Hello so I have an issue with my HMI simulation. I'm reading Process data from a frequency drive and reading them on an Array of WORD

Offset 4.0 Is the first value I want to show on HMI

As you can see the VDF is showing me the correct values since Offset 4.0 is the OUTPUT FREQUENCY and which is 45 Hz.

I'm choosing the offset 4.0 from my DB from the array

I´m trying to see these values on an HMI simulation but unfortunately I don't see the values on the I/O Field although the PLC reads the value from the VDF correctly. I'm very new on TIA PORTAL and I don´t know if I'm missing something.
