Hi all,
After years of programming SLCs i've been pitted against a CompactLogix and a 1769-IF8 analog input card. Ive been playing with configuring the inputs from the card and have come to the conclusion that you can either have it presenting percentage values or engineering/raw values showing the milliamp input values or raw values which arent much use to me either way. Percentage would be good if it were a tank level analog but its a flow meter and I need to scale it to some meaning full range in m/sec.
And so my question. if you do set to use engineering units scaling on the card configuration is there anywhere you can put your own engineering units in to it?
Or
If you can't what do you use (instead of the SCL & SCP commands that were so damn helpfull in the SLC) to convert the analog value to some meaning full engineering value
Im sure it must be me thats being dumb and not the incapable software but any comments either way are gratefully appreciated.
With thanks,
Mike
