The Math & Logic feature allows you to program mathematical and logical operations that the OPC server will perform on its data. These operations can range from simple averaging calculations or pass/fail decisions up to complex operations involving algebraic and trigonometric functions, string manipulation, data sorting and Boolean expressions. The OPC server will then provide the results of the calculations to OPC clients just as it would any other data item.
