Example Set a high limit alarm (H) on alarm number 2 of
channel 0001. Set the alarm value to 1.8000V.
Use the alarm detection function. When an
alarm occurs, output to the relay (DO channel)
at number 0205.

Description
• You cannot set this on a “Skip” channel.
• If p3=Off, you cannot set p4 or subsequent
parameters.
• If p7=Off, you cannot set p8.
• For the alarm values of p5, use the values in the
following table.

Example Set a 0.5% hysteresis on alarm 3 of channel
0002.
SAlmHysIO,0002,3,5
Description
• Hysteresis specified for delay high and low limit
alarms (TH and TL) and high and low limits on rate-of-
change alarms (RH and RL) do not apply.

Example Set the channel 0001 alarm delay time to 2
minutes 30 seconds.
SAlmDlyIO,0001,0,2,30
Description
• Set the delay time so that it is an integer multiple of
the scan interval ( SScan command).
STagIO
Tag
Sets a tag to an AI, DI, or DO channel.
Syntax STagIO,p1,p2,p3
p1 Channel number
p2 Tag (up to 32 characters, UTF-8)

Query STagIO[,p1]?
Example Set the channel 0001 tag to “SYSTEM1” and
the tag number to “TI002.”
