Corrective Action
With a conventional
model, the marks
with codes FFEF to
FFF5 are used as
desired.
With a new model,
marks registered
with a conventional
model are used as
trend graph control
touch switches.
––
(1) Copy marks regis-
tered under codes
FFEF to FFF5 to
other codes with the
mark editor.
(2) Reset the marks
with codes FFEF to
FFF5 with the mark
editor. (By resetting,
the marks are re-
turned to the trend
graph control
marks.)
(3) For the elements
that use the conven-
tional marks of
codes FFEF to
FFF5, correct the
codes to those as-
signed after copying
the marks. (Refer to
8-3 Mark Editor.)
With a conventional
model, the marks
with codes FFEF to
FFF5 are not used.
With a new model,
nothing is registered
for codes FFEF to
FFF5 and trend
graph control touch
switches are not
displayed.
––
Reset the marks with
codes FFEF to FFF5
with the mark editor. The
marks of these codes
are recognized as the
trend graph control
marks. (Refer to 8-3
Mark Editor.)
Correction related to sampling cycles of trend graphs
In the conversion of the data between a conventional and a new model, conver-
sion is executed in the manner shown below due to differences of trend graph
sampling cycles.
Difference
New models:
The sampling cycle can be set in the range from 0.5 to
6553.5 s in units of 0.5 s.
Conventional models:
The sampling cycle can be set in the range from 0.1 to
6553.5 s in units of 0.1 s.

Error Message
Corrective Action
With a conventional
model, the sampling
cycle is set in units
other than 0.5 s.
With a new model,
the sampling cycle
is corrected to 0.5 s
unit cycle (corrected
to the nearest val-
ue).
[W]
Sampling cycle less
than minimum val-
ue. Minimum value
restored.
[W]
Sampling cycle not
multiple of 5. Value
rounded off to near-
est multiple of 5.
Since there are no prob-
lems in actual operation,
correction is not neces-
sary.
Correction related to the 100% value, 0% value and –100% value of a graph
In the conversion of the data between a conventional and a new model, conver-
sion is executed in the manner shown below due to differences in the range of
numeral that can be input.
