Problems solved by technology

However, such manual installation of terminating resistor connectors may be complicated depending on the installation environment and installation location, and there is also a risk of forgetting the termination due to careless installation
Furthermore, there is the problem that, e.g. in energy storage, there is no standard construction of suitable terminal connectors for the bus interface

Embodiment Construction

[0038] Such as figure 1 As shown, the bus-compatible devices (also other bus-compatible devices 2 and 3 in FIG. 2 ) each comprise an input interface 5 and an output interface 6, which can be configured, for example, in the form of a plug and can be inserted or connected to a serial port separately. Bus (especially CAN bus) 16 .

[0039] Here, the input interface 5 and the output interface 6 both include two signal line terminals 7 and 8, so as to be connected to the two signal lines of the serial bus 16, especially to its CAN high line and CAN low line in the form of a CAN bus. Wire.

[0040] In addition to the two signal line terminals 7 and 8, each of the input interface 5 and the output interface 6 also includes a supply voltage terminal 9 for supplying a supply voltage to the interface of the corresponding next device and can be used to extract or receive the next A feedback terminal 10 of the supply voltage supplied by the device. Advantageously, the power supply termi...

Abstract

The invention relates to a bus-capable device having an input interface and an output interface for connecting to a serial bus, particularly a CAN bus, wherein the input interface and the output interface each have at least one signal line connection, and further having a terminating resistor for terminating the bus and a switch apparatus for switching the terminating resistor active as a function of the connection status of the input and output interfaces, wherein the input interface and the output interface each having a supply voltage connection for providing a supply voltage to the output and / or input interfaces of a respective next bus-capable device and a feedback connection for receiving the supply voltage from an output and / or input interface of a respective next bus-capable device, wherein the switch apparatus has an evaluation circuit for determining the presence of the supply voltage at the feedback connections of the input and output interfaces and an activation circuit for switching the terminating resistor active when the supply voltage is found by the evaluation circuit to be absent from the feedback connection of the input interface and / or from the feedback connection of the output interface.

Description

technical field [0001] The invention generally relates to the termination of bus systems by means of switchable terminating resistors. Here, on the one hand, the invention relates to a bus-compatible device comprising an input interface and an output interface for connection to a serial bus system, in particular a CAN bus with a five-pin M12 plug connector, wherein the input interface Each of the and output connections has at least one signal line terminal and also has a terminating resistor for terminating the bus system and a switching device for activating the terminating resistor depending on the connection state of the input and output connections. In this case, the invention also relates to a device arrangement with a plurality of such bus-compatible devices, which are connected via their input and output interfaces to the serial bus. In another aspect, the invention also relates to an energy store in which a plurality of the bus-compatible devices described above are i...
