3.1.4 Application Data Tag Structure
The Application Data structure is a Control Module-Scope structure that
contains the application data (Teach Points, Tools, IZs, etc…) for a given
project. The MLX200 HMI (described in Section 3-4 “MLX200 Tag
Structures” on page 3-5) will automatically link to this structure when you
Teach Points or enter Tool/UF/IZ Data from the HMI. The overall data
structure is shown in Fig.3-4 "Application Data Tag Structure".
Fig. 3-4: Application Data Tag Structure
The Application Data structure is designed to be configured so that a user
can extend or contract the amount of data stored in it based on the
application needs and available Control Module Memory. To change the
size of the Application Data requires two steps:
1. Change the variable corresponding to the type of data.
2. Change the array size of the UDT corresponding to the type of data
For example, Fig. 3-5 "Changing the Size of the
ApplicationData.NumberOfJobs Variable" on page 3-6 and Fig. 3-6
"Changing Size of the MLxAppDataJob UDT" on page 3-6 show changing
the number of Jobs from the default value of 10 to 20.
Failure to match the length of the arrays with their corresponding size
variable can allow an out-of-index array which will cause the Control
Module to fault.
