2.1.3 Module Data Object (PNPModuleDef)

All data related to the MVI56-PNPM is stored in a user defined data type. An
instance of the data type is required before the module can be used. This is done
by declaring a variable of the data type in the Controller Tags Edit Tags dialog
box. The structure of the object is displayed in the following figure.
This object contains objects that define the configuration, user data, status and
command control data related to the module. Each of these object types is
discussed in the following topics of the document.
Configuration Objects
Configuration of the module is performed by filling in the values in the module
object defined in the Controller Tags Edit Tags dialog. Each parameter required
by the module has a defined location in the object. The following tables and
topics describe the parameters set in the dialog box. You can view these tables
by opening the data type under the User Defined Data Type option in the
Controller Organization window.
