2.4.11.2 Evaluate
Here you can evaluate a logical expression, which can contain variables and system functions, in addition to numeric values and strings. Call handling will then branch based on the result.
The action is terminated,
*if the analysis of the defined output results in the logical value "True", or
*if the analysis of the defined output results in the logical value "False", or
*if the call was disconnected.
Under "Properties", all three tabs "General", "Parameters" and "Connections" tabs are available for this block.
This is how you define the parameters for “Evaluate”
1 Enter a logical expression to be evaluated here.
Here you can also select and add other available variables and system functions from the list of variables .
2 Click on "OK" to close the window.
The “Evaluate” block can be seen on the grid interface and it is available for further processing.
Links
On this tab you will find all outputs associated with this block. The outputs are described as follows:
Output
Explanation
True
This exit is chosen if the evaluation of the defined output results in the logical value “True”.
False
This exit is chosen if the evaluation of the defined output results in the logical value “False”.
Disconnected
This exit is selected, if the call is disconnected.
In the first column "Visible", you can define whether each output should be shown in the script window.
* 
The "Visible" column is only used to define the visibility of the links in the script window. This setting helps to maintain the clarity of the script. You cannot remove outputs, i.e. the connections must be kept, otherwise an error will occur in the script.
 
The second column "Default" contains the default name of the output. This provides information about events during the execution of a block so that additional appropriate connections can be created. This fixed name cannot be changed. You can assign your own identifying names to the various contact surfaces in the column "Link name". This name will later appear in the block in the grid interface.
In the last column "Linked to" you see which block input this output is connected to. Here you have the option of selecting a link from a select list, which contains all available blocks.
