Which of the following are types of summary replication?

The types of summary replication in the context of AVEVA Historian Server serve as a way to categorize the data that is replicated based on how it is structured and the type of information being gathered.

Analog replication involves the transfer of continuous measurement data typically in the form of numerical values. This is highly relevant for capturing trends over time, as it allows for the monitoring and analysis of state changes in processes, such as temperature or pressure, where data points are recorded at regular intervals.

State replication involves capturing changes in the state of a process or system, such as whether a machine is on or off. This is commonly used for representing binary states, but it encompasses more complex states as well, while ensuring that the key transitions are logged efficiently for monitoring purposes.

Binary replication focuses on the transfer of information that can have two states, similar to state replication but typically more focused on just true/false or on/off conditions, allowing for simplified monitoring.

Event replication deals with the documentation of discrete occurrences or alerts, which may not be tied to continuous measurement but rather to specific events or anomalies in the system, providing insights into the operational events.

Thus, analog replication is distinctly a type of summary replication because it pertains specifically to the continuous data that forms the
