3 PROCESS VARIABLE DISPLAY
The operator interface consists of a touch-sensitive screen, showing either process variable values in one
of a number of formats, or, showing confi guration or operational details for use in setting up the recorder.
This section (3) describes the process variable displays.
Section 4
describes the Confi guration displays.
Figure 3, below, depicts a typical trend display for a large-frame unit and gives details of the various
areas of the display page. The small-frame unit display is similar.
Notes:
1. Dialogue boxes, message boxes etc. cause Process Variable displays to ‘freeze’ for as long as
the box is on display. Root and Option menus (amongst others) time-out (i.e. are removed from
the display) after approximately one minute. Messages, however, are displayed until the opera-
tor takes action to remove them. It should be noted, especially, that several message boxes
may be active at one time, but only the oldest one is visible, until it is removed to reveal the
‘next oldest’ message, and so on.
2. Many of the screen components can be customised as to colour/size etc. as described in
sec-
tion 4.6.8
(Customise).
TRUNCATION OF NUMERIC VALUES
If the amount of space on the display page is insuffi cient to display the full width of the process variable
or scale value, then the displayed value is rounded down and the number of decimal places reduced. If
the width is still too restricted, the value is displayed in ‘scientifi c’ format, or if this is still too wide, the fi nal
visible character of the integer part of the value is replaced by a ‘?’ (as depicted in fi gure 3.4.4b)
