All data and control parameters related to the MVI56E-DNPNET are contained in User-

defined Data Types (UDTs). The DNPNETMODULEDEF UDT is the primary, top level data

structure in which all other lower-order data types are grouped and organized. All groups

branch down from this UDT.

To utilize all the features and functions of the module, an instance of each data type is

required. This is accomplished by declaring controller tag variables using these data types in

the Controller Tags Edit Tags dialog box.

Some UDTs hold process or status data (Module Data Objects). This data can be monitored

and manipulated by the application-specific ladder logic program. Other UDTs are used to

store and organize the parameters needed for special functions and control features

(Special Data Objects). These data types will be discussed in more detail in succeeding

topics.
