Fault - Device missing

Glamox Connect will warn you about missing devices by giving you fault information.

The golden rule for a device missing fault is to Investigate in the local system. Without knowing the actual state of the local system it will be hard to handle the fault in Glamox Connect.

Remember! Device missing and device not responding are not the same thing.

Device missing - fault:

Glamox Connect does no longer get any information about the device from the local system. There are multiple cases where this could happen, this needs to be investigated in the local system.

We can categorize the cause of Device missing into the following, general categories.

1. Device is broken

This will RARELY give a device missing fault in Connect.

But there are situations where this can happen, typically if the device is broken and gateway has been reconfigurated while the device is broken. E.g. if the device is broken in Ethernet2DALI and the bus for some reason has been cleared and re-addressed the fault will apear.

2. Device is removed from local system

If the local system has been reconfigured and the device has been removed, the device will NOT be automatically removed in Glamox Connect. This is to prevent unwanted loss of history.

If the device has been intentionally removed from local system it either needs to be removed or replaced Replacing device in Glamox Connect

If the device has been removed unintentionally it needs to be re-added in the local system according to the system specifications. If the device is being re-added to the same gateway as before it is likely that Connect will detect this and the fault will be closed automatically.

If the fault persists, please check to see if Connect has discovered the device as a new device. If this is the case, replace the faulty device with the newly discovered device by following Replacing device

3. Device has been reprogrammed or moved

In some cases if the device has been reconfigured in the local system it can be detected as Device missing in Connect. This most often happens if the device is moved to another gateway and Connect is not able to detect this change, especially if you have many Glamox Connect Access Points in your system.

  • If both gateways where a change occurred are on the same Access Point a race condition can occur where Connect is not able to update the parent gateway as both gateways are reporting a different state. When this is the case you will NOT get a new device as well as the fault not getting resolved. In this case the existing device needs to be removed for the new device to be discovered

  • If the gateways where a change occurred are on different Access Points you will probably get a new device linked to the new access point due to the limitation of traffic between the access points. If this is the case the device needs to be replaced by following Replacing device

Device not responding - fault:

Glamox Connect still get the device from the local system through the gateway, but it is not communicating status and responding to requests from Connect. Investigate this issue further in the local system.
