specified logical function each time any of the input points are updated and store the result in the
specified output data point.
Selecting an Output Point
After you select and configure a mathematical or logical operation, you select an output point. The
output point may be any scalar data point or a SNVT_switch data point. You can then configure how
the output point is updated and overridden.
To select an output point, follow these steps:
1. Click the None Defined icon below the Output Point text on the right side of the application.
