Events
If a measurement object (e.g. TRMS current of a branch) crosses predefined threshold conditions
(value, direction and delay time) then an event is registered.
Following options linked to events logging are available:
• Visualization of all detected events in WebUi
• Reading event/alarm status through Modbus register
• Export via FTP and Email
In order to configure an event, specifications of the following are required:
• The threshold value
• Indication of cross direction (cross up, cross down)
• Indication of delay time
Events can be linked both to mains and branches object values:

The type of event is available on Modbus map as Alarm Status. Resolution refers to the accuracy with
which the value is defined. If several events occur for the same main or branch, the newest one will be
given out via Modbus.
Three register blocks are available in the Modbus register map:
• only object type with alarm code
• object type with alarm code and threshold value
• number of currently active alarms
