I have an OPC Client issue.
I have an OPC Server which belongs to my firm which is a 3.0 version. I installed the DSC Module and use the Labview OPC Client.
Labview manages to read all my I/O from my robot. I can create related linked variables, then i attached an indicator to them.
When i deploy my Vi everything goes well, I have no error message but when I force one of my robot variables, Labview doesn't show me the changing value. The value keep at 0 and never changes. No matter the loop time value is.
I tried the same things with Softing OPC Client (free soft). Softing manages to read all my I/O from my robot. When i force a value, i can read it directly on Softing OPC Client software. I presume there is no problem in my adresses and connection. I believe the problem comes from Labview configuration but i don't know what.
Someone already experienced that ? Any idea about my issue ?

Deadband option is only available for double or single. The probable reason is that deadband works with percentage, what is not really logic with an integer.
Which kind of data do you use ?

I have to use boolean and integer. When i convert integer to double, i can set up a deadband option but the value doesn't refresh. I tried all support i could find in ni.com website. The Labview OPC Client still doesn't work.
The strange thing is that it is working fine with another OPC Client...
Any news idea ?
