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 configuration or operational details for use in setting up the recorder. This section (3) de-
scribes the process variable displays.
describes the Configuration displays.
Figure 3, below, depicts a typical trend display and gives details of the various areas of the display page.
Note: 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 operator 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.
TRUNCATION OF NUMERIC VALUES
If the amount of space on the display page is insufficient 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 'scientific' format, or if this is still too wide, the final visible character of the inte-
ger part of the value is replaced by a '?' (as depicted in figure 3.4.3b)
