Module for a technical installation and system and method for carrying out a technical process

A system for the execution of a process by means of a technical facility comprising:

• a. a plurality of modules comprising:
• i. a technical hardware for the execution of a technical sub-process;
• ii. a control for a local control of the technical hardware, wherein the control is adapted to control the technical hardware independently;
• and
• iii. an external interface of the control;
• wherein the external interface comprises an administration shell, wherein the administration shell publishes at least one service relating to an output product of the module via a network;
• and
• iv. wherein the external interface is adapted to request at least one service relating to an input product of the module via the network;
• wherein the plurality of modules can execute sub-processes of the technical process;
• b. a request module, comprising:
• an external interface including its own administration shell;
• and
• c. a network which connects the plurality of modules and the request module with each other;
• wherein:
• d. the request module can request a service for an end-product at the modules via the network;
• wherein the request module further comprises an own state machine;
• wherein in a first state of the own state machine:
• I. the request module requests a service for an end-product at the modules via the network;
• II. a first module, that offers the service for the end-product, requests at least one service for its input product at the other modules via the network;
• III. a second module, that offers the at least one service for the input product of the first module as an output product, requests at least one service for its input product at the modules via the network;
• and
• IV:
• the request module receives a message that the process is complete from one of the modules;
• and
• wherein the own state machine of the request module transitions into a second state when the process is complete, wherein in the second state the process can be started.
