Now that I have defined my setpoint tags, I will double click on my pressure tag to bring up its tag editor. I will do the same once more and create a New Standard Memory Tag, which I will name Hi SP and give it a default value of 95 and press OK.

I will click on this plus sign here in the Tag Browser and create a New Standard Memory Tag, which I will name Lo SP and give it a default value of 20, and press OK. But before I configure those alarms, I want to define two memory tags that I will use to configure my dynamic low and high setpoint values. I want it to have a low pressure alarm and high pressure alarm. For this example, I want this pressure tag to have two alarms. Now I will close out of my alarm configuration window for just a few minutes. And with an expression binding, I have access to the entire Ignition expression language to derive my setpoint value.

With the tag binding, I have access to every tag in my gateway. I can bind the setpoint to either a tags value, or I can define an expression that evaluates to my setpoint value, therefore, making it dynamic. What I can do instead of a static configuration is bind this setpoint value by clicking on the chain link icon we see here. This setpoint value is statically configured to be 50. Now, every time my pressure value goes above 50 PSI, my alarm condition will be met and my alarm will become active.

For my pressure tag here, I can set my alarm to have an above setpoint mode and a setpoint value of 50. Here, I can add as many alarms as I want on this specific tag, but most importantly, I can define my alarms mode, which allows me to tell the system what condition must be met for my alarm to be considered active. To configure an alarm on a tag, we simply right click on the tag, select the Edit tag menu and scroll all the way down to the alarming section where clicking on the little pencil will bring up the alarm configuration window. In a previous lesson, we learned how alarms can be configured on Ignition Tags to alert Ignition users that there is something wrong in their facility.
