I have created my digital input tags and drew the tags with widgets. However, the logging of the DI tags in the historical viewer is not shown unless I leave the Historical Viewer open. Hence, the DI data before I open the Historical viewer is not logged. As for the analog input tags, the tags are logged autonomously based on real-time values even the Historical Viewer is not open. How can I configure the DI tags to log on the historical viewer while I work on other applications?
Thanks in advance.
