Proceed as follows to initialize the positioner using SIMATIC PDM for the first time:
1.
For this purpose, go to the "Device" menu and then to the "Initialization" sub-menu. A
window containing an overview of initialization-relevant device parameters, checkback,
device status, diagnostics and initialization status then opens.
2.
Press the "Start initialization" button. A warning is then displayed. Follow this warning
without fail to prevent personal injuries and damage to the system.
3.
Acknowledge the warning.
The initialization process starts once you acknowledge the warning. You can monitor the
progress in the "Status (initialization)" field in the open window of the initialization menu. As
soon as the initialization is completed successfully, the positioner continues working in the
operating mode from which the initialization process was started. If a fault message appears,
an on-site correction is required.
11.2.2.13
Reset PDM parameters
Use
Use this menu item to open a dialog box to reset all PDM parameters to their factory settings
(default values).
PDM parameters are reset when you press the "OK" button. You can then transfer the
parameters to the PDM memory using "File->Save".
Select "Device->Load into devices" to transfer the reset parameters to the positioner as well.
11.2.2.14
Reset the field device
Reset the positioner to the as-delivered condition
If the positioner has been moved such that it can no longer perform its control task, you can
use the "Reset" function to restore the as-delivered condition. This function resets all
parameters to their factory settings except for the PROFIBUS address.
The reset action is indicated by the "Restart executed" diagnostics message. You must then
reset all parameters and execute the initialization process.
Warm restart
Use the warm restart to exit the positioner, shut it down and restart. The communication is
interrupted and restored while doing so.
This warm restart is indicated by the "Warm restart executed" diagnostics message. If no
measured value result is available, the automation or control system reads in the
"Uncertain, initial value, constant value" status.
Reset the PROFIBUS address to 126
If no device in your system has the preset address 126, you can add your positioner to the
PROFIBUS path during the ongoing operation of the automation or control system. You must
then change the address of the newly integrated device to another value.
