Troubleshooting
Section 11-1
NT631/NT631C
Symptoms
Cause
Remedy
The PC mode has
changed to the monitor
mode.
The NT631/NT631C changes the
mode when host link communication
is used.
This is an NT631/NT631C specification. When using
a PC that can also be connected using the NT link
method, use an NT link connection (there is no mode
change with the NT link method).
The graph display does
not change.
One of the percentage display
settings — “
−
100%”, “0%”, or “100%”
— is incorrect.
Set the “
−
100%”, “0%”, and “100%” values in the
following relationship:
−
100% value < 0% value < 100% value
The trend graph display
does not agree with the
actual time axis.
The cycle for graph display update
processing is longer than the set
sampling cycle.
Delete other elements on the same screen as the
trend graph that are allocated to the host and have a
high update frequency. Or lengthen the sampling
cycle.
The programming console
function cannot be used.
The communication settings are
incorrect.
Set the communication method/communication port
as follows when using the programming console
function.
- With C series PLC : NT Link : 1 : 1
- With CS1 series PLC : NT Link : 1 : N
A programming console is
connected.
It is not possible to use a programming console and
the programming console function at the same time.
Disconnect the programming console.
The PC does not support the
programming console function.
Not all PCs support the programming console
function. Check the model of PC you are using.
(6-12 “Programming Console Function”, page 237)
The memory table display
contents differ from the
initial value set at the
Support Tool.
Since the memory table is allocated
to the host memory, the display is
updated in accordance with the
contents of the host memory.
When the contents of the memory table are set as a
fixed value, do not allocate the memory table to the
host.
The battery voltage has dropped and
the data in the memory table has
been destroyed.
Replace the battery and execute “memory table
initialization”. (11-3-1 “Replacing the Battery”, page
624, and 6-4-4 “Initializing the Memory Tables”, page
161)
Since ON is set for the “resume
function”, the initial values of the
screen data memory are not written
to the memory tables.
Execute “memory table initialization”. (6-4-4
“Initializing the Memory Tables”, page 161)
If the resume function does not need to be used, use
the NT631/NT631C with the resume function OFF.
(6-9-10 “Setting the Resume Function”, page 199)
Updating of numeric
values and text is
Malfunction due to external noise
Carry out grounding work in accordance with the
conditions by referring to 3-1-4 “Grounding”, page 40.
values and text is
delayed.
There are too many numeral/text
displays on the displayed screen.
Reduce the number of numeral/text displays on the
screen for which updating is delayed.
The cycle time is extended due to
heavy processing at the host.
Shorten the host cycle time.
In an RS–422A/485 connection,
there is illegal branching or an
erroneous terminator setting.
Wire correctly by referring to Section 5 “Connecting to
the Host from the RS-422A/485 Port”.
Some of the elements
arranged on a normal
The quantity of read data exceeds
the stipulated restriction.
Check the maximum number of elements by referring
to “Display Restrictions” (page 635), create the screen
arranged on a normal
screen are not displayed.
The total of the element coefficients
for the displayed screen is greater
than 1024.
to “Display Restrictions” (page 635), create the screen
data again, then transmit all of the screen data in a
batch to the NT631/NT631C.
On an overlapping screen,
some of the set elements
are not displayed.
Since the data is transmitted from the
host in screen units, the number of
elements on the overlapping screen
has exceeded the maximum
permissible without being checked
by the Support Tool.
Check the maximum number of elements by referring
to “Display Restrictions” (page 635), create the screen
data again, then send all the screen data in a batch to
the NT631/NT631C.
