Trigger
You use the triggers to specify the conditions that initiate the transfer of the value saved in
the device to the broker.
Up to two triggers can be selected per data point. The following trigger classes can be
configured:
●
Time trigger
– Cyclic
Cyclic transmission - configurable cycle
– Time
Once daily / Once weekly / Once monthly
●
Value trigger
– Deviation: Transmission in case of deviation from the last stored value
– Threshold LOW: Transmission if value is below the threshold
– Threshold HIGH: Transmission if value is above the threshold
– Range within: Transmission when the value enters a value range
– Range outside: Transmission when the value leaves a value range
●
Input trigger
– Digital input
Transfer upon edge change at the digital input
You can combine two triggers for each data point. When two triggers are configured, the
transfer is initiated as soon as one of the two trigger conditions is met.
Not all trigger types can be combined for a tag in practice. The following trigger combinations
are supported:
