Controls on display according to touch switches
Trend graphs can be displayed in the form shown below, with associated touch
switches to control operations.
These dedicated touch switches can be used for data sampling and display op-
erations.
The relevant functions are performed once only when the touch switches are
pressed.
The positions of these touch switches can be set freely on the screen. However,
the display colors, sizes and the marks cannot be changed.
“Stop” touch switch
Stops data sampling. Updating of the trend graph display is stopped at
the same time.
While sampling is stopped, the “stop” touch switch is lit.
When the background function is used, pressing the “stop” touch switch
stops sampling in the background.
When the last data recorded before sampling was stopped is displayed,
it is displayed following the currently displayed graph.
After pressing the (stop) touch switch, if the (previous page (re-
wind)) touch switch is pressed to return to a past display and then the
(restart (continue)) touch switch is pressed to restart sampling, past
data will not be displayed and the display of new data will start again.
Example:
“Restart” (continue) touch switch
Restarts the sampling of data stopped by pressing the “stop” touch
switch. Updating of the trend graph display is started at the same time.
During sampling, the “restart” (continue) touch switch is lit.
