ALARMING IN HMI BASIC
Alarm in HMI Basic are displayed instead of time indication
in a form of a letter and number, like AL15. The number is
given to identify what is the source of alarm.
Note! HMI Basic cannot acknowledge alarms. All non-
remanent events will disappear automatically. All remanent
events need to be reset by means of HMI Advanced, or by
switching off / on the power supply.
