5. Develop and Test Controllers

This system configuration implements the layered Model+View+Control testing architecture for the assembly example.

• The MODEL and CONTROL devices encapsulate combined architectural functions in the same manner as in the DRILL_MVCDL example.
• As in the ASM_VIEWL configuration, the VIEW device contains one instance of the specialized VIEW_PANEL resource type to provide the necessary layout of View elements for the drilling example.
• As in the ASM_MVL configuration, the MODEL device contains the Model elements and the logic for their interactions, including the transfer of workpieces among the modeled physical elements.
• The CONTROL device contains the Controller and HMI elements, including the logic for sequencing and interlocking of operations among the modeled physical elements as well as a RUN/STOP switch for starting and stopping the assembly sequence. Control is achieved through an instance of the function block type ASM_CTL.
• Inter-layer communication is implemented with the local multicast pattern.
