safety
Integrated Function Manual".
2. PKW channel, if one is used.
3. Standard, SIEMENS or free telegram, if one is used.
4. Direct data exchange
If you do not use one or several of the telegrams 1, 2 or 3, configure your telegrams starting
with the 1st slot.
Cyclic communication to the inverter when using the universal module
A universal module with the following properties is not permitted:
● PZD length 4/4 words
● Consistency over the complete length
With these properties, the universal module has the same DP identifier (4AX) as the "PKW
channel 4 words". The higher-level control does not establish cyclic communication with the
inverter.
Workaround when using the universal module above:
● In the properties of the DP slave, change the PZD length to 8/8 bytes
● Change the consistency to "Unit".
