Description

The monitoring occurs by four different monitoring modes. Furthermore, devices can be combined in up to 5 groups for monitoring purposes.

Monitoring mode: Poll physical address cyclically. With this mode of monitoring the unit cyclically polls the physical address of the devices to be monitored to ensure that they are still present. The EUB/S sends a polling request to the device to be monitored. If the device is present and in operation it will respond and the EUB/S detects the device. If there is no response after a certain time, the EUB/S evaluates a failure. 

Monitoring mode: Poll physical address by object. With this mode of monitoring the devices to be monitored can be polled by other bus members in the KNX system. For example, devices can be polled via a pushbutton or a time switch at a certain time. If a connection cannot be established to the monitoring device, it will be evaluated as a failure.

Monitoring mode: Receive group address cyclically This mode of monitoring is also referred to as passive monitoring. Telegrams which are cyclically sent by the device being monitored are evaluated. If the telegrams are not received for a definable time, it will be evaluated as a failure. For this monitoring mode it is necessary that the devices being monitored can send telegrams cyclically.

Monitoring mode: Poll group address cyclically This mode of monitoring is also referred to as active monitoring. With active monitoring the EIB Monitoring Unit cyclically sends telegrams to the device to be monitored and evaluates the telegrams received. If the KNX Monitoring Unit does not receive a response telegram within an adjusted time, it will be evaluated as a failure.
