Deleting devices

An object is deleted from all the SIMATIC PDM configuration views as soon as you delete it
from any of the following views:
● HW Config
● Process device network view and process device plant view

Description
The device is operating in cyclic mode on an AS master or is ready for this mode.
The device is still operating in cyclic mode, however, the AS master rejects all
additional process values. Working information is transferred "in situ" to the
device or by means of a dialog box in SIMATIC PDM.
SIMATIC PDM provides a dialog box where you can set up the device as follows:
● The default sensor values are valid as output variables and are transferred
to the AS master
or
● The actuation information for actuators is specified by SIMATIC PDM. The
reaction is similar to that of "Manual" mode.
The test mode represents an extended type of internal simulation in the actual
device. For sensors, for example, the actual sensor value is manipulated instead
of the output value to the AS master. All calculations generated in auto mode are
executed in the device and the device transfers all of its configured diagnostics
messages to the AS master.
The device goes into the failsafe mode if an error was detected during acquisition
of a process variable.
Devices that have been inserted in a project via HW Config can only be deleted in HW
Config (Edit > Delete menu command).
You can delete devices used once in both process device views. The synchronization
between the process device views is done automatically.
Note
Exception of objects used more than once
Objects that can be used more than once (e.g., a device that can be configured with
redundancy)
● To remove redundancy, delete the partner configured as the slave. If you want to
delete both redundant partners, both objects must be manually deleted.
