Allows configuring which tabs are visible on a PowerExplorer window. If this window is already open, these tabs are immediately updated. This property accepts a combination of values 1: Displays only the Analog tab, 2: Displays only the Discrete tab, 4: Displays only the Command tab, or 8: Displays only the Protection tab. For example, the value 3 (three) displays Analog and Discrete tabs and hides Command and Protection tabs. The value 12 displays Command and Protection tabs and hides Analog and Discrete tabs. The special value -1 (minus one, default) always displays all tabs. The value 0 (zero) is not accepted, that is, users cannot hide all tabs, which generates a script error.
