Logic Math & Logic Tool - Expression
Expression
The Expression text box is used to construct a logical formula of tool pass and fail results. Use the Job and Tool Data Symbol Tree to assemble the formula. You can enter items by either double-clicking them, or highlighting them and pressing the Insert button.
- If the Expression references a tool that has been deleted, the reference will automatically be replaced by "Job.MissingArg" in the formula. The tool will return a Fail until the reference is corrected.
- When constructing formulas, EasyBuilder does not correctly parse tool names that begin with a cell address (e.g. A3_MyTool or P10_SortTool). If expressions need to be created for those tools, rename the tool before creating the formula.
Job and Tool Data Symbol Tree
The Job and Tool Data Symbol Tree contains the tool pass and fail results output by Location and/or Inspection Tools. The job and tool data are symbolic references to the values contained within them. Symbols can be added to the Expression by one of three methods:
- Expand the tree, select the desired symbolic reference and then press the Insert button.
- Expand the tree, and double-click the desired symbolic reference.
- Using a keyboard, type the name of the desired symbolic reference directly in the text box of the Expression.
Insert Button
The Insert button is used to place symbols into the Expression. Select the desired symbol and then press the Insert button to add the symbol to the Expression.
Open Parenthesis, Comma, Close Parenthesis, AND, OR and NOT Buttons
The Open Parenthesis, Comma, Close Parenthesis, AND, OR and NOT buttons are used to construct formulas. Press the appropriate button to add them to your formula.
Delete Button
The Delete button is used to delete highlighted words or symbols from the Expression. Highlight the desired word or symbol and press Delete.
