I create an item in the server
PsFloat1 := TPsFloat.Create(nil);

idx:= MyOPCProvider.AddressSpace.FindChild(RootIndex,’BIP’);
idx:= MyOPCProvider.AddressSpace.AddVariable(idx, PsFloat1, ‘BIP Pressure’);

But he is -1234566.09 in client browser. Why.

How to assign an empty value ?

That is a special value, PsVars.PsBadFloatValue, which is used as an initial value and whenever Quality is also BAD.

When you use the value, you should always check the quality first.
