3.4 Setting Commands
Example Set the external input channel 201 span to
-150.00 to 150.00.
201,ON,-15000,15000,2
Description • You can use this command on models with the
/MC1 external input channel option.
• 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).
TJ Sets memory sampling
Syntax TJ p1,p2
p1 Measurement, computation, or external
input channel number
p2 Memory sampling (OFF, ON)
Query TJ[p1]?
Example Perform memory sampling on channel 002.
TJ002,ON
Description • You can specify computation channels on
models with the /M1 or /PM1 math option. You
can specify external input channels on models
with the /MC1 external input channel option.
• You cannot use this command while recording
(memory sampling) or computation is in
progress. When using the /BT2 multi batch
option, you cannot use this command if any
of the batch groups is recording (memory
sampling).
SA Sets an alarm
When Not Using Alarms
Syntax SA p1,p2,p3
p1 Measurement, computation, or external
input channel number
p2 Alarm number (1 to 4)
p3 Alarm on/off (OFF)
Query SA[p1[,p2]]?
Example Turn Off alarm number 1 of channel 010.
SA010,1,OFF
Description You can specify computation channels on
models with the /M1 or /PM1 math option. You
can specify external input channels on models
with the /MC1 external input channel option.
When Using Alarms
Syntax SA p1,p2,p3,p4,p5,p6,p7,p8
p1 Measurement, computation, or external
input channel number
p2 Alarm number (1 to 4)
p3 Alarm on/off (ON)
p4 Alarm type
H High limit alarm
L Low limit alarm
h Difference high limit alarm
l Difference low limit alarm
R High limit on rate-of-change alarm
r Low limit on rate-of-change alarm
T Delay high limit alarm
t Delay low limit alarm
(Characters are case-sensitive.)
p5 Alarm value
p6 Relay setting
ON Relay setting on
OFF Relay setting off
p7 Relay number when p6 is set to ON
Space when p6 is set to OFF
p8 Detection of alarm (ON, OFF)
Query SA[p1[,p2]]?
Example Set a high limit alarm (alarm value = 1000) on
channel 002 alarm number 1, and activate relay
I01 when an alarm occurs.
SA002,1,ON,H,1000,ON,I01
Description • For a channel whose input range is set to
SKIP (using the SR command), p3 cannot be
set to ON.
• For a channel whose computation channel
is set to OFF (using the SO command), p3
cannot be set to ON.
• For a channel whose external input channel is
set to OFF (ER command), p3 cannot be set
to ON.
• All alarm settings on a channel are set to OFF
when:
• Its input type is changed (VOLT, TC, etc).
• Its measurement range is changed.
• Its span or scaling values are changed
during scaling display (includes changing
the decimal place).
• The channel is a computation channel,
and the channel is turned on or off or an
expression or a span value is changed.
• The h and l settings of p4 are valid only when
the measurement range is set to differential
computation between channels.
• If p4 is set to R or r, set the interval for the
high/low limit on the rate-of-change using the
XA command.
• If p4 is set to T or t, set the alarm delay for
the delay high/low limit alarm using the BD
command.
• Set the p5 alarm value in the following range
based on the p4 alarm type or the target
channel.
• Upper, Lower, Delay Upper and Delay
Lower alarms
• DC voltage, thermocouple, or RTD input
Within in the measurable range of the
selected range
• Contact input
0 or 1
