A common scenario beyond simply creating the alarm is propagating the alarm to the Central Gateway so it can be managed on the Edge, but present at both the Edge and Central Gateway. In Ignition 8, Cirrus Link MQTT modules used to allow for alarm configuration to be propagated from the Edge side tag to the MQTT Engine tag using the "Filtered Properties" feature. This is no longer possible as of MQTT modules version 4.0.6 due to potential timing issues around alarm evaluation at the Central Gateway that could result in incorrect evaluation. The recommended best practice for alarm propagation from the Edge to the Central Gateway is to use the Ignition Gateway Network to propagate alarms between gateways.
