This System Configuration implements the Model+View testing step for the process control example.
You can launch
this configuration from the FBDK
and use the sliders to adjust the
VALVE
and
PUMP
settings in the range {0..100}%. The
TANK
will rise and fall at a rate proportional to the difference between
the
VALVE
and
PUMP
settings.
This System configuration uses the Local Multicast design pattern for the communication of data and events among Resources. The FBDK uses the Tagged Data design pattern to ensure consistency of the communicated events and data, as shown in the table below.

RECORDER device provides HMI functionality
via an instance of the STRIP3
class to record the system's dynamic behaviors.
TANK_VIEW device provides combined Model,
View and HMI functionality.
The TANK_VIEW.PROCESS
resource is configured identically to the TANK_VIEWL
system configuration to provide View functionality.
The TANK_VIEW.SLIDERS resource provides the HMI
functions for the setting of valve position and pump speed.
The TANK_VIEW.CLOCK, TANK_VIEW.PUMP_MDL and TANK_VIEW.TANK_MDL
Resources provide the simulation clock and Models for the
dynamic behavior of the Pump and Tank, respectively.
