System Log

BACnet Browser CC-ONYX System Log tab

The System Log tab shows the internal event log of the device. Each entry records a timestamped event generated by the control logic, such as a digital input change, an occupancy state change, or a button command. The log is useful to trace the behaviour of the device and to troubleshoot the sequences.
