This object contains attributes common to many Metasys system objects. These common attributes are described in the Common Object Attributes section. This section includes attributes of the Focus/Configuration tab, the Diagnostics tab (if applicable), and any other tab specific only to this object. See the Object and Feature Tabs section for information on the attributes that appear on the other tabs of this object (for example, the Hardware and Options tab appear on point objects). The writable attributes in the N2 Master Datalink object are writable only if the UDP Port attribute is not zero. If the UDP Port attribute is zero and you attempt to write these attributes, an error message appears.
