1.5.4 Controller types (S1, S49 to S53)
-- Display range
The digital displays are four-digit 7-segment displays, the display range of which can be set
in double controllers and process displays (S1
two display levels I and II separately, with the parameter dP (decimal point), dA (start value)
and dE (full scale) in the structuring mode oFPA.
In single controllers (S1 ≤4) the parameters of the display level II are followed up to the
parameters of the display level I and are not adjustable.
With dAI or dAII the numeric value is set which is to be displayed at arithmetic value 0
(corresponding to 0 % display in the analog displays). With dEI or dEII the numeric value is
set which is to be displayed at arithmetic value 1 (corresponding to 100 % display in the
analog displays). With dPI or dPII the decimal point is set as a fixed point. If the starting
point is set less than the full scale, a rising display is given with increasing arithmetic values
and vice versa. The numeric range for the start and end values goes from -1999 to 19999,
beyond these numbers -oFL and oFL is displayed in the case of overmodulation in the
process operation level. The factory setting is 0.0 to 100.0 %.
With the refresh rate parameter dr (onPA) the digital displays can be calmed down in the
case of restless process variables. Non-linear process variables can be represented physi-
cally correctly by the linearization.
The display range set with dP, dA and dE is transferred depending on the controller type
(S1) to the parameters and setpoints which can be assigned to the displayed variable:

Display format of parameters and setpoints assigned to the displays
With the appropriate asisgnment, this also applies to the limit value alarms A1 to A4, see
chapter 1.5.9, page 124.
The analog displays have a fixed display range of 0 to 100 %. The overshoot or undershoot
is displayed by the flashing 100 % or 0 %-LED. Display is by one or two alternately flashing
LEDs. The center of the illumination field represents the "pointer". This display technique
doubles the resolution. If a falling characteristic is set for the digital displays (d*E<d*A), the
analog displays are switched in direction of effect except for the ratio controllers.
