A measurement file object (ElmFile) is used for this purpose. Attached you can find a small example which displays the first 3 channels of a ComTrade file. A measurement file object (ElmFile) is located within the "Grid" network. This measurement file object must be linked with the external file by setting the correct path in its Edit Dialogue.

By executing the dynamic simulation, the values of the ComTrade file channels are displayed in PowerFactory.
