Hi,

 

We use OPC DA with a 1.30.3.0 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

 

Regards

.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.

Who supplied the assemblies?

If you have them but are not a member there must be a member who supplied them that is responsible for support.
