Hello @m_tomiyoka,

Welcome to the forum!
This could be a problem with the tag’s address.
Try to do the following:

  1. In Factory I/O set input offset to 10 and output offset to 0.
  2. In Tia portal use addresses for inputs starting at I10.0 and outputs from Q0.0

Let me know if this helps or if the issue persists.
