Reset parameters on the device

Application
Use this menu item to open an online dialog to reset the parameters in the positioner to their
factory settings (default values).
The following parameters can be selected for resetting:
● Initialization parameters
● Device parameters (except 49.PNEUM, 54.STNR and 55.IDENT)
● Parameters of extended diagnostics
● Offline test parameters
The parameters are reset when you press the 'OK' button.
Select 'Device->Load to PG/PC' to transfer the reset parameters of the positioner to SIMATIC
PDM as well.

Reset the field device

Resetting to delivery state
If the positioner has been maladjusted such that it can no longer perform its control task, you
can use the 'Reset' function to restore the delivery state. This function resets all parameters to
their factory settings except for the PROFIBUS address.
Resetting is displayed in the online dialog by the diagnostics message 'Device status' as
"Restart (cold startup) carried out". You must then reset all parameters and execute an
initialization process.
Warm restart
With the warm restart you initiate a complete restart of the positioner. This interrupts and then
reestablishes communication.
This restart is displayed in the online dialog by the diagnostics message 'Device status' as "New
startup (warm startup) carried out". If no measured values are available, the automation or
control system reads in the "Uncertain, initial value, constant value" status.
Resetting the address (STRN) to 126
If no device in your system has the preset address 126, you can add your positioner to the
PROFIBUS path during ongoing operation of the automation or control system. You must
subsequently change the address of the newly connected device to a different value.
If you remove a positioner from the PROFIBUS path, you must reset its address to 126 using
this function 'Resetting the address (STRN) to 126' so that you can re-integrate a positioner in
this or another system depending on the requirement.
The address cannot be reset if a cyclic master is already communicating with the positioner.
