NT631/NT631C
Symptoms
The contrast is too high.
Malfunction due to external noise
There are too many numeral/text dis-
plays on the displayed screen.
The cycle time is extended due to
heavy processing at the host.
In an RS-422A/485 connection, there
is illegal branching or an erroneous
terminator setting.
The quantity of read data exceeds the
stipulated restriction.
The total of the element coefficients
for the displayed screen is greater
than 1024.
Since the data is transmitted from the
host in screen units, the number of
elements on the overlapping screen
has exceeded the maximum permis-
sible without being checked by the
Support Tool.
Display System Menu under Change
System Settings in the System
Installer mode is set to Disabled.
Screen Memory Protect under
Change System Setting in the Sys-
tem Installer mode is set to Disabled.
Screen Memory Protect has been set
to Disabled because the PT power
supply was turned OFF during dele-
tion of screen data.
The upper/lower (max./min.) limit
check for numeric value input is in
effect.
Bit 5 of the PT status control area
(numeral/character string input) is set
to 1 (ON).
The interlock function is set for the
input field and the controlling interlock
bit is OFF.
Bit 6 of the PT status control area (PT
window opening) is set to 1 (ON).
Bit 4 of the PT status control area (PT
screen switching) is set to 1 (ON).
The interlock function is set for the
touch switch and the controlling inter-
lock bit is OFF.
Cause
Carry out grounding work in accordance with the
conditions by referring to 3-1-4 Grounding, page 34.
Reduce the number of numeral/text displays on the
screen for which updating is delayed.
Shorten the host cycle time.
Wire correctly by referring to SECTION 5 Connecting
to the Host from the RS-422A/485 Port.
Check the maximum number of elements by referring
to Display Restrictions in Appendix A of the Refer-
ence Manual, creating the screen data again, and
transmitting all of the screen data in a batch to the
NT631/NT631C.
Check the maximum number of elements by referring
to Display Restrictions in Appendix A of the Refer-
ence Manual, creating the screen data again, and
then sending all the screen data in a batch to the
NT631/NT631C.
In the System Installer mode, set Display System
Menu to Enabled (page 147).
In the System Installer mode, set Screen Memory
Protect to Enabled (page 147).
Do not turn the PT power OFF during deletion of
screen data.
In the System Installer mode, first change the setting
for Screen Memory Protect to Enabled, then repeat
the screen data delete operation (page 148)
Check the screen data’s upper/lower (max./min.) limit
check setting for numeric value input, and correct it if
necessary. Refer to 2-12 Inputting Numeric Values in
the Reference Manual for details.
Reduce the contrast (page 187).
Set bit 5 to 0 (OFF). Refer to 2-2-1 PT Status Control
Area (Host ↔ PT) in the Reference Manual for
details.
Inputs are prohibited in input fields when the corre-
sponding interlock bit is OFF. Check the status of the
corresponding interlock bit and turn it ON.
Set bit 6 to 0 (OFF). Refer to 2-2-1 PT Status Control
Area (Host ↔ PT) in the Reference Manual for
details.
Set bit 4 to 0 (OFF). Refer to 2-2-1 PT Status Control
Area (Host ↔ PT) in the Reference Manual for
details.
Touch switches are disabled when the corresponding
interlock bit is OFF. Check the status of the corre-
sponding interlock bit and turn it ON.
