Configuration example

Process display
Structured as a process display, the SIPART DR21 controller can display and
monitor the process variables. If the manipulated variable y and yR is structu-
red, it can be monitored to the y display and can be adjusted with the keys (7)
and (8) with the appropriate wiring. The controlled variable x can be shown in
the red analog display (1) with structuring as x2. If the limit value A1 to A4 if
referred to x with S76, S77, S80 and shown in the green bar display (2), the
relation of the variable to be monitored to the limit values can be seen at a
glance. With the parameters dA, dE (oFPA) the variables w, x, A1 to A4 can be
displayed in their right physical variable in the w/x display (3). The y display is
made in 0 to 100%. See also fig. 3-16, page 82
