By default, every change in the value in an event-driven PDO causes a telegram to be sent. The interrupt
mask makes it possible to determine which data changes are evaluated for this purpose. By clearing the
appropriate ranges within the PDOs they are masked out for event-driving purposes (interrupt control). The
interrupt mask does not just govern all the PDOs with digital inputs, but all the TxPDOs that are present. If
the TxPDOs are shorter than 8 bytes, then the superfluous part of the IR mask is not evaluated.
The interrupt mask only has an effect on TxPDOs with transmission types 254 and 255. It is not stored in the
device (not even through object 0x1010). Changes to the mask at runtime (when the status is operational)
are possible, and are evaluated starting from the next change of input data.
The interrupt mask for TxPDOs with analog input data is not evaluated if either limit values (0x6424, 0x6425)
or the delta function (0x6426) have been activated for the inputs.
This entry has been implemented in firmware C3 and above.
