SA Alarm Settings
Setting When p3=OFF
SAp1,p2,p3
When p3 is not OFF
SAp1,p2,p3,p4,p5
When Alarms are OFF
Setting SAp1,p2,p3
p1 Channel range (001 to 060 and A001 to
A300)
p2 Alarm number (1 to 4)
p3 Alarm type (OFF)
Query SA[p1[p2]]?
Example Turn OFF alarm number 1 on channel 10.
SA10,1,OFF
Explanation • If the /M1 MATH function option is not included,
MATH channel settings cannot be performed
(including queries).
• Specify measurement channels on 001 to 060 of p1.
With Alarms
Setting SAp1,p2,p3,p4,p5
p1 Channel range (001 to 060 and A001 to
A300)
p2 Alarm number (1 to 4)
p3 Alarm type
H
Upper limit alarm
L Lower limit alarm
DH Differential upper limit alarm
DL Differential lower limit alarm
RH Upper limit on rate-of-
change alarm
RL Lower limit on rate-of-
change alarm
TH Delay upper limit alarm
TL Delay lower limit alarm
p4 Alarm value
p5 Relay number
OFF
No relay setting
001 to 060 Relay number
Query SA[p1[p2]]?
Example Set alarm number 1 on channel 2 to upper limit alarm
(alarm value 100.0), and set relay number 12 to
operate upon alarm occurrence.
SA002,1,H,1000,012
Explanation • If the /M1 MATH function option is not included,
MATH channels (A001 to A300) cannot be set
(including queries). However, if the pulse input
module is installed, MATH channels (A001 to A060)
can be set (including queries).
• Specify measurement channels on 001 to 060 of p1.
• When the input range setting (SR command) is SKIP,
p3 cannot be set to anything other than OFF.
• In the following case, all alarm settings for the
channel are OFF.
• Changing the input type, measuring range, and
MATH type
• When scaling, changing the scaling values
(including changing the decimal place).
• Turning MATH channels ON/OFF and changing
expressions.
• The p3 DH and DL setting are only valid when the
MATH type is difference between channels.
• If p3 is set to RH or RL, set the interval time for high
limit/low on rate of change using the XA command.
• If p3 is set to TH or TL, set the delay time using the
BD command.
• See the table in section 1.3 for the alarm value
setting range for p4.
• For information on how to add relay numbers, see
the main manual.
• For MATH channels, the alarm types that can be set
are H (upper limit alarm), TH (delay upper limit), TL
(delay lower limit), and L (lower limit alarm) only.
• Set the output type for relays to alarm using the XD
command, and set the relay numbers to p5.
• p3 and p5 cannot be changed while recording.
VA Alarm Hysteresis Settings
Setting VAp1,p2,p3
p1 Channel range (001 to 060)
p2 Alarm number (1 to 4)
p3 Hysteresis value
Query VA[p1[p2]]?
Example Set alarm number 1 on channel 2 to hysteresis value
100.
VA002,1,100
Explanation • Specify measurement channels on 001 to 060 of p1.
• If the alarm type is high limit/low limit on rate-of-
change alarm, the hysteresis setting is invalid.
• See section 1.3 for the setting ranges for hysteresis
values.
• If the alarm setting is no alarms, this cannot be set.
XA Settings Related to Alarm
Setting XAp1,p2,p3
p1 Rate-of-change limit on increase
interval (1 to 32)
p2 Rate-of-change limit on decrease
interval (1 to 32)
p3 Alarm status hold (OFF/ON)
Query XA?
Example Set the rate-of-change limit on increase interval to 10
and the rate-of-change limit on decrease to 12. Hold the
alarm status.
XA10,12,ON
Explanation Interval is set using the units of the measurement
interval. The measurement interval is set using the XV
command.
