This System Configuration implements the Model+View+Control testing architecture for the drilling example. It is derived from the DRILL_MVL System configuration by making the following addition and changes:

• The SUPPLY_CTL, LOAD_CTL, DRILL_CTL, and TAKEOFF_CTL Resources are added to the MODEL Device to provide the logic for sequencing and interlocking of operations among the modeled physical elements.
• The *_ACTUATORS Resources of the HMI Device are reconfigured to display the actuator outputs computed in the *_CTL Resources of the MODEL Device.
• An instance of the E_SPLIT FB type is added to the MODEL.CLOCK Resource to ensure proper startup sequencing.
• A RUN/STOP function is added to the HMI.SUPPLY_ACTUATORS and MODEL.SUPPLY_MDL Resources to enable/disable automatic workpiece loading when the SUPPLY conveyor returns to the HOME position. This adds a RUN channel, as shown in the table below, to the Local Multicast channels defined in the DRILL_MVL System configuration.
