3.4 Setting Commands
IM 04L21B01-17EN
• If p6 is set to OFF, the relay number (p7) is
a Don’t care value in setting commands. In
queries, this parameter will always be returned
as a space.
• An error will occur if p7 is set to a number of a
relay that is not installed.
• Parameter p8 is valid when No logging under
Alarm is set to “On” in basic setting mode.
When parameter p8 is invalid, it is a Don’t
care value in setting commands. In queries,
this parameter will always be returned as “On.”
• Parameter p9 is valid on models with the Log
scale (/LG1) option.
• Parameter p9 is valid when p1 is set to a
measurement channel.
• Use parameter p9 to set the alarm value’s
exponent.
• When using a channel that is not set to Log
scale (/LG1 option):
In setting commands, this parameter is a
Don’t care value. In queries, this parameter
will always be returned as 0.
• When using a channel that is set to Log
scale (/LG1 option):
If the mantissa of the alarm value is 100:
–16 to 16
If the mantissa of the alarm value is a value
other than 100: –16 to 15
• You can specify computation channels
(including in queries) on models with the /M1,
/PM1, or /PWR1 math option.
• For computation 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).
SW Sets the trend interval and auto
save interval
Syntax SW p1,p2,p3,p4
p1 1
p2 Waveform type (T-Y)
p3 Trend interval (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[p1[,p2]]?
Example Set the trend interval to 5MIN and the auto save
interval to 1H.
SW1,T-Y,15MIN,1H
Description • You cannot use this command to configure
settings while recording (memory sampling) is
in progress.
• The selectable auto save intervals (p4) vary
depending on the trend interval (p3). For
details, see the FX1000 User’s Manual, IM
04L21B01-01EN.
• You can specify 15S on the high-speed input
models.
• Set the trend interval (p3) to a value less than
the scan interval.
TW Sets the secondary trend interval
Syntax TW p1
p1 Trend interval (15S, 30S, 1MIN, 2MIN,
5MIN, 10MIN, 15MIN, 20MIN, 30MIN, 1H,
2H, 4H, 10H)
Query TW?
Example Set the trend interval to 2 minutes.
TW2MIN
Description • Set the trend interval (p1) to a value less than
the scan interval.
• You can specify 15S on the high-speed input
models.
