Posted 7 Feb 2022 (edited) I have a piece of machinery that has multiple PNOZ m1p units that communicate to each other. My trouble is that the base units versions vary from 5.6 to 6.5 and we found a programmed SD in the older base versions will not run properly in the later base units. We don't have the software and frankly, taking on the liability of the machines safety if we reimage the chip to newer software (which we also don't have) is not in our best interest. The company that created the system may not service the system anymore thus rendering the 3/4 million dollar machine down to scrap metal. Anyone know where I can get a base version list which os sd cards are compatible (ex..but not exact...for reference only...V5.6 to V6.2 will work, but upgrade required at V6.5 base)? From this we can add up the upgrades and propose full replacements. It was a great idea, but can be crippling with the way technology changes.

Posted 7 Feb 2022 To a certain extent, the end-user is liable anyways, at least in the U.S. (IANAL, but that's my understanding.) I'd get the software. Share this post Link to post Share on other sites
