Section 7-10
In the case of trend graphs comprising past values recorded with the logging
function, up to eight broken lines can be registered for one screen.
S
Trend graphs cannot be specified indirectly using a numeral memory table.
They must be specified by direct reference.
S
If the set sampling cycle is shorter than the time taken for display update proc-
essing, sampling results that cannot be processed in time are skipped and the
data will not be displayed correctly.
Example:
The data indicated by
marks in the graph on left cannot be pro-
cessed in time for screen updating, and is skipped; therefore only
the data indicated by
f
is displayed and the result is as shown in
the graph on the right.
