Device description dependency
When a device is replaced in a plant, you have to update the project in SIMATIC PDM. When
devices are replaced in a plant, the following situations can arise:
● Device descriptions are compatible
The device to be replaced can be operated with the device description of the device to be
integrated (e.g. after updating the firmware).
The configuration can be downloaded to the device to be integrated.
● Device descriptions are incompatible
The device to be replaced cannot be operated with the device description of the device to
be integrated, e.g. a device is replaced with one from a different manufacturer.
The device to be replaced should be removed from the configuration when it is replaced
with an incompatible device. Reconfigure the device.
Recommendation:
Export the device data before making the change, because the device will be initialized
again with the new device description.
The following steps describe how to reassign the device description.
Assigning a device description to an object
You have the following options for assigning a device description to an object:
● Identify a device via an online connection
● Assigning the device description manually
Identify a device via an online connection
If you have an online connection to the device, click the "Device identification" button.
● "Device identification" button
When you click this button, a connection to the device is established and an attempt is
made to read the information from the device and assign the required device description
to it.
● If not all the necessary information could be read out, you need to assign the device
description manually. After device identification
you can only see the structures required for the device in the tree structure.
Make your selection from these structures.
Assigning the device description manually
Select the required device description from the "Device catalog" list, based on the following
data:
● Device type
● Manufacturer
