19.8.2.2 Time Display
and Searching Historical Data
For sampling groups without [Add Time Data]
selected in the [Mode] tab in the common settings [Sampling], Time
Display and the search feature of historical data do not work.
Selecting the [Selected Time] check box in Historical Trend
Graph Parts displays the (Date and Time Display) option, which
displays the date and time wherever the cursor is placed on the
graph.
In [Search Status], set the Status Address for search, and
search for the historical data that you want to check.
Touch the Date and Time Display located in the
center of the graph screen to display the date and time input
dialog box.
Input the date and time of the graph data that you
want to display, and touch [ENT] to start the search.
The graph displays on the screen if there is applicable data.
If there is no applicable data, the action is as follows.
If there is no data with a specified
time
The cursor points
to the first data from before the specified time, and displays the
time for that data.
If there is no data earlier than the
specified time
The cursor points
to the oldest data and the oldest time displays.
If the specified time is newer than
the data
The cursor points
to the most recent data, and the most recent time displays.
Time Display is available when zoomed in or
out; depending on the magnification, the graph's endpoint may not
appear on the sampling display. In this case, the date and time of
the newest sampled data displays.
