• Scaling input (1-5V, scaling, and square
root)
–5 to 105% of span (except, within –
30000 to 30000)
• Difference high limit and difference low limit
alarms
Within the measurable range
• High limit on rate-of-change and low limit
on rate-of-change alarms
A value that consists of at least one non-
zero digit. For example, 0.0001 for the 2 V
range.
The maximum value is within the
measurable range (except within –30000 to
30000).
For example, 3.0000 for the 2 V range.
For contact input, only the value of “1” can
be specified.
• Computation channels
For computation channels –9999999 to
99999999 (excluding the decimal point. Set
using an integer.)
• External input channels
–30000 to 30000
• An error occurs if p7 is set to a number of a
relay that is not installed.
• You can specify computation channels on
models with the /M1 or /PM1 math option.
• For computation channels and external input
channels, the only alarm types that you can
specify are H (high limit alarm), L (low limit
alarm), T (delay high limit alarm), and t (delay
low limit alarm).
• For computation channels, the alarm
hysteresis is fixed at zero. Use the XA
command to set the alarm hysteresis.
SW Sets the trend interval and auto
save interval
Syntax SW p1,p2,p3,p4
T-Y Display
p1 1
p2 Waveform type (specify T-Y)
p3 Trend interval (5S, 10S, 15S, 30S, 1MIN,
2MIN, 5MIN, 10MIN, 15MIN, 20MIN, 30MIN,
1H, 2H, 4H, 10H)
p4 Auto save interval (10MIN, 20MIN, 30MIN,
1H, 2H, 3H, 4H, 6H, 8H, 12H, 1DAY, 2DAY,
3DAY, 5DAY, 7DAY, 10DAY, 14DAY, 31DAY)
Query SW?
Description • You cannot use this command while recording
(memory sampling) in progress. When using
the /BT2 multi batch option, you cannot use
this command if any of the batch groups is
recording (memory sampling).
• The selectable auto save intervals (p4) vary
depending on the trend interval (p3). For
details, see the DX1000/DX1000N or DX2000
User’s Manual.
• You can only set the trend interval (p3) to 5S
and 10S for high-speed input models (DX1002,
DX1002N, DX1004, DX1004N, DX2004,and
DX2008).
• You can only set the trend interval (p3) on
medium-speed models to 15S if fast sampling
mode is enabled.
• Set the trend interval (p3) to a value less than
the scan interval.
• The p4 setting is valid when the saving
method to the external storage medium is set
to auto (using the XM command with p1 set to
AUTO).
Circular Display
p1 1
p2 Waveform type (CIRCULAR)
p3 Time length of one cycle (20MIN, 30MIN,
1H, 2H, 6H, 8H, 12H, 16H, 1DAY, 2DAY,
1WEEK, 2WEEK, 4WEEK)
p4 Auto save interval (10MIN, 20MIN, 30MIN,
1H, 2H, 3H, 4H, 6H, 8H, 12H, 1DAY, 2DAY,
3DAY, 5DAY, 7DAY, 10DAY, 14DAY, 31DAY)
Query SW?
Example Set the waveform type to CIRCULAR, the time
length of one cycle to 20 minutes, and the auto
save interval to 1 hour.
SW1,CIRCULAR,20MIN,1H
Description • You cannot use this command while recording
(memory sampling) in progress.
• The selectable auto save intervals (p4) vary
depending on the time length of one cycle
(p3). For details, see the DX1000/DX1000N or
DX2000 User’s Manual.
• The p4 setting is valid when the saving
method to the external storage medium is set
to auto (using the XM command with p1 set to
AUTO).
• Set the time length of one cycle (p3) to a value
less than the scan interval.
TI Sets the circular display offset
time
Syntax TI p1,p2
p1 1
p2 Offset time (OFF, 1H, 2H, 3H, 4H, 5H, 6H,
7H, 8H, 9H, 10H, 11H, 12H, 13H, 14H, 15H,
16H, 17H, 18H, 19H, 20H, 21H, 22H, 23H)
Query TI[p1]?
Example Set the offset time to 1 hour.
TI1,1H
Description Set the offset time to a value that is lower than
the time length of one cycle (set by the SW
command).
