### 8.3.2. Checking connections

Before invoking calculations and the thorough data diagnostics associated with that, it is advisable to check the connections. This consists in making sure that there are no unconnected components. If there are connection errors in the system, they will be indicated in the diagnostics results window displayed after invoking calculations, so it is more convenient to make the necessary corrections before invoking calculations.

¨ To start connection checking select “Component data / Check connections” (Shift+F2).

A window is opened with a list of messages on connection errors found in the system:

The structure of this window, types of messages that appear there and the manner of finding components associated with the errors are identical to that of the diagnostics window and are described below. If the system is completely correct, the window is empty.

Data editing is not possible when the connection diagnostics window is displayed – you have to close it by clicking on the “OK” button. Information on erors is not lost – it will be displayed in the error list of the graphical editor.
