Detail: Trigger Wildcard is satisfied if the Process Variable is greater than or equal to Lower Value and less than or
equal to Upper Value
Example: [20,40] Trigger Wildcard is satisfied if the Process Variable is greater than or equal to 20 and less than or
equal to 40.
Note: A Trigger Wildcard can combine the usage of parenthesis and brackets.
Example: [20, 40) Trigger Wildcard is satisfied if the Process Variable is greater than or equal to 20 and less than 40.
Single Point Value
Detail: Trigger Wildcard is satisfied if the Process Variable is exactly equal to the single point value. It is not
recommended to use this type of Trigger Wildcard for continuously variable Process Variables . This type of Wildcard
should be used for Boolean Process Variables .
Example: A Trigger Wildcard single point value of 1 is satisfied if a Boolean parameter, such as 9411_1.0 State is
equal to 1 , or TRUE .
Note: For single point value Wildcards, do not use text such as TRUE or FALSE. Use 1 to represent TRUE and 0 to
represent FALSE .
Blank
Detail: If Trigger Wildcard is blank, then the associated operating point is always satisfied. This type of Wildcard can
be useful to specify a default operating point if it is used for operating point 0. If no other Wildcard is satisfied, then
the default operating point will be executed, without setting the Undefined Trigger Error . If another higher operating
point Wildcard is satisfied, then the higher operating point will be executed if the Multiple Trigger Behavior control is
set to “Highest Takes Priority”. Otherwise, the Error OP operating point will be executed.
Flex Control Parameters
Detail: Array of drop-down selection controls for selecting the Flex Control Parameter to be manipulated by each
operating point. There are many Flex Control Parameters to choose from, related to many different controls from
various setup windows within the DI Driver System. The value for each selected Flex Control Parameter will be
overwritten by the value entered for each active operating point in the table. The Flex Control Parameter can be
selected one of two ways: by left unclicking and searching through the full list of Flex Control Parameters, shown
above, or by right unclicking and searching through a hierarchical list of menus to find the particular Flex Control
Parameter of interest, as shown in the Direct Mapping Section .
