2.1. Comparison in Offline mode only

Unity DIF will compare project files from the same PC or from remote PC. In this mode, it’s not possible to compare a project file directly with a project embedded into a PLC

2.2. Use of Security Editor

o If the Security is ON in UnityPro or EcoStruxure Control Expert, Unity DIF will compare project files after asking for the appropriate profile to be used. However, for Unity DIF to function correctly, the profile should have rights to at least do the following: Open an existing project, Import and Save project. In case of default UnityPro or EcoStruxure Control Expert profile, it is recommended to use the PROGRAM profile.

o If the Security is ON in UnityPro or EcoStruxure Control Expert, the samples cannot be used directly. Need to modify them to provide the username and password of the correct profile to be used for the comparison and recompile the samples.

o If the Security is ON in UnityPro or EcoStruxure Control Expert with no login or avoidable login, Unity DIF will still prompt for the username and password. Provide the username and password of the correct profile to be used for the comparison

2.3. Project Settings Limitation

Since few Project Settings have been changed from UnityPro or EcoStruxure Control Expert 14.0 onwards, the comparison of project files of earlier versions may contains added or deleted differences in the Project Settings section.

During project Import / Export in UnityPro or EcoStruxure Control Expert, it could happen that whitespaces at the beginning or at the end of certain language elements are being removed which leads to insignificant differences displayed in Unity DIF.
