Temperature Input Unit The scaling value overflows or

ued data at time of overflow: 7FFE
hex, Temperature data at time
of underflow: 8000 hex)
Monitoring set value turns ON
immediately.
Temperature values are not
being counted even though
they meet the count condi-
tions of the zone counter.
Unit does not operate as
expected even after the com-
parator function and hystere-
sis have been set.
The temperature difference
detected by the data compari-
son between channels func-
tion is not operating properly.
The I/O comment or Unit com-
ment cannot be set.
Details Probable cause
Offset set value is too large,
so the scaled value has
exceeded the display range.
Monitoring set value is not
set appropriately.
Comparator function is not
enabled.
• The temperature display

• Data other than the temper-

Display Mode must be used
for the data comparison
between channels func-
tion.)
A comment longer than 32
characters is being set.
Decrease the offset setting so
that the scaled value does not
exceed the scaling value display
range.
Check the monitoring set value.
• Enable the comparator. (After

• Assign the temperature value to
the I/O data.
Set a comment of 32 characters
maximum.
