Hi all,
I am working with a PLC S7-300 CPU 315-2DP
I programmed an OB32 for sending data over an ethernet, but when I try to download it to the PLC I get this message:

(D20C) OB cannot be copied as the associated
priority class does not exist.
Unable to copy the block OB32

It is the first interruption I have ever programmed, so I don't know the reason for the error.
I just copied the OB32 from the Standard library and programmed what I wanted it to do,Have I missed something?

Greetings and Thank you in advance,
Ana
