Exchange more than 1440 bytes with PROFINET Device App

Hello,

I am using the PROFINET Device App on ctrlX CORE. The ctrlX CORE is used as a PROFINET IO Device connected to an external PROFINET IO Controller.

The documentation states a cyclic process data limit of 1440 bytes INPUTS and 1440 bytes OUTPUTS.

Is there any officially supported way to extend this limit (1440/1440 bytes) or handle a larger amount of data with the PROFINET Device App?

I also tried to add a second PROFINET Device instance on another port. It appears in the UI, but the status is “License not available”. Would an additional license allow a second instance to run, or is only one instance supported regardless of licensing?
