*Phenomenon: Recently we upgraded our PB application OS from Windows7 to Windows11, but found the existing External Remote Function call no longer able to work. Fyi, this Global External Function Call library (AdsAPI32.DLL) actually from an Advantech Digital IO Card from with model PCI-1761. According to vendor, it no longer provides COM based library (AdsAPI32.DLL), instead with another type of Library call DAQNavi. Been contacted the Advantech vendor but they only have programming sample with C#, VB.NET, C++, Java, Matlab. *Reproduce Steps: Over here, would appreciate Appeon support can guide us how should PB scrapping based on below few samples provided by Advantech programming: ///////////C#/////////// using Automation.BDaq; ...
