[Trend] Dialog
[Setting 3] Tab Window
Two lines are added to both upper line and lower line.
This menu is available when [Upper Line 2 Display] or [Lower Line 2 Display] is clicked. The
properties like [Data Length] or [Graph Max./Min.] are specified in the [Setting 2] tab window.
The settings are the same as the present [Upper/Lower Line].

Asynchronous Display of Multiple Trend Graphs (corresponds to page 10-27)
In the ZM80, all the trends on a trend graph is displayed to the same points at the same timing,
because a trend graph has only one control memory.
If you want to display each trend at the asynchronous timing, you have to make another trend
graph to overlap the original trend graph for setting another control memory.
However, it may be that the trends are deleted or displayed at every redrawing by the [Redraw]
bit or the [Redraw after clear] bit to give the order of each control memory priority.
To avoid the above condition, the order of priority for each control memory is decided by linking
two or more overlapped trend graphs.
For example, when drawing two trend graphs as follows;
Division No. : 0
Control Memory : D120
Process Cycle : High Speed
(=Master Trend Graph)
1) D120 = H0009
(Number of trend counts)
2) D140 = K9
(Number of trend counts)
Division No. : 1
Control Memory : D140
Use Link
Link Division No.
Process Cycle : High Speed
(=Slave Trend Graph)
3) D140 = K5
(Number of trend counts)
D120 = H8007
(Redraw after clear
/ Number of trend counts)
The master trend graph is
drawn at the 9 points.
The slave trend graph is
drawn at the 9 points.
Change the number of counts to
5 points in the slave trend graph,
and send both changing the
number of counts to 7 points and
the [Read after clear] command
in the master trend graph at the
same time. At the same time,
the 5 points of the trends in the
slave trend graph is drawn.
