Log triggers are part of the overarching features Historical data en Datalogging to MQTT broker. With log triggers you can create custom triggers to log data on. Useful to log data at machine-specific events. For example when a certain temperature has been exceeded, an error occurred, or when a product leaves a conveyor.
When the trigger condition is met, all tags that use this trigger are logged once. The tags will be logged again, once, the next time the trigger condition becomes true. Meaning the trigger condition first needs to become false. In the example above the tags are logged when the temperature exceeds 60°C, which happens twice.
Add log triggers
Add a log trigger for every unique trigger moment. Note that you can use the same log trigger for multiple tags to log them all at the same moment.
