Issue
How to create an offline alarm if the AS-P or RP-C loses the connection to a Zigbee sensor (SED-MTH-G-5045, SED-WDC-G-5045, and SED-WLS-G-5045) connected to AS-P or RP-C.
Product Line
EcoStruxure Building Operation
Environment
- Building Operation Automation Server Premium (AS-P)
- Building Operation Room Controller (RP-C)
- Greenpower sensors SED-CO2-G-5045 and SED-TRH-G-5045
- non-Greenpower sensors SED-MTH-G-5045, SED-WDC-G-5045, SED-WLS-G-5045
Cause
The Zigbee device will communicate the measured data with a time interval, if EBO doesn't hear the data it should mark the device as offline and generate an offline alarm
Resolution
In general, the RP-C or AS-P will listen for communication from the Zigbee device and if it doesn’t hear any communication for a certain time period, the Offline timeout (which can be specified in the properties for the Zigbee device in EBO) will set the device offline and an offline alarm will be displayed in the alarm list.
How often the Zigbee device will communicate the measured data depends on the Zigbee device.
It is possible to see and configure how often it should send the data in EBO but depending on the device it can be found in different places in EBO.
For the Greenpower sensors SED-CO2-G-5045 and SED-TRH-G-5045 it is found here:
The default value can be found in the specification sheet for the sensor.
And for the non-Greenpower sensors SED-MTH-G-5045, SED-WDC-G-5045, SED-WLS-G-5045
It can be found here:
It is possible to change the interval for how often the sensor will send the data but this may cause the battery in the sensor to drain faster.
It is recommended that the Offline timeout is set to more than twice the heartbeat interval from the sensor so that it will not be set as offline if only one message from the sensor is missed by the RP-C or AS-P.
