218 Part I: Task Manager © Tait Electronics Limited December 2007Defining a Custom Input1. Click New.2. Edit the name that appears in the Custom Input Name column.3. Click in an Input box and select an input from the list.4. If you want the negative of the input to contribute to the custom input’slogic, select the Not check box alongside.5. Repeat steps 3 and 4 for all the standard inputs that will go to make up thecustom input. The Input boxes that you choose will determine the order inwhich the standard inputs are combined.6. Under the Logic heading, select the appropriate options in the drop-downboxes to give the logical combination of inputs that you want. (Forinformation about the effect of the different options, see “Truth Table” onpage 218.)7. Click OK.Truth TableThe truth table below displays the possible individual values for input A andinput B, and the result when you combine those values using each of the sixavailable logic operators. So, for example, if A is true and B is false and wecombine A and B using XOR, the result is true.Working With Custom ActionsThe Custom Actions form (Configure > Task Manager > Custom Actions) letsyou work with custom actions. It displays the list of existing custom actions. Ifyou select a custom action, it displays the set of standard actions that it consistsof. You can also create new custom actions and edit or rename existing ones.A custom action is a user-defined Task Manager action that consists of morethan one standard action. It saves you writing several different tasks with thesame input.A B AND NAND XOR XNOR OR NORfalse false false true false true false truefalse true false true true false true falsetrue false false true true false true falsetrue true true false false true true false
