The "Reconfigure" function allows for the dynamic adaptation of a PROFINET configuration, which was initially downloaded to the controller, to the application at runtime.
With the function block DED.Reconfigure, which is available when the generic device diagnosis is enabled (“PLC Settings:”), any device configuration in the device tree can be enabled or disabled.
In the case of PROFINET, this function block can be executed on the following devices:
-
PROFINET Controller
-
Individual slave nodes of a controller configuration (not CIFX)
-
PROFINET Device
When disabled, different configuration parameters of the devices can be changed:
-
Station name
-
IP addresses
-
Slot and subslot numbers of the modules or submodules
-
Device settings (manufacturer-specific data records)
Then these settings are used when the device is enabled again or for the reestablished connection.
