Select the configured alarm that you want associate a high setpoint with. If you don't have a configured alarm, you will need to create one. Scroll down to Alarms, and click on the Edit icon next to your alarm to open the Alarm UI.Use an OPC Tag and rename it to Tank Level.Create two Memory Tags calling one High SP with value of 85, and another one called Low SP with a value of 20.Let's alarm the tank level when the setpoint goes above 85 and below 20. The Tank Level will use the values in the Memory Tags as the high and low setpoints. This example uses an OPC Tag called Tank Level, and two Memory Tags called High SP and Low SP. Rather than hardcoding a value in the high and low Setpoint properties, you can bind them to either a Tag in the system or an Expression to make them dynamic. ![]() Suppose you want to alarm a Tank Level if it goes above or below a certain setpoint. ![]() ![]() To Configure Dynamic Setpoints on an Alarm You can configure alarms with dynamic setpoints inside of a Tag definition. It is similar to configuring an alarm, however, configuring an alarm with a dynamic setpoint requires additional Tags to serve as these setpoints. A good example of this is when an operator changes a high or low setpoint, it also changes how the alarm is evaluated.
