MVI56E-61850S Controller Tags ...........................................................49
Although the MVI56E-61850S configuration is done in PCB, it is maintained in the
MVI56E61850S controller tags of RSLogix 5000. This chapter covers the tag structure and
locations of the MVI56E-61850S parameters in RSLogix 5000.
4.1
MVI56E-61850S User-Defined Data Types
The sample ladder logic relies heavily on the use of User-Defined Data Types (UDTs) to
help group and structure the wide variety and volume of data and control features the
module offers. Lower-order UDT structures are often embedded in higher-order structures to
help further organize data into more easily understood data collections.
All data and control parameters related to the MVI56E-61850S are contained in User-
defined Data Types (UDTs). The MVI56E61850S_MODULEDEF 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.
