A method and a device for the computer-assisted simulation of a modular technical system, wherein for each real module of the modular technical system, a corresponding virtual module is generated, is provided. The virtual module includes a controller for controlling a module-specific process and at least one module-specific simulation model, to which model type information is assigned, for simulating the model-specific process. The virtual module is designed to simulate the module-specific process that is controlled by the controller by means of the module-specific simulation model and/or the controller of the real module, and is provided for a computer-assisted simulation of the modular technical system as a data container. In particular, the following allows a virtual start-up of modular process systems.

In a method for the encryption communication in a process plant, one or more keys for coding of electronic signals regarding the process plant, such as actuation signals, measurement signals, state signals, warning signals or such, are provided. The one or more keys are transmitted as acoustic signal via a ductwork guiding plant fluid, particularly a process fluid or an auxiliary fluid, from the first communication partner to the second communication partner. The process plant can be a chemical plant, a power plant, or a food-processing plant. The communication can be between a first and a second communication partner, which can include at least one field device, such as an actuator for adjusting a process fluid and/or a control electronics for supervising, controlling and/or regulating processes of the process plant.
