In a method for operating a production machine or machine tool, an app having at least one virtual container and an app configuration is downloaded from a remote memory store into a memory store of the machine, and an immediate start of the downloaded app on the production machine or machine tool is automatically prevented. The app configuration of the downloaded app is then automatically modified, and identifiers included in the app configuration are automatically evaluated and compared with identifiers included in a positive list or in a positive list and a negative list. An identifier which is not contained in the positive list, or an identifier which is contained in neither the positive list nor in the negative list is automatically replaced with an automatically selected or automatically generated target expression; and the downloaded app following the modification of the app configuration is then automatically started.

The present disclosure relates to a method for operating a measuring transducer of process automation technology, comprising at least the following steps: starting the measuring transducer by starting its operating system, wherein the operating system provides at least one interface; starting at least one interpreter, wherein the interpreter accesses the interface; and executing an extension in the interpreter. The present disclosure further relates to a measuring transducer for implementing the method.

According to one embodiment, an information processing apparatus is used with a network including one or more units each includes a sensor and/or actuator. The information processing apparatus is configured to use one or more computer programs (written in programming languages such as JAVASCRIPT and JAVA) each for controlling the sensor and/or actuator of the connected units. A library (default library/user-defined library) is prepared. The library includes classes each describing a method to control the sensor and/or actuator of the one or more units. The computer program can be created by combining one or more classes obtained from the library. The information processing apparatus is configured to control the sensor and/or actuator according to the created computer program.
