Bar Graphs
The Bar Graphs section contains four parameters, LeftBargraphMode,
CenterBargraphMode, RightBargraphMode and LeftBargraphAlarm.
Table 144 Bar Graph Block Parameters.
The left and centre bar graphs each have 30 LED segments. The right bar graph
has 20 LED segments.
By default the signals on the bar graphs are shown as traditional bars, with all
segments lit from the bottom up to the segment that corresponds to the value of
the signal. The indication can be reversed by setting the relevant parameter Left/
Center/Right/BargraphMode to ReversedBar.
A bar is an indication where all segments are lit from the bottom up to a certain
level.
A point is an indication where only two segments are lit. The topmost of the two
segments represents the value indicated.
If ReversedBar or ReversedPoint is chosen the value indicated is one hundred (per
cent) minus the value of the signal connected to the bar graph.
For example, suppose the Process Value is 40%. The left bar graph which
indicates Process Value has 30 segments therefore the number of segments lit is
given by:
