6. Implement and Test Diagnostic Elements

This system configuration implements the layered Model+View+Control+Diagnostics architecture for the pallet handling example.

The devices in the system encapsulate the functionality of the corresponding layers of the architecture as in the DRILL_MVCDL configuration:

• The MODEL device contains Model, View and user interface (UI) elements as in the LIFTER_MVL configuration.
• The CONTROL device contains Controller and HMI as in the LIFTER_MVCL configuration.
• The DIAGNOSTICS device implements the Diagnostic functions. Diagnostic functions are implemented in the MONITOR resource by instances of the MECH1_DIAGL and MECH2_DIAGL types, and diagnostic messages are logged in the LOG resource by an instance of the DIAG_LOG type.
• Inter-layer communication is implemented with the local multicast pattern.
