An instance of this function block type encapsulates an instance of the ZONE_VIEW type and the local multicast service interfaces necessary for inter-layer communication with the View layer of the MVCD framework.

See the VAV_VIEWL configuration for examples of the use of instances of this type.

For convenience, the names of the local multicast channels used by an instance of this type with an instance name denoted by <name> will have the default values shown below. These values can be overridden by connection to a non-default variable or configuration parameter.
