Controlling Alarm Properties of Tags and Groups at Run Time

[eyadalhanafi]

Thank you for your efforts. I would like to know if possible one can monitor and control a specific tag’s alarm information on runtime. The concept is common on most of tag based SCADA systems.

suggestions is to have something called dotfields associated with a tag, use this syntax: tag.dotfield to access (read/write) the data

Example: If you want to allow run-time changes to the Hi alarm limit on a tag named Analog_tag, you can create an Analog – User Input touch link to a button and enter Analog_tag.HiLimit as the expression in the link’s dialog box. During run time, the operator simply clicks the button and types in a new value for the Hi alarm limit assigned to the Analog_tag.

Here it sample of dotfields associated with alarm tag. .Ack Acked .Alarm .AlarmEnabled .AlarmDelay .HiHiLimit .HiLimit .LoLimit ,LoLoLimit .HiStatus .LowStatus .AlarmDesc

Hi, you mean to be able to receive the alarm object with its attributes in the script and be able to change its value?

Yes that's right but it is not necessary to receive and write values using a script. using script is one option. Use internal tags for example to link with alarm object attributes. the most important thing is to be able to change those value on runtime.
