Hello all,

I am working with a few IFM devices connected to an edgecontroller (a PLC from IFM).
I have a problem in the second device (or maybe something in the first device is killing the first communication variable of the second one).
The first device A is different than the second one B.
The second device B is giving me several REAL values.
Teh second device B has 17 modbus channels configured. 8 input channels (information I get from sensors) and then 10 output channels (values I can send to the IOLINK device).

When I have to read values, the first device A give me all the needed values, but, when I have to read values from the second device B I can read all the values except the first one it serves (the one on the first channel (input) of the device B).
If I remove the mapping on the first parameter then I can't read the second one, and if I remove the first and the second mappings I can't read the third one, but in all cases I can read the next ones.

Cleaned and rebuilt the project several times.

I've searched for all the crossed references to the variable that is mapped into the first active modbus channel (0) of the second device (B) and I got*:

• Notice the attached image shows the same information but much cleaner.

Is that ioConfig__ErrorPou trying to give me some kind of clue of something that's wrong?

Do you know what does that ioConfig__ErrorPou means?

As always, thank you in advance.
