Module Data

All data related to the MVI69-101M module 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.

2.3.1 Module Status Data and Variables (MVI69101M_ModuleDef)

All status and variable data related to the MVI69-101M 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
