An MTP includes the following information:
- Description of the data objects
- Description of the control image
- In the future: Description of services, etc.
This description file can be read in and processed by higher-level systems, such as visualization or process control systems, called “Process Orchestration Layer” (POL) in the following. Given is basic intention and functionality, MTP can be accurately compared to a printer driver. The driver, too, has the goal of connecting subsystems − in this case, a printer – to a central computer, regardless of manufacturer. Connect, switch on – print. Or, in the jargon of factory automation and process technology, “Plug and Produce.”
