Further examples, Fig. 11, relate to a computer program PRG, comprising instructions which, when executed by the program PRG by a computer 12, cause the computer 12 to execute the method according to the embodiments. Further examples, Fig. 7, relate to a data carrier signal DCS, which characterizes and / or transmits the computer program PRG according to the embodiments. The data carrier signal DCS is transmittable, for example, via an optional data interface (not shown) of the device 10, and / or via the data line 20-DL. Further examples, Fig. 8,relate to a product, for example a module, for example a Connect module, CM, for a locking system VS for a door T or a window F, comprising at least one device 10 according to the disclosure. The module CM can, for example, communicate with a device 20 or with several devices 20, 20' via the data line 20-DL, for example using a master-slave principle, in which, for example, the module CM or the device 10 at least temporarily assumes the role of the master and the (further) device 20, 20' at least temporarily assumes the role of the slave. For example, the further device 20' is also an opener for a door T or a window F. Further examples, Fig. 1, 10, relate to a device 20 for a locking system VS for a door T or a window F, wherein the device 20 has a data line 20-DL for exchanging information INF by means of, for example, a serial bus system.wherein the device 20 is configured for: exchanging 350 (Fig. 9, e.g., receiving 350a and / or transmitting 350b) information INF with a device 10, for example, a device 10 according to the disclosure, and / or with a module CM, for example, a module according to the disclosure, via the data line 20-DL in a first time range ZB1, receiving 352 electrical energy EE via the data line 20-DL, for example, for supplying at least one component 22 of the device 20, in a second time range ZB, which lies at least partially outside the first time range ZB1. In some examples, Fig. 9, the device 20 is configured to buffer the electrical energy EE received via the data line, for example, to temporarily store it 354, for example by means of a local storage device 22, for example, configured as a capacitor, for example, an electrolytic capacitor or double-layer capacitor. In some examples, Fig. 10,The device 20 has a memory device 22, wherein, for example, the memory device 22 is connected to the data line by means of at least one diode 23. In some examples, this can prevent the memory device 22 from delivering electrical energy to the data line 20-DL, for example when the data line 20-DL, e.g., as part of an information exchange via the data line 20-DL, is brought to a potential (e.g., ground potential) that is lower than a potential corresponding to a current charge state of the memory device 22. In some examples, Fig. 10, the device 20 has a transceiver device 24 for the serial bus system. For example, the memory device 22 can be used to supply electrical energy to the transceiver device 24. For example, the memory device 22 can be used to supply electrical energy to at least one, for example, electromotive and / or electromagnetic,actuator 26, M of the device 20. In some examples, element 26 symbolizes, for example, a power driver stage for an electric motor M. In some examples, the electric motor M is preferably, for example exclusively, controlled in those time ranges ZB2 in which an electrical energy supply EE of the device 20 is provided via the data line 20-DL, but, for example, no information exchange takes place. Optionally, the device 20 has a local control device 28 for this purpose, which can also be supplied, for example, at least temporarily, by the memory device 22. Fig. 12 schematically shows a simplified block diagram of a device according to some examples. Element E1 symbolizes a module, for example, connect module, see also element CM of Fig. 8. Element E2 symbolizes a computing device,for example, a microcontroller. Element E3 symbolizes a LIN transceiver device. Element E4 symbolizes a semiconductor switch for selectively connecting or disconnecting a line E5a connected to the LIN data line 20-DL to a first reference potential E5, wherein the selective connection or disconnection is carried out, for example, based on a control signal E7 from the microcontroller E2. E6 symbolizes a second reference potential, for example, ground potential. E8, E9 each symbolize UART connections, e.g., E8 as "UART1" and E9 as "UART2" of the microcontroller E2, for connection to the LIN transceiver device E3. For example, the microcontroller E2 can perform an information exchange according to the LIN bus system via UART1 E8 using a first channel E10 of the LIN transceiver device E3.e.g., with the device 20 (Fig. 1). For example, the microcontroller E2 can carry out an information exchange according to the LIN bus system via the LIN data line 20-DL, e.g., with the device 20 (Fig. 1), via UART2 E9 using a second channel E11 of the LIN transceiver device E3. In some examples, UART2 and the second LIN channel E11 are used to check whether the module E1 is connected to a device 20 via two lines (e.g., data line 20-DL (for at least temporary electrical power supply and / or data communication) and ground line) or, e.g., via three lines (e.g., data line 20-DL, e.g., exclusively for data communication, and two lines for operating voltage potential and ground potential (for the electrical power supply)). In some examples, the module E1 can, for example, send a message via the first LIN channel E10, while, e.g., a connection is maintained between the lines E5a,E5 is separated by element E4. In this case, if the message is received via the second LIN channel E11, the module E1 or the microcontroller E2 can, in some examples, conclude that the device 20 is connected to the module E1 via two lines (i.e., not via three lines). In some examples, the module E1 and the device 20 can, for example, be put into a two-line mode, e.g., a 2-wire connection, upon detection of the connection via two lines (the microcontroller, for example, directly itself, based on the detection, and the device 20, for example, by the microcontroller E1, for example, by means of a control command via the data line 20-DL). In some examples, the module E1 and / or the device 20 can be reset, e.g., via a respective reset button (not shown). Further examples, Fig. 14,relate to a use 400 of the method according to the disclosure and / or the device 10 according to the disclosure and / or the module CM according to the disclosure and / or the device 20 according to the disclosure and / or the computer-readable storage medium SM according to the disclosure and / or the computer program PRG according to the disclosure and / or the data carrier signal DCS according to the disclosure for at least one of the following elements: a) exchanging 401 information INF and electrical energy EE with the device 20 via the data line 20-DL, for example in time-division multiplexing, b) at least temporarily using 402 the data line 20-DL for an electrical energy supply EE of the device 20, c) reducing 403 a number of connecting lines to the device 20, d) increasing 404 flexibility regarding the operation of the device, e) avoiding 405 structural measures, for example retrofitting one or more lines to the device,f) Determining 406 a connection type, for example, a connection type, with respect to the device 20. In some examples, the principle according to the disclosure enables, for example, an efficient retrofitting or provision of at least one device 20, for example in existing structures, for example, existing buildings, which, for example, provide a maximum of two lines for connecting a device 10 to a device 20, for example, for implementing the data line 20-DL and an optional ground line 20-GND. In some examples, data communication via the data line 20-DL can be carried out, for example, completely deterministically, since the knowledge required for this is present, for example, in the module E1. In some examples, Fig. 8, the principle according to the disclosure can also be used with multiple devices, e.g., multiple bus participants, e.g., LIN bus participants, 20.20'. In some examples, a voltage level for the first reference potential BP1 can, for example, be equal to a HIGH level for an information exchange via the data line 20-DL, e.g., in a range of, for example, approximately 5 volts to 24 volts. In some examples, a voltage level for the first reference potential BP1 can, for example, be greater than a HIGH level for an information exchange via the data line 20-DL. For example, the first reference potential can be 24 volts, and a voltage level of 5 volts or 10 volts can be used as the HIGH level for an information exchange via the data line 20-DL, etc. In some examples, the semiconductor switch HLS (Fig. 4) is designed as a logic level MOSFET, so that its control electrode HLS-SE, for example, the gate electrode, can be controlled directly, e.g., by a microcontroller E2 (Fig. 12).See connection E7. In some examples, currents of several amperes can be provided for the electrical power supply EE via the data line 20-DL, for example, at least temporarily, so that, for example, electromotive and / or electromagnetic actuators 26, M with comparatively high electrical power can also be reliably supplied via the data line 20-DL, for example, in comparison to, for example, a temporary pure information transmission via the data line 20-DL. In some examples, for example when using an information exchange according to the LIN standard, the data line 20-DL can be pulled to a HIGH level for LIN communication, for example via a pull-up resistor (not shown), and a transmission of information by a component 10,20 is achieved, for example, by repeatedly applying ground potential to the data line 20-DL according to the LIN protocol. In some examples, the semiconductor switch HLS (Fig. 4) is advantageously high-impedance.
