Motion! Servo Drives, Motors, Actuators, & VFDs by Unitronics

Merle, the point Gabriel is making is that hardware scaling is essentially fixed and can't be adjusted easily.  Ladder versions can. JR, side question....Are you sure that you haven't got mixups in various settings, so that 4-20ma and other mistmatches are happening? FYI.....Although this was made for Visilogic, perhaps it might be useful for your "play" and diagnostic purposes.  I'm sure the fundamentals are similar.  The whole point for me making it in the first place relates to Gabriel's similar use, where minor tweaking of some numbers in use gets things exactly right.  Online interaction and adjustment can then be done.  In my case in Visilogic, after tweaking I change values to permanent. https://forum.unitronics.com/topic/3540-linearization-calculator-for-all/ cheers, Aus

Did you format the SD card using the recommended software before creating the image? I followed the procedure some time ago and had to use a different software to format the SD (I might be wrong and had to use it for another purpose or another PLC brand). Anyway, here is the software I have: https://www.sdcard.org/downloads/formatter/

The next step is to write messages from a vacuum cleaner or a kettle.

I did some more digging and it looks like there is an issue with the unitronics recovery .img file. I've tried to write the SD card on several PCs at this point and the win32diskimagger will just crash once I click Write. Also the few times it successfully wrote the image to the SD card it displayed no data on the thumb drive. Does anyone know if there's a mirror for the factory reset links?

That's irrelevant.  They still have to be linearized differently for different bit count.  14 bit input has to be linearized over 16383 range and the 12 bit out has to be linearized over 4095 to use full voltage range.
