We use OPC DA with a 184.108.40.206 version (opcnetapi.com.dll & opcnetapi.dll) for client
With very fast exchange sometime the client cross the same item value with no chronological timestamp. 2 events comes in a short time.
First is True, second False value.
when issue occur we receive FALSE first and TRUE in 2rd. (not like real square signal).
is somebody observed this ?
Where to find the up-to-date Version Number for there Dll ?
where to find a releases notes for there Dll
.NET threading issues on the client side can result in out of order samples.
The version should be in the file properties dialog you can access from Windows Explorer.
