Description
On Time Checked/

Checked
Turns on/off publishes from the node at a settable value
independent of the Measurement Interval.
Publish Minute

Day Minute
Defines the publish interval of the node. The Measurement
Interval set in Node Configuration is still polling the I/O.
On Value Checked/
Not Checked Not
Checked
Turns on/off publishes from the node when a trigger Rule has
been met.
Fast Mode On/Off Off
With Fast Mode On, when a trigger Rule has been met, the
Measurement Interval and Publish Interval for the node is set
to the value set in the Measurement Interval field. It will stay
set to this interval until the trigger Rules are no longer true or
until the time specified in the Duration field.
Measurement
Interval 10s to
84,600s
(24 hours)
None
In the Measurement Interval field, specify the temporary
Measurement Interval to be used while a trigger Rule is met.
Duration 10s to
84,600s
(24 hours)
None
In the Duration field, specify how long you want the
temporary Measurement Interval to be in effect.
Add Rule Click N/A
Click to add a trigger rule.
Trigger Rules:
• Select whether you want to start receiving data when an input exceeds a certain value or falls
below a certain value.
• Select which input on the node to which you would like to apply the rule.
• Enter the Threshold value to be exceeded in order for the trigger Rule to be true. Values should
be entered in Engineering Units
• Enter a value of hysteresis you would like to exceed before the trigger Rule is no longer true.
Hysteresis values are entered as a percentage of the Threshold value.
Ex.: I have a refrigeration unit storing ice cream and I continuously monitor the temperature with a Wzzard
Mesh sensor and a cellular gateway. To save on cellular data, I’d like to know the temperature only once
a day unless it goes above my acceptable maximum temperature of +6 degrees Fahrenheit, in which
case I want a report of temperature every minute for an hour or until my temperature is back in range.
• Have the temperature input node set to a 1 hour measurement interval and reporting in Degrees
Fahrenheit.
• Click the On Time check box to enable On Time publishes.
• Set the Publish interval to publish the last sample every Day.
• Click the On Value check box to enable publishing when trigger Rules are true.
• Click to turn on Fast Mode.
• Set my temporary Measurement Interval to 60s (1 minute).
• Set my Duration to 3600s (1 hour).
• Add a rule that sets HI, Temp1 >= 6, 10% hysteresis.
• Click to review and save the changes.
