Does OS Update Delete Ladder Programme?

Recommended Posts

I have an old Jazz JZ10 that requires a programme change.

The U90 Operating System settings tell me I require an update but I don't have an offline copy of the programme and want to ensure it doesn't get erased...

Don't do anything yet.  The best solution is to simply use the version of U90 that doesn't want to update the OS.  But I don't have the knowledge as to what version that is.  Someone else is  sure to know. 

Once you have that successfully in place, you should try to get the program out of the plc.

cheers, Aus

No-one has chimed in yet, so you have a choice.

1).  In theory the program is totally unaffected by the OS update and you can do it ok.

2).  Contact support@unitronics.com, ask them the question and they should know and give you a link to the correct U90 version.

I'd be inclined to wait the little bit longer and do no. 2.  If something does go astray for some reason during the update, you're covered.

cheers, Aus

I'll chime in: Listen to Ausman - he is speaking wisdom.

Good advice.

I did #2 and Unitronics gave me a link to the matching software version.

And it worked.

Thanks again for your help.

In general is should not remove the application. (unless it is a really really old OS).

Anyway it is required always to load the application from the U90Ladder that is compatible with the OS. 

In this case upload the program , update the OS and load the application again.
