A method for configuration of a production plant set up for carrying out at least one chemical reaction, wherein the production plant comprises at least one plant module (4x, 4y), and, for configuration of the production plant, the plant module (4x, 4y) is selected from a module database running on a first server system and is compiled from a component database running on the first server system, or the plant module (4x, 4y) is selected from a module database running on a first server system and is compiled from a component database running on a second server system; characterised in that the selection or compilation of the plant module (4x, 4y) comprises the following steps: - manual first input of process-specific technical requirements for the plant module (4x, 4y) in a query mask of the module database and confirmation of the input; - comparing the first input with at least one technical parameter, stored in the module database and defining a process-specific property of a respective plant module, of a plurality of plant modules on the first server system, for determining whether a plant module is available in the module database which fulfils the process-specific technical requirements for the plant module (4x, 4y) for configuration of the production plant, and if the result is negative: (i) designating at least one plant module whose process-specific property does not fulfil the process-specific technical requirements in an output mask of the module database; (ii) identifying at least one module component of the designated plant module which does not fulfil the requirements for the plant module (4x, 4y) and/or of a technical parameter of a series component of the module component of the designated plant module which does not fulfil the requirements for the plant module (4x, 4y); - manual or automatic second input of process-specific technical requirements for the identified module component and/or the technical parameter of the series component into a query mask of the component database; - comparing the second input with at least one technical parameter of a plurality of series components stored in the component database and defining a process-specific property of a respective series component, and if the result is positive: (a) designating at least one series component of a module component which fulfils the process-specific technical requirements in an output mask of the component database and compiling the output plant module with the output series component. - manual first input of process-specific technical requirements for the plant module (4x, 4y) in a query mask of the module database and confirmation of the input; - comparing the first input with at least one technical parameter, stored in the module database and defining a process-specific property of a respective plant module, of a plurality of plant modules on the first server system, for determining whether a plant module is available in the module database which fulfils the process-specific technical requirements for the plant module (4x, 4y) for configuration of the production plant, and if the result is negative: (i) designating at least one plant module whose process-specific property does not fulfil the process-specific technical requirements in an output mask of the module database; (ii) identifying at least one module component of the designated plant module which does not fulfil the requirements for the plant module (4x, 4y) and/or of a technical parameter of a series component of the module component of the designated plant module which does not fulfil the requirements for the plant module (4x, 4y); (i) designating at least one plant module whose process-specific property does not fulfil the process-specific technical requirements in an output mask of the module database; (ii) identifying at least one module component of the designated plant module which does not fulfil the requirements for the plant module (4x, 4y) and/or of a technical parameter of a series component of the module component of the designated plant module which does not fulfil the requirements for the plant module (4x, 4y); - manual or automatic second input of process-specific technical requirements for the identified module component and/or the technical parameter of the series component into a query mask of the component database; - comparing the second input with at least one technical parameter of a plurality of series components stored in the component database and defining a process-specific property of a respective series component, and if the result is positive: (a) designating at least one series component of a module component which fulfils the process-specific technical requirements in an output mask of the component database and compiling the output plant module with the output series component. (a) designating at least one series component of a module component which fulfils the process-specific technical requirements in an output mask of the component database and compiling the output plant module with the output series component.
