3.4 DISPLAY MODES
The display modes described below allow the currently displayed group's process values (channels, totalisers etc.-
known collectively as points) to be displayed as vertical or horizontal 'chart' traces, as vertical or horizontal bargraphs
or as a numeric value. If the
option is fitted (180 mm recorders only), the points can alternatively be
displayed as traces on a circular 'chart'. If fitted, Circular Trend display mode replaces Vertical Bargraph display
mode. The various display modes are cycled-through using the up/down arrow keys, or a specific mode (or view) can
be selected from the
'Goto View' key. If Multiple Groups are fitted, then groups can be scrolled using the
left/right arrow keys. The
key returns the user to the Home page (defined in
) from anywhere in the Operator or Configuration pages in the recorder. When dispatched, the Home page is
Group 1, vertical trend display. See also the User Screens description in section 2 of the Options Manual.
3.4.1 Vertical Trend display
This (default) display (
) shows each point in the display group as though it were being traced on a white
chart. (It is possible to display on a black 'chart' instead, by selecting Dark Trend Background in
). In either case, some thought should be given to trace colours selected in channel configuration. When se-
lected, dark background applies both to vertical and horizontal trend display modes for all Groups.
One of the channels is said to be the 'current' or 'scale' channel. This channel is identified by its diamond shaped pen
icon and by its descriptor, digital value and scale being displayed on a 'faceplate' across the full width of the screen,
above the chart. Faceplates for all the group channels can be displayed, by using the Faceplates On/Off key in the
option menu. If selected On, faceplates (showing colour, descriptor, digital value and units) for all the group's chan-
nels appear either above the current channel's faceplate or, if there are too many to fit across the screen, at the right
hand edge of the screen. When necessary, a slider bar appears to allow further (hidden) faceplates to be viewed.
Each channel in the display group becomes the 'current' channel, in turn, for approximately 10 seconds – i.e. the chan-
nels are cycled-through, starting with the lowest numbered channel. Once the final channel in the group has been
displayed for 10 seconds, the lowest numbered channel is returned to and the sequence repeats. This scrolling process
can be stopped using the Channel Cycling key in the Option menu.
To select a particular channel to be the current channel, the relevant pen icon can be touched. To cycle through the
channels manually, the faceplate area is touched repeatedly until the required channel is reached.
If a channel is included in the display group but its status is 'not good' for some reason, then its pen icon is hollow.
