DAQFactory alarming allows you to watch for different events that may occur within your system and flag them. This allows you to see if your system did something unusual while you were not watching. Unlike other SCADA software which only allows you to monitor for a single parameter going above or below one or two threshold points, DAQFactory allows you to create an alarm that watches for multiple conditions to occur. So where before you might only be able to alarm when the temperature of your system gets above 300C, with DAQFactory you can alarm when the temperature gets above 300C and the pressure is above 100psi. And your conditions can be much more complicated than that even.
When the alarm does occur, the alarm is logged to disk and displayed in a table. The alarm remains displayed in the table until you acknowledge that you have seen the alarm. You can also have DAQFactory play a sound, email you, call you on the phone, or perform any automated task when the alarm event occurs. You can have as many alarms as you need, and creating them is as simple as filling in a few parameters.
