Bar graph setting example
(BAR_GRAPH_SELECT, EACH_BAR_GRAPH)
The bar graph in the lower field on the LCD allows
the user to select either (BAR_GRAPH_SELECT)
to display all IN_xx (xx:01 to 16) or to display
an individual selection of inputs (EACH_BAR_
GRAPH). Bar graphs display upper and lower limit
values according to values scaled using INxx_
SCALE (xx: 01 to 16).
In a batch bar graph setting, setting BAR_GRAPH_
SELECT=0: All are set to inactive will turn off all bar
graph displays and setting 2: All are set to active will
display bar graphs on all screens.
When bar graphs are enabled, the lower display
field will alternately display Sub Tag, communication
status and bar graphs in stated order according to
the interval set by DISPLAY_CYCLE.
Scroll bar display setting (V_SCROLL_BAR)
Use V_SCROLL_BAR to set the scroll bar display
setting. Set V_SCROLL_BAR = 0: Inactive to turn
off the scroll bar display and set it to V_SCROLL_
BAR = 1 Active to have it on at all times. Selecting
V_SCROLL_BAR = 2: Knob link will turn on the
scroll bar display only during display switching and
turns off the display within a few seconds.
