6. Delete the SITRANS LR250 in HW Config. This deletion of the device type is required
because the LR250 and LR260 have different GSD files. The associated PDM object is
automatically deleted with it.
7. Configure the new device type (here an LR260) in HW Config using the backed up
property information (e.g. settings, addresses).
8. Perform the assignment of parameters of the LR260 in the PDM. In so doing, take note of
the procedure for the configuration and parameter assignment of field devices described
in "PCS 7 Compendium – Part A" (www.siemens.com/pcs7-documentation). You can also
find further information in the section titled "Changing the AS configuration" (Page 72).

Case 3 – Removing field devices
Before removing a field device, the entire parameter assignment should be exported.
To back up the parameter set of a PDM object, switch to the process device plant view of the
SIMATIC Manager. Select the device and select "SIMATIC PDM > Export ..." in the shortcut
menu.
Note
As long as a PDM object is in the PDM database, one PDM tag of the associated license is
used. Devices which are no longer used and which have been backed up must be deleted to
release these PDM tags.
Procedure in PDM V9.1
1. Switch to HW Config and remove the field device (HART, PA, FF, DP).
Further steps are not necessary, because the associated PDM object is automatically
deleted in the process device plant view.
You should therefore take note of the recommended procedure for backing up device
parameters which is described in the section "Scenario 2 – Replacing a device with a
different type" (Page 68).
