Solved !!
I hve onlychanged analogRead with digitalRead

Thanks for advice.

Hi Comingback4u,
You've caught the problem !!
If I put to 1 input A0 I also activate bit 1
If I put to 1 A1 and I put to 0 A0 I activates bit 1 and bit 2 and so on.

In the picture I put A0 to 1 !!

How can I solve on Arduino code?

Thank you, Alberto

Don't know anything about this but I'll take a guess:
Any chance it has to do with passing an INT value int a bit when you do bitWrite( au16data[0], 0, analogRead(CONTROLLINO_A0));

Good evening,
I use this code to control modbus control
I use the digital outputs to control 6 on-board relays and analog inputs to check the status of relay relay-controlled relays to know their status.
I do not understand why when I pass an analog input into codesys i go high two inputs at a time.

I do not know if I made the problem clear but in case you could give me a hand?

Thank you, Alberto
