5. Develop and Test Controllers

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

• The HMI,MODEL and VIEW devices encapsulate the functionality of the corresponding layers of the architecture.
• As in the DRILL_VIEWL configuration, the VIEW device contains two instances of the specialized VIEW_PANEL resource type to provide the necessary layout of View elements for the drilling example.
• As in the DRILL_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 elements, including the logic for sequencing and interlocking of operations among the modeled physical elements. Control is achieved through instances of the function block types XBAR_CTL, LOAD_CTL, XSLIDE_CTL and MACH_CTL.
• Inter-layer communication is implemented with the local multicast pattern.
