This system configuration implements a mechatronic design of
the process
control example. It is the same as the TANK_MVCR
configuration, except that, as shown in the figures below, the CTL
resource containing
the CTRL
controller block (an instance of the FB_PIDR
FB type) has been moved
from the local CTRL
device to the remote TANK_VIEW
device, and the Tagged
Data has been modified accordingly, as shown in the table below.
As in the TANK_MVCR
configuration, the TANK_VIEW
device, which now contains
the Control+Model+View functions, can be launched in a separate
physical device. Hence, this configuration represents a centralized
HMI with distributed intelligent I/O such as a "smart
valve".
