Please refer to the following for models that
support the XY Block Display Scatter Graph.
1.5 Supported
Features
-
For Historical Trend Graphs, Data Block Display
Graphs, XY Historical Scatter Graphs and XY Block Display Scatter
Graphs, you can display up to 8 graphs on a single screen
(including called screens and popup windows) at the same time.
-
For Historical Trend Graphs, Data Block Display
Graphs, XY Historical Scatter Graphs and XY Block Display Scatter
Graphs, you can display up to 40 channels on a single screen
(including called screens and popup windows) at the same time. Any
subsequent channels do not display.
-
The maximum number of channels that can be
displayed on a single XY Block Display Scatter Graph is 10.
-
You can display up to 512 coordinates (number of
data).
-
Coordinate points of the graph data are
calculated as a value between 1 and 1,000. Even though values may
be outside the display range, if the converted values are within
range, they will display in the graph.
-
Do not draw other parts in the graph display
area. to draw pictures such as lines directly within the display
area, place the graph on base screen 9000 to 9999. If you draw
scale lines within the graph display area on base screens 1 to
8999, the scale lines will not show on the display unit. to display
a graph with scale lines on base screens 1 to 8999, load screen
9000 or higher.
On screen 9000 or higher, draw the graph and objects that overlay
the graph. Other parts such as switches may not operate
properly.
-
When using the graph area color with a graph with
no shape on base screen 9000 or higher, drawing is done in the
following order. As a result, if you draw on the graph display
area, or you set the base screen's background color, these draw
with a higher priority than the Graph Area Color.
-
Graph Area Color
-
Drawings such as Line or Rectangle, or Base
screen background color
-
Graph
-
Graph will not be displayed when there is invalid
data in either X-axis or Y-axis.
-
Since the calculation method of the coordinates
of [Scale] and [Auxilary Line] are different, the coordinate
position may be different even if the values are same.
-
If there are multiple channels, when the clear
bit for one channel is turned ON (store "2" in the control
address), the graphs for all channels will be cleared.
When you display the graph again after clearing the bit (store "3"
in the control address), the graph only displays the specified
channels after all channels are cleared. If the same address is
specified for multiple channels, only the channel for which a graph
is displayed at last will be displayed. In order to display
multiple channels at the same time, display each channel after
clearing all channels.
-
When dislaying multiple data block display graph
or XY block display scatter graph on one displayed screen, do not
duplicate each part's control address.
-
The display speed of graphs differs depending on
the location of the [Control Word Address]. Whether you use a
device/PLC address or use the read area (LS0020 or higher) of the
display unit internal devices. The difference in display speed is
same as the Data Block Display Graph. For more details, please
refer to the following.
19.10.3 Data Block
Display Graph Structure, When setting a device/PLC address
-
When [Show Scale] is set to [Address] and a
communication error occurs, drawing is done using a value of
[0].
-
When the auxiliary line is set to [Address] and a
communication error occurs, drawing is done using a value of
[0].
-
When the display is updated, the graph display
area is filled in with a clear color and then the graph is
displayed again. Therefore the screen may flicker.
-
You cannot use symbol variables set up as an
array in the graph display.
