I would like you please to support me. I have one analogue number which I need it to turn on to red when it is exceeding the value 1.8 m/s, and remain @ green for less than 1.8 m/s. Please see the attached picture. I have AC450 PLC. I tried this code but it is not accepting:
if FsF6SpdAct > 1.8 then
It is giving symmetric error. Is there any additional things I need to do ?
Also I would make a custom color definitions with named colors like TypicalAlarm TypicalNormal, if you later on you need to change the color, you can do that in the color definition. You than have a defined set of colors for everyone to use when engineering graphics.
