While the most information needed to perform OPC tasks is contained in arguments to method calls, there are some component-wide parameters that are not worth repeating in every method call, and also some that have wider effect that influences more than just a single method call. You can obtain and modify these parameters through properties on the EasyAEClient object.

Following are instance properties, i.e. if you have created multiple EasyAEClient object, each will have its own copy of them:

Instance properties can be modified from your code.

In QuickOPC.NET, if you have placed the EasyAEClient object on the designer surface, the instance properties can also be directly edited in the Properties window in Visual Studio.

In QuickOPC-COM, your code can set different values to these properties if needed.

 

Following properties are static, i.e. shared among all instances of EasyAEClient object:

Static properties can only be modified from your code.

Please use the Reference documentation for details on meaning of various properties and their use.
