Default Signal Values

    Last Modified: September 6, 2017

    You must set the default signal value for every output and variable you configure in the I/O Configuration table. When you use an output or variable in a state machine the default value appears in the Default signal values field on the Module and Diagram tab of the configuration pane for that state machine. The default values will apply when the User Program commences execution. If output values are not defined by the current state, the default value for that output will apply.

    Default signal values appear in a pane in the upper right-hand corner of the state machine diagram.

    You can define default signal values for compound states by editing the Signal values field on the Item tab of the configuration pane. These default values will apply when the User Program transitions into that compound state. If output values are not defined by the current simple state, the default value for that output will apply.

    Default signal values for compound states appear in a pane in the upper right-hand corner of the compound state.
