9 Architecture: The ApplicationTemplate in detail
9.1 Accessing structure variables of machine modules
9.1.1 Accessing module's intrinsic structure variables
The structures of the machine modules contain the input and output variables of the machine
modules for integrating data in the complete system:
• I/O data: Structure MIO
• Parameters / data of the recipe manager: Structure MPar
• Persistent data: Structure MPD
• Visualization data: Structure MVis
The following example shows how a structure variable for an external visualization (assigned to the
MAP) within a module application is to be called (when a module with automatically matching
names is assigned, the matching entries will be added automatically):
[9-1] Extract from the MVIS_scMachine structure
[9-2] Extract from the module application (MAP)
Structures (Structs) for ...
...IOs
...parameters (recipe manager)
...persistent data
...external visualization
// MVis_scMachine
// for MAP1
diPieces : DINT;
// for MAP2
diLength : DINT;
