A gauge hatch is provided that has a cover structure that incorporates a palletdiaphragm combination and that is cooperatively associated with a pressure responsive liquid seal subassembly. This facilitates development and implementation of devices within a device connectivity architecture based on the protocol, since the user has only to define the description of the device. An epistemological ground is set corresponding to the domain of the process and other components of the process are described for each epistemological ground. The head of the screw can therefore be seized in axially secure manner by a tool in the region of the shoulder, and this tool can then simultaneously transmit the necessary torque in the region of the tool drive as well. In an alternative embodiment the system includes an Application Programming Interface operable to configure andor control the one or more components for automatically allocating one or more resources. This structure enables detection of an electric signal from the stepped surface.
