Types of InTouch alarms

Within the InTouch HMI, alarms are classified into general categories based on their characteristics. These categories are known as Class and Type. The Distributed Alarm system categorizes all alarms into five general conditions: Discrete, Value, Deviation, Rate-of-Change, and SPC.

You associate each InTouch tag with an alarm condition when you define the tag. Depending upon a tag’s type, you can define one or more of the alarm classes or types for it.
