Described is also a CAN communication protocol system for an internal combustion engine for exchanging fuel consumption-optimizing and/or operating fluid consumption-optimizing and noise-optimizing messages between drive components and output components, which also help to increase the overall availability of the system.

An EtherCAT fieldbus system has an EtherCAT master and a number of EtherCAT slaves. The EtherCAT master and the number of EtherCAT slaves are coupled together by an EtherCAT fieldbus in order to exchange data. A method ascertains active EtherCAT slaves by way of the EtherCAT master; requests respective product codes of the active EtherCAT slaves by way of the master; ascertains a respective device identification of the active EtherCAT slaves from the respective product codes by way of the EtherCAT master, and switches the state of the EtherCAT fieldbus system into the operational state by way of the EtherCAT master if the respective device identification of the active EtherCAT slaves matches a specified device identification.

A method for deterministic auto-configuration of a device upon connection to an apparatus includes as a first step, during a first-time connection of the device to the apparatus, a generation of a device-specific configuration data structure, wherein this configuration data structure identifies the configuration data of the device and/or the apparatus, which configuration data was determined during a first-time connection of the device to the apparatus. The next step is storing of the configuration data structure in the device and/or in the apparatus. During a renewed connection of the device to the apparatus, the first-time configuration data of the device and/or the apparatus is determined by means of the configuration data structure, and the device and/or the apparatus correspondingly furnishes the first-time configuration data. The system is equipped in such a way as to execute the stated method.

Methods, systems, and devices manipulate operation of at least one electronic control unit (ECU) connected to a controller area network (CAN) bus. The at least one ECU includes at least one error counter, by counting errors associated with at least one ECU. The manipulating is based on generating and broadcasting via the CAN at least one bit stream destined to at least one ECU, thereby manipulating at least one ECU status, determined by the ECU error counter and querying for its status state.

An array controlling system includes a database, a controlling center and an array device. The controlling center reads a plurality of data of the database. The array device includes a processing unit, a main bus and an array unit. The processing unit receives a command of the controlling center and converts the command into a communication data. The main bus is configured to transmit the communication data to the array unit. A plurality of array modules of the array unit are connected in series with each other through a serial bus, and sequentially receive the communication data. The processing unit controls each of the array modules according to the communication data. A plurality of sensing data of the array modules are collected to the processing unit.
