I would like to ask why the input terminal (in) for this command is red. I have defined it in the symbol table as AI01 equal to PIW2, so why is it still red?

It’s probably because the data type you defined is incorrect. Send me a screenshot of your symbol table so I can take a look

The images you upload cannot be seen; it is recommended to take screenshots and save them as JPG files, as they are smaller in size.

@budaowen123, please take a look

I’ve replied; take a look. I’m replying directly – you can’t add pictures. Go downstairs and take a look.

It seems that the AI signal addresses PIW all start from PIW2XX by default. Did you assign PIW2 yourself? Add me on QQ: 35480934
