Resolution refers to the accuracy withwhich the value is defined. If several events occur for the same main or branch, the newest one will begiven 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
