Error downloading application to new V350 over serial and ethernet

[Fre_ZZe]

Hi,

I'm having trouble downloading my application to a new and clean V350-35-R34, it fails over both serial and ethernet.

Loading Bin. Lib, Boot, OS and Sync RTC works fine.

My UDC file contains the following, and I'm trying to execute using UniDownloader v. 4.1.02:

Bin.Lib v. 2.1 (02)

BOOT v. 2.1 (06)

OS v. 3.0 (67)

Sync. RTC

Application

As said, I'm able to download Bin.Lib, Boot and OS. I then do Sync RTC fine, but when trying to only execute the application item to the PLC it says Application failed.

This happens during: Status: Downloading String Lib to PLC. The UDC file is 628kb big.

This is creating big problems for me at the moment, as I need to be able to distribute this UDC with the new application to a lot of customers..on both old and new PLC's (upgrade/reinstall of application)

Any ideas?
