Hi all,
I am new to PLC programming and so far I am able to work with on/off logic quite well. But I am having problem in scaling PLC analog output. I am supposed to write to analog output the value of temperature (0-130 degrees in engineering units). I know that I need to scale engineering units to raw values.
engineering units(0-130) to raw values (0-27648) to analog output (0-10V).
Is the way of scaling analog outputs correct? Do I need to convert from raw values (0-27648) to analog output volts (0-10v) or PLC (ABB AC500) does it automatically?
Looking forward for help.
Regards
