Parameter Assignment; Introduction To Assigning Parameters - Siemens Simatic CFU Commissioning Manual

5. Use drag-and-drop to move the field device onto the slot (FIELDBUS; FB<n>) to which you
connect the field device.
Observe the following paragraph "Detecting field devices online with the CFU
commissioning wizard".
6. Optional: Assign the CFU PA parameters using SIMATIC PDM (redundant power supply
and extended fieldbus diagnostics).
7. Optional: Assign parameters of the field devices using SIMATIC PDM.
Dependency of configuration of the CFU
The configuration using HW Config takes effect if the "Change configuration" check box is not
selected in the "CFU PA ... Configuration; Commissioning Wizard - Step 5/6" wizard (default
setting):
● The field device is not configured on the CFU PA.
The CFU PA automatically sets the lowest PA profile available for the field device in the
field device.
You can find information on this in section "Manual integration of a field device (Page 83)".
● The field device is configured on the CFU.
The configuration determines the "Selected IO". The CFU PA sets a "Selected IO" in the
field device.
Additional information
● You can find additional information on parameters of the field devices in the documentation
of the field device.
● You can find additional information on using SIMATIC PDM in the SIMATIC PDM help.
