Action: CompareVariableList

Function: The action atomically compares an entire list of values in the same monitoring cycle.

Call: Monitoring test driver

Tab: Configuration

Timeout (ms)	Time span in which the test has to be successful The test is repeated during this time. If a value is not defined, then reading is done one time only without delay.
	You can define any number of comparisons in the list by manual entry. You delete the selected line by means of the Delete command. The entry is not checked (variable type, value range).
Variable	Fully qualified name of the variable instance to be checked When a project is loaded, the Input Assistant is available to help with this (auto-completion or intelligent coding).
Compare type	Comparison operator to check against
Value/ From value	Value to compare with From value describes the starting value for compare type Range. The values have to correspond to IEC syntax.
To value	End value for compare type Range

Tab: Parameters

The parameters defined on the Parameters tab are used to exchange values between test script variables and parameters of test actions. Parameters can be used as placeholders on the Configuration tab. For this, the name of the parameter is set in braces in the configuration dialog. Example: {name}.

Tip

Variables defined globally in the script (with the prefix $GLOBALS.) can be used directly in the test action. It is not necessary to use input parameters for passing. Using output parameters is necessary for writing global variables.

Input parameters: When executing the test action, the values of the test script variables are passed to the input parameters of the test action and can be used in the configuration of the test action.
Output parameters: When executing the test action, the values of the output parameters of the test action are passed to the test script variables and can be used (for example, in other test actions).
Name	Name of the input/output parameter This name is defined in addition to the variable name to identify the origin of the parameter when it is passed to another script. During the test run, this name is displayed as the Outer name on the Variables (scope #<n>) tab in the Test progress window. Background: When a script `A` calls another script `B`, and its variable `x` passes `y` as a parameter to the script `B`, then the parameter `y` is the variable `y` from the point of view of script `B`. To see that this variable is recognized as variable `x` "outside" of script `B`, there is the Name column ("Outer name"). The variable `y` has the name `x` in the scope pf script `B` because it has been passed as variable `x` to the parameter `y` in the scope of the calling script `A`.
Variable	Name of the test script variable Example: `TS_CaseA_Result`
Move Up	Moves the selected variable one line up
Move Down	Moves the selected variable one line down
Remove	Removes the selected variable from the list
