This system configuration implements the View
development step of the process control
example for the MVCD
engineering methodology. In this configuration, a single Device (TANK_VIEW)
contains Resources for both the View (PROCESS)
and HMI (LABELS, SLIDERS)
elements.
When this system configuration is opened and launched
from the process
folder of the FBDK, the
sliders can be used to to adjust the values of the View
elements.
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.
