[?]: Upload, validation issues plc90-30 Cimplicity ME 5.60

[nickolaym]

PLC374 running and operate properly, thus generally a program in plc is properly too( I suppose).
When i validated the program before uploading, it was successful.
I'm trying to upload logic using CIMLICITY ME from one of our 90-30 PLCs with CPU374. Initially program in ME is ok, but not equal, after uploading it's coming equal with 20-30 errors 8019 and one error 8693 (EGD variable memory area is invalid..)
error 8693 - In ConsPage1 RefAddress is changed from %R02900 to 2900 (in red color).
errors 8019 - In logic blocks some of real type variables are changed.
I corrected errors in editor. Obviously now I must download to plc. But if upload has errors, what can I expect from download?
I would like understand a source of these errors.

What happen during upload? I can't stop plc because a technology is too expensive to stop it. I need exchange one variable (timer's register) because two timers refer same variable and at least one of them don't work. I am afraid to download a corrected version

Any help would be appreciated.

Thanks, Nikolay.
