CRXXS Codesys 3.5 FB IncEncoder

Dear all,
using FB ifmFastInput.IncEncoder for a couple of fast input, is it necessary to configure, at the beginning of first PLC cycle, the input as frequency input or the Function block do it internally?

I am not sure I follow your question. You will have to call the ifmFastInput.IncEncoder cyclicly if you wish to receive the data from the block. It will handle the configuration of setting the input up as a high speed input.

Right, the execution of FB ifmFastInput.IncEncoder has done cyclic and I get also the results, but I'd like to be sure that the FB handle internally the input setting as high speed input.

It does configure the input properly

Thank you. I was quite sure about it, because the system works simply using the FB but there were some doubts on manual interpretation.
