[ISS Support Case] Historian Connection

Last updated: October 17th, 2025

Description

Client is having an issue acquiring data from the Historian. Attempts to "drop database" and configure from configurator result in error. Data acquisition section of Historian is showing data is being acquired from the wrong node. Client is not able to access data in Historian Trend or via SQL Query. Viewing the runtime database in SSMS does not show the database tables so there appears to be an issue with the runtime database.
