Today we study about properties of SCADA. There are various functions like TRENDS, ALARM, NAVIGATION, SECURITY etc.
SCADA ALARMS
Start a new page -->select Slider-->Three times click on sliding button and Give a tag name “D”. Then
Go to Library-->select alarm information-->Select all (ctrl A)-->Copy-->Paste on blank page
Then
Go to system-->Go to Tag database-->Choose tag name “D”-->Click on Alarm.
Now you see the blocks to fill. The alarm is set on the analog change in slider.

This chart shows that when slider is 40 then alarm shows it low, for 60 it is medium and 70 is high. The 70 is threshold position so after that alarm shows red means process is very high and we should control our system. Its tabular result of control process but we can connect buzzer to for controlling our system and get alert on exceeding its limit.
