Set IOChannel
range
Specify the temperature range that you want to measure. For RTD, the range is:
z 1 (Pt100 a=385 -50 to 150C) This is the default.
z 2 (Pt100 a=385 0 to 100C)
z 3 (Pt100 a=385 0 to 200C)
z 4 (Pt100 a=385 0 to 400C)
z 5 (Pt100 a=385 -200 to 200C)
z 6 (Pt100 a=392 -50 to 150C)
z 7 (Pt100 a=392 0 to 100C)
z 8 (Pt100 a=392 0 to 200C)
z 9 (Pt100 a=392 0 to 400C)
z 10 (Pt100 a=392 -200 to 200C)
z 11 (Pt1000 a=385 -40 to 160C)
z 12 (NiFe604 a=518 -80 to 100C)
z 13 (NiFe604 a=518 0 to 100C)
For thermocouple, the range is:
z b (B 500 to 1800C)
z e (E 0 to 1000C)
z j (J 0 to 760C) This is the default.
z k (K 0 to 1370C)
z r (R 500 to 1750C)
z s (S 500 to 1750C)
z t (T -100 to 400C).
alarm
Configures alarm settings when the Analog input trigger is activated.
level
You can specify up to five alarm trigger/clear severity levels. If the Trigger Type is
Low , an alarm is triggered when the input drops below the specified Trigger value;
other severity level trigger values must decrease in value with each subsequent level. If
the Trigger Type is High , an alarm is triggered when the input is higher than the
specified Trigger value; other severity level trigger values must increase in value with
each subsequent level. To clear an alarm, the input must drop below the specified value
when Trigger Type is High or go above the specified value when Trigger Type is Low .
mode
Enables/disables an alarm level. The default is off.
trigger-type
If the Trigger Type is Low , an alarm is triggered when the input drops below the
specified Trigger value; other severity level trigger values must decrease in value with
each subsequent level. If the Trigger Type is High , an alarm is triggered when the input
is higher than the specified Trigger value; other severity level trigger values must
increase in value with each subsequent level.
trigger-level
Specify the value that will trigger an alarm, the measurement is based on the Type and
Range that you specify. This value must not fall within the scope of the value used to
clear an alarm.
