Similar to the Show Signals option, Show Terminals is another display setting in the Canvas Settings dialog. When this option is enabled, PSCAD will use icons placed on connections and wire termination points to allow for graphical determination of electrical terminal (node) type. In addition, icon colours are used to represent the signal type.
