Scaling Problem, help!

[andreik 0]

Good day, I've used scaling countless of times before but up to only +4000. Now, I'll have to scale from +0 to +46900. Is there any scaling instructions to handle this? Thanks, Andrei K.

SCL convert 16 bits unsigned (0 to 65535) to 16 bits BCD

Or use Floating Point

I think you use 12bits BCD unsigned, you need use 16bits unsiged . Edited 10 Jun 2012 by kunshan

One of our moderators, PMCR, helped me with this. Hope it helps Float scaling.cxp Edited 12 Jun 2012 by bluebyu

I like to do this kind of thing using a Structured text Function block. It looks like you have some great working code, here is another way you might do it: Real Conversion and Scale FB.cxp This is not exactly your example, I wrote this a while back as an example for someone else, but it might give you some ideas of other ways to do this in the future. It scales an analog signal (ranging either from 0-4000 or 0-8000) to a range that is entered as an input into the function block. Good luck!
