While the point determines basically the location of the data, parameters determine how the data will be accessed. Some operations do not need parameters (in such cases they still exist, but are empty), but most do. For example, a subscription typically has some kind of update rate as its parameter.

The parameters may depend on the type of point, and the operation involved. A typical connectivity that supports reading, writing and subscription will therefore have up to three types of parameters for each type of point: Read parameters, write parameters, and subscription parameters.

The parameters are not part of the point itself, and are therefore not selected with it in the Point Editor. They are part of the binding (in Live Binding Model) or data row definitions (in Connectivity Explorer tool).
