To remove an positioner from the PROFIBUS line, its address should
be restored to 126 using this function, so that in future it can be linked
into this or another system if necessary.
If a cyclic master is already in communication with the positioner, the
address cannot be reset.
To prevent unwanted changes made by an acyclic master, the device
can be write protected. To do this, enter the information ”On” in the
write protect submenu for the positioner.
5.2.1.8 Initialization parameters
In this menu the initialization parameters can be displayed, and also
selectively changed. This should however be performed only by
specialists (see chapter 4.7 page 126 ”Optimizing the control data”).
This function is also required if the electronics have to be changed but
at that time no initialization can be undertaken (see chapter 3.7 page
89).
5.2.1.9 Self--calibration
Using SIMATIC PDM, you can also initialize the position controller for
the first time.
This is initiated by going into the ”Device” menu and then into the
”Self--calibration” sub--menu. Press the ”Start calibration” button in the
window that is opened. A warning notice which you absolutely must
adhere to in order to prevent personal or equipment damage will
appear. Note that the self--calibration can also be started from the
acyclic master, even if the position controller is in automatic mode and
contains the set value from a cyclic master.
!
WARNING
Since you are not situated on--site, you must perform the respective
safety procedures before starting the self--calibration to prevent dam-
age to personnel or equipment.
You must also ensure that the self--calibration can only be aborted on
the machine itself by activating the operating mode button or by cutting
off the supply power.
The self--calibration is started after you have confirmed the warning
notice. The progress can be viewed in the SIMATIC PDM window.
After the initialization is complete, the position controller will carry on
working in the operating mode that the self--calibration was started in. If
an error message is generated, the correction must be made on--site.
