Freelance Trend Server 2019 Problem - No Trrend Server data in DigiVis
In Freelance 2019, trends work fine when we create them under DigiVis object, but the customer wants Trend Server to be existed in the project configuration. We followed the instructions in the Trend Server manual (3BDD012527-111_B_en_Freelance_Engineering_Trend_Server), we could not achieve to make it run on DigiVis trends. There is also OPC server in the project configuration and it is combined with Trend Server. OPC Server is working fine and Trend Server is also shown as running in the project tree in the commissioning mode but in any DigiVis station, it is not possible to see the actual data in the user defined trends.
Prompt replies will be appreciated since we are in the FAT days.

please check that the Trenserver PC is on the same time with Process Station and Operator Station. Time-Synchronization should be On for the PC that runs the Trendserver.
If the time is off in the Trendserver, data might be in the history of the trend (try zoomin out) or worse, in the future.
Be sure to set the time synch as admin, otherwise Settings might show it is on, but it is not.
Also check that you have installed the OPC tunnel on the Trendserver PC. Freelance Operation needs the OPC tunnel to access the Trendserver, even if they run on the same PC.
