Data points from networked devices are subject to additional delays based on the typical properties of the bus in question.
KNX PL-Link
A change in reliability of a KNX PL-Link data point is displayed after ca. 31 minutes. The last value remains.
The automation station queries the state of devices on the bus every 15 minutes. If a fault exists and it still remains after the next query (after an additional 15 minutes), the field devices object is set to the corresponding state. A shorter update period is not possible.
