p1 Channel number
p2 Alarm number (1 to 4)
p3 Alarm on or off (On)
P4 Alarm type (H, L, TH, TL)
p5 Alarm value (within the span range)
p6 Detection (Off, On)
p7 Output
DO Output to a relay (DO
channel)
SW Output to an internal
switch
p8 Number
If p7=DO Relay (DO channel)
number
If p7=SW Internal switch number
(001 to 100)
Query SAlarmMath[,p1]?
Example Set a high limit alarm (H) on alarm number 2 of
math channel 015. Set the alarm value to 85.0.
When an alarm occurs, output to the relay (DO
channel) at number 0105.
SAlarmMath,015,2,On,H,850,On,
DO,0105
Description
• You cannot set this on a “Off” channel.
• If p3=Off, you cannot set p4 or subsequent
parameters.
• If p7=Off, you cannot set p8.
• You cannot set DO channels or internal switches
whose output type is set to Manual as output
destination numbers.
