The Charm plug-in has three Triggers that become active when messages are received.
When the Charm reader sends data, a transfer is triggered. The analytical data is made available in data fields.
In order to monitor and control devices, a heartbeat can be received. The heartbeat can be set up as trigger: As soon as a heartbeat occurs, a trigger becomes active that prompts a transfer. This can be used to document the online status of a device or to prompt an error message alert, for instance.
If errors are detected, a trigger becomes active. This makes it possible to target errors specifically in order to solve problems quickly.
