Every device & piece of equipment at a site can send data that the SCADA system can collect and analyze, whilst the historian logs and stores it. As a result, there are many data points. The more devices there are at a facility, the more points that need to be monitored.
What is a control system historian?
A historian is a tool that records data from the control system. But like so many other things in the manufacturing realm, that's not really sufficient. There are many types of historians that end-user manufacturers can use.Aug 20, 2019.
What is a historian in a network?
A data historian is a software program that records the data of processes running in a computer system. Organizations use data historians to gather information about the operation of programs to diagnose failures when reliability and uptime are critical..
What is a historian system?
Historian is a high-performance data archiving system designed to collect, store, and retrieve time-based information at extremely high speed..
What is the role of historian in SCADA?
The historian is responsible for storing and logging all of the data that the SCADA system aggregates. It allows operators and stakeholders to look at historical data for the plant. A historian can also have reporting capability.Nov 22, 2019.
A data historian is a software program that records the data of processes running in a computer system. Organizations use data historians to gather information about the operation of programs to diagnose failures when reliability and uptime are critical.
Historian software is often embedded or used in conjunction with standard DCS and PLC control systems to provide enhanced data capture, validation, compression, and aggregation capabilities.
PLC Historians are specialized software solutions that are commonly used in industrial settings to efficiently store and track data from Programmable Logic Controllers (PLCs). This technology is able to capture and store data in real time, allowing for detailed analysis of the production process.

From a technical standpoint, an historian is a centralized database located in the control system local area network. Historians handle data archiving and also correlate data using statistical process control techniques.
In manufacturing, an operational historian is a time-series database application that is developed for operational process data. Historian software is often embedded or used in conjunction with standard DCS and PLC control systems to provide enhanced data capture, validation, compression, and aggregation capabilities. Historians have been deployed in almost every industry and contribute to functions such as supervisory control, performance monitoring, quality assurance, and, more recently, machine learning applications which can learn from vast quantities of historical data.
