Scan over existing Configuration
NOTE
Change of the configuration after comparison
With this scan (TwinCAT2.11 or 3.1) only the device properties vendor (manufacturer), device name and
revision are compared at present! A ‘ChangeTo’ or ‘Copy’ should only be carried out with care, taking into
consideration the Beckhoff IO compatibility rule (see above). The device configuration is then replaced by
the revision found; this can affect the supported process data and functions.
If a scan is initiated for an existing configuration, the actual I/O environment may match the configuration
exactly or it may differ. This enables the configuration to be compared.

If differences are detected, they are shown in the correction dialog, so that the user can modify the
configuration as required.

It is advisable to tick the “Extended Information” check box to reveal differences in the revision.
