Math Library: A math function library is provided for storing User defined equations that may be used frequently.
To save a function, enter the equation in the Math Function text box, then select Save To. A dialog will open allowing for User entry of a short comment about the function to be saved. After entry of the comment, selecting OK saves the function to the User Function Library for future recall.
To retrieve a function for use, select Browse and a dialog will open allowing access to the
Functions can be deleted by highlighting, then clicking on the Remove button.
Units: Provides a text box for User entry of a units label that will be shown at the output from this icon.
Output Name: Specify the label for the Output. This name will show directly under the Output terminal within the Program Net.
Output When: Defines when the Output is updated. If inputs to the icon are updated at different times/rates (asynchronously), the User can specify when the Output should be updated.
X or Y Updated - The Output is updated if either the X or the Y inputs are Updated.
X input Updated - The Output is updated only when the X input is Updated. If a calculation is performed that uses the Y input, the last Y input value will be used in the calculation and the Output will be updated.
1See Example Nets in Appendix B for application ideas on use of the TC Converter functions.
