language support not installed ?

realolman · Jan 19, 2015

I have a RSLogix 5000 program in which I can't search or open a routine called "y-scaling" because it says language support is not installed

I have an analog output that is being transformed from a value in the 40s and 50s to values of 4000+ or so... I suspect it is being accomplished in the y-scaling routine

how do I install language support?

thank you

It's probably done in Function Block because it has a scaling function. Ladder does not. If you don't have the FBD language, you will need to purchase it. The scaling FBD could be made into a AOI and used from ladder. But that would require rewriting the routine slightly.

thank you

I think maybe I'll just assume things are going well in that routine and look for the problem in other places

You could post the program and someone could make a PDF of the routine.

thank you ... that's very kind

You mentioned purchasing the FBD language ... I think I might look into that

Any particular reason someone would have done it that way instead of scaling it with a plain old math block? division ,multiplication or compute??? I think there's even some sorta scaling block that I can't think of off hand

thanks again

There's no magic in the EFD Scaling function. You can definitely do the same thing in ladder with a CPT instruction. A lot of people are use to using the scaling function as the SLC500s had a ladder scaling function.
