9.15 Multitasking

• The ApplicationTemplate is able to multitask.

• The following tasks are defined in the ApplicationTemplate:

•In the A11_ModuleAppCalls folder, the respective module applications can be assigned to

the corresponding task.

• ModuleAppCalls (MAC) are the calls of a module application (MAP) by the associated

machine modules (MM) of the corresponding task.

[9-27] According to the task configurations, the associated programs (CallFree, CallHigh, and CallMid) are to be called, which, in

turn, call the ModulAppCall programs (MAC_Task_Free, MAC_Task_High, and MAC_Task_Mid).

[9-28] The ModulAppCall program contains machine module applications which are assigned to the corresponding task.

• The connection to the interface system (like for example the I/O system and visualization) is to

be carried out in the corresponding ModulAppCall program (MAC).

• The module applications which are assigned to the corresponding tasks are stored...

• ...in the A70_MachineModuleSources folder or

• ...in the corresponding module libraries.
