UA Expert client taking data from UA Gateway very slow
Posted: 13 Mar 2023, 13:03
Hello,
I have installed the latest versions of UA Gateway and UA Expert. My intention is to test the efficiency of the software before making a multi-license purchase. I wanted to know the CPU load and refresh rate. The server is a Siemens WinCC 7.5 OPC DA. I need to read 15,000 tags. I have been creating configurations with 100 and 500 tags and it ends up reading fine. The problem is that opening and subscribing the variables takes a long time. When I put the 15.000 tags it took 10 minutes to make the first refresh to the UA Expert. After that it stays frozen until the next refresh, which can be every three or four minutes. I do not know if it is a problem of the DA WinCC OPC data server or a problem of the UA Expert performance with so much data. The client is a Windows 7 ultimate and the server is a windows server 2008 R2.
Tanks
