Description

Remote monitoring, Alarms and Events form the foundation of any basic automation functionality. If no information is available regarding the current values of function states, operation modes, process variables, set-points, parameters, etc. it is not possible to make decisions and take action. For selected values, such as Sensor or process values, the optional provision of time-series history services is recommended.

Remote monitoring entails the capability to measure a physical/chemical/biological property. It comprises of a “raw” measurement value provided by the sensing element, a calibration function, optional signal processing/filtering and the final Sensor value which represents a real-world physical/chemical/biological property.

The remote monitoring of a property may be augmented by Alarm and Notification  functionalities which update the user regarding the monitored property value matching determined conditions (e.g., out of limits).

History services are supported to retrieve historic information on the observed properties.
