The following section details the generic MDISChokeObjectType structure and defines the properties associated with it. This is in general a vendor and operator independent description, but all users of the MDISChokeObjectType can add vendor specific data. The vendor specific data should be defined as part of a subtype of the MDISChokeObjectType defined in this document. It is assumed that the subsea system is the Server and host of the instance of the MDISChokeObjectType. The DCS based system is the Client in the system. It is assumed that all interactions with the instance of the MDISChokeObjectType are initiated by the Client and are directed to the Server.
