Assigning parameters to CFU online via SIMATIC PDM

This section is only applicable to a CFU PA.
Startup phase of a field device
The power supply of the field devices is enabled in the default parameter assignment of the
CFU PA. You can disable individual fieldbus connections in the parameter assignment of the
CFU PA in the "CFU PA ... Configuration; Commissioning Wizard" dialog of SIMATIC PDM.
● During the startup phase of the field device, the green LED flashes.
● When the startup phase is successfully completed, the green LED is continuously lit.
You can find additional information on this in section "Startup of field devices depending on
the configuration (Page 52)".
Communication with the field device is then possible via SIMATIC PDM.
If the commissioning of the field device fails, communication with the PROFIBUS PA field
device cannot be established.
● You can find information for analysis of the cause in section "Diagnostics via LED
displays (Page 91)".
● If the field device is configured using HW Config, a diagnostic interrupt is generated.
Communication between a field device and the CFU PA
Following connection of a field device, the CFU PA automatically attempts to set the
PROFIBUS PA address on the field device.
You can find the assignment of fieldbus connections to the addresses of the PROFINET PA
field devices in section "PROFIBUS addresses of the PROFIBUS PA field devices on the CFU
PA (FBn) (Page 151)".
The supported profiles of the PROFIBUS PA field device are read out and made available for
selection in the commissioning wizard.
You can find information on this in section "Startup of field devices depending on the
configuration (Page 52)".
