Use the ACTUATORS to exercise the Model and View elements.
Click on a View element to simulate a fault. Click again
to clear the fault condition.
- The HMI devices encapsulates the functionality
of the corresponding layer of the architecture, while the PNP
device encapsulates the functionality of the Model and View
layers.
- As in the PNP_VIEWL
configuration, the PNP device contains an instance of
the specialized VIEW_PANEL
resource type to provide the necessary layout of View elements
for the pick and place example.
- The CONVEYOR and XY resources contain
the Model elements for the physical elements of the pick
and place example. An instance of the XY_MDLL type
models the pick and place mechanism, and an instance of the CNV_MDLL type
models the conveyor.
- The PRESENT sensor (workpiece present at end of
conveyor) is modeled by an instance of the V_SENSE type.
- The logic for loading and unloading a workpiece with the
electromagnet and detecting its presence there (the LOADED
sensor) is modeled by an instance of the E_LDU type inside
the composite XY_MDLL
type.
- Inter-layer communication is implemented with the local multicast pattern.
- The x- and y-axis overcurrent sensors are modeled by a
single fault signal that is published on the FAULT local
channel. This signal is set and cleared by the user by clicking
in the two-axis mechanism view, and when set causes motion to
cease immediately independent of any control actions.
- The CLOCK resource contains the simulation
clock, which is also distributed via the local multicast
mechanism.
