Properties Expander

In the Models & Functions tab, the Properties expander lists all the properties of the selected object model or function. Here you can perform various configurations including:

View the alarm definition settings
Define how properties are logged
Set visibility of properties and how they are displayed
Define backup settings within the system

A number of check boxes and selection lists let you view or define various settings for each property. In addition, expanders on the right provide further configurations for the property selected in the list. The specific configurations available vary depending on whether you have selected an object model or a function.

Item	Description
Property	List of all available properties for the selected object model or function. Drag-and-drop to adjust the sequence of the individual properties. Viewer display (Status and Commands window) follows the sequence defined in this list. A data type of an existing Object Model is highlighted in red in the Property expander if it is not changed using the Model & Function editor. Save the Object Model to refresh the instances using the default value of the newly selected data type.
FS	Read-only check box. Indicates whether the property has a Field System (FS) alarm configured. A Field System alarm is an event generated by a supported control unit or field device where the driver is in charge of generating this kind of alarm, generally based on specific alarm tables.
MS	Read-only check box. Indicates whether the property has a Management Station (MS) alarm configured in the Alarm Configuration expander for this property.
VL	The property is logged in the Value Log (VL) of the History Database. The Value Log is the database that collects any information relevant to value changes for trending (for example, temperature value for an Analog Input Temperature Sensor). Select this check box only if you want to enable value logging for all objects based on this object model Do not enable logging for all properties in general, as this can result in a large amount of data depending on the project size or data frequency
AL	The property is logged in the Activity Log (AL) of the History Database. The Activity Log is the database that collects any information relevant to the operators' activity or system activity (for example, alarm handling, acknowledged alarms, and so on).
DL0	(object models only ) The property is visible in configuration expanders (System Manager in Engineering mode).
DL1	The property is visible in the Status and Commands window available for graphic objects.
DL2	The property is visible in the Operation tab.
DL3	(object models only ) The property is visible in the Extended Operation tab.
DL4	(object models only ) The property is exposed to the OPC server interface and other northbound interfaces in future that will make use of this setting.
Stat	Select this check-box to enable off-normal status configuration for this property in the Details expander.
Persist	(Object Models only ) If set, the value of the property is saved in case Desigo CC is stopped and restarted. This option is set for the configuration of properties that must be already have a value assigned at system start-up (for example, the IP address of a control unit to connect).
Property Group	Used to assign a property to a specific group for which you can configure different access levels and visibility in the Security configuration.
Add	(Functions only) Adds a new property to the function
Remove	(Functions only) Deletes the selected property from the function
