Troubleshooting Inability to Select Specific Times on FactoryTalk View SE Trend Graphs

Question:

Greetings, Following a recent upgrade of our control server to a newer model, we have encountered issues with our trend graphs. Previously, we could select any time on the graph to view the recorded tag values. However, after the transition, the graph now only displays a limited number of random times, making it difficult to access specific data points. For instance, when trying to view the value at 4:40 pm, the graph may only show the next available data point at 4:51 pm. While some trends are functioning as expected, the majority are not. Despite no coding changes during the server upgrade, the issue persists. Our data is stored in a SQL database. We are seeking a solution to restore functionality and allow operators to freely select any time on the trend graph to retrieve the tag values. Can you assist us in resolving this issue?

What does upgrading a control server entail? Does it involve hardware upgrades, updating the operating system, or upgrading the FTSE version? What type of architecture does the server have - distributed, standalone, etc.?

robertmee inquired about the meaning of upgrading a control server. Does this involve upgrading PC hardware, the operating system, or the FTSE version? Additionally, what is the architecture - distributed, standalone, etc? It seems like there was an upgrade to both the operating system and the FTSE version (currently at V12.00). However, details about the architecture and whether it is distributed or standalone are still unclear.

It sounds frustrating to deal with limited data visibility after an upgrade when everything was working fine before! Have you checked if the upgrade changed any settings related to data interpolation or sampling rates? Sometimes default settings can change during a transition, which might limit the data points being displayed. Also, ensure that the data retrieval queries pulling from the SQL database are still optimized for the updated server—sometimes performance tweaks can inadvertently affect how data is accessed. If it persists, reaching out to your server or software provider's support team could also yield insights tailored specifically to your setup.

It sounds like a frustrating situation! Since you mentioned that there were no coding changes, it might be worth checking the configuration settings of your new control server to see if there are any default parameters that could be affecting how data points are displayed on the trend graphs. Additionally, consider looking into whether the SQL queries used to fetch data from the database might need adjustments due to any differences in the new server's setup. Sometimes, simply tweaking the time resolution or aggregation settings in the graph parameters can make a big difference. Have you confirmed if any other users with similar setups are experiencing this issue? It might help to reach out to your server's support team for further guidance as well. Good luck!
