The Check-in Interval is the frequency a sensor connects to the facility's network to send its logged readings to OneVue. Also during each check-in, pending setting updates are downloaded to the sensor.
For example, a sensor's Logging Interval may be set to every hour and its Check-in Interval is set to every 8 hours. With this configuration, every 8 hours the sensor device checks-in to OneVue and each of its hourly logged readings are sent to OneVue.
Although the Check-in Interval sets how frequency logged readings at sent to OneVue, a sensor continuously monitors its sampled readings. When a sampled out of range reading is detected, the reading is automatically sent to OneVue.
If a Primex device is solely operating on battery power, the Check-In Interval frequency does impact its battery life.
Temperature, Temperature & Humidity, Differential Pressure Sensor: estimated 18 months of battery life with an 8 hour Check-In Interval, adequate wireless signal strength, and use of high quality lithium-ion batteries.
If a check-in fails, all logged readings are stored in the sensor's non-volatile memory. A sensor device stores up to 4096 readings in its memory before it begins to overwrite the oldest reading.
Check-In Interval must be equal to or greater than its Logging Interval. The Logging Interval sets the frequency readings are stored and logged in the non-volatile memory of the device.
The following step begins by selecting the Monitored Asset assigned to the sensor, which is the recommended method. This ensures the correct sensor monitoring the asset is selected.
Go to Monitoring > Monitored Assets.
From the list, select the Monitored Asset link. Its profile is displayed.
From the sensor type section, select the type of sensor (its assigned sensor). The sensor profile is displayed.
Select the Gateway ID link of the sensor. The sensor gateway profile is displayed.
Select Show Advanced Options.
From the Check-In Interval drop-down menu, select the frequency logged readings are to be transmitted to OneVue.
The Update Pending status is set to Yes when a setting change is scheduled to be downloaded to the device during its next check-in to OneVue. Setting changes take effect when downloaded to the device. Once downloaded, its Updating Pending status is set to No.
