|Basis for reference projects|
In addition to the current project, you have the option of opening other projects or local sessions as references. These reference projects can be used as follows:
- You can drag individual objects from the reference project into the current project and then edit them.
- You can open specific objects, for example blocks of code from a reference project, as read-only. However, this is not possible for all elements.
- You can use offline/offline comparison to compare the devices of the reference project with those of the current project.
Please note that reference projects are read-only. Reference project objects cannot be changed. Therefore, pending changes, such as object name changes, cannot be applied to the reference object until the project is opened as a normal project. Once the changes have been applied, you can continue to use the project as a reference project.
Projects created with an older version of TIA Portal or from another installation package can also be opened as reference projects. The same compatibility rules apply here as when normally opening a project from an older version of TIA Portal. Project archives can also be opened as reference projects.
|Opening and closing the reference project|
You can open projects and locally saved sessions as reference projects.
Opening the reference project
To open the reference project, follow these steps:
Closure of the reference project
To close the reference project, follow these steps:
|Comparison of reference projects|
Devices from reference projects can be compared both with devices from the current project and from the same or another reference project or library.
Please note the following:
To compare the objects of the reference project with the device data in the current project, perform the following steps:
