Convert a program from 2.10.4 to 2.9.4 ?

[Mike Nash]

So I screwed up and made a change to a 2.9.4 BRX using 2.10.4 DmD. I uploaded the program beforehand, but of course I used 2.10.4 to do it. I can't access the PLC using v2.9.4 DmD now that I borrowed just BRX to test NETTIME issue and I wanted to get it back as it was because it was being used on another project.

I tried to export project and import project but the import fails due to the new column in the Element Documentation declaring an invalid nickname. Is there a tickbox I can check to not include this in the export?

Is there any recommendation for converting a project backwards?

Can you restore a backup or did you do a bunch of work in 2.10?  Designer automagically backs up the most recent 4 "saves" (you can change that to UNLIMITED if you have the disk space).

Run Designer 2.9.  File->Manage Projects->Restore from Backup

If you don't have a 2.9 version or you have a bunch of work you need to reclaim, let us know.

I could probably reproduce this by hand if need be. I'm hoping my borrow-wee has a copy of the program. He's been on vacation and now on a job today. I honestly don't know if he used v2.10 DmD and I just realized afterwards the F/W was 2.9. I don't think he had any v2.10 specific instructions.

Regardless, I'm really asking if 2.10 project can be imported into 2.9 DmD successfully. I know the extra column (,"Flags =") in the documentation can be deleted manually from the export file and it imports, but I don't know if the system configuration and devices come in OK.

This may well be flashed to v2.10 anyway, but it's not my call on this one. I do have processors running much older firmware that I am not willing to update because I can't afford to have anything break. I'm occasionally stretching the intended use on some things.

Thanks for offering the assistance though.

Try importing JUST that section into Excel, then remove the bad column, then do Save As CSV and put that back into your export .txt file DOC section.

Ooooh - better

Using 2.10, do File->Export->Element Documentation
and use the default "Standard" (without flags)

Open that file, take that text and copy it on top of the DOC section of your 2.10 export file.

Alright! This looks to work fine. No gripes, and system configuration looks to all import perfectly.

Thanks a bunch!
