Updated Historian software from Rockwell Automation offers faster, more secure data access

Production workers can now more quickly access the data they need using the FactoryTalk Historian Site Edition (SE) software from Rockwell Automation. According to Rockwell, the new enhancements make it the most reliable and secure release of the software to date.

To help users more quickly access data, the software now uses client-side connection balancing and failback. This balances user connections across multiple servers, instead of connecting them all to a primary server. In larger systems, where many people are making queries for data that can go back several years, this can reduce server demand to help users access data in seconds instead of minutes.


The FactoryTalk Historian SE software also now offers user-based archive scheduling. This function allows users to schedule historical archiving during down periods or off hours. It reduces the risk that archiving occurs during critical processes, when it can affect server performance and slow access to data.

To better secure production data, all subsystems within the FactoryTalk Historian SE software are now configured to run under least-required privileges. This minimizes the potential damage unauthorised users can do if they penetrate a system.

The software also now supports the latest operating systems, such as Windows Server 2019. This can extend the life of systems, which can be especially valuable for operators of validated systems in regulated industries.

The new FactoryTalk Historian SE software release is part of PlantPAx 5.0, the modern distributed control system (DCS) from Rockwell Automation, and uses the same FactoryTalk Services as other software included in the DCS. This minimises the potential for conflict or errors and helps make installation easier.
