System component having a configurable communication behavior, and method for operating such a system component
A system component having a configurable communication behavior. The system component includes at least one interface for a data bus for the communication with at least one further system component. A defined communications protocol for the transmitting and receiving of data and bus commands is used on the data bus. The communications protocol provides that the at least one further system component queries the communication behavior of the system component via the data bus to adapt its own communication behavior to that of the system component. The system component includes a register for configuration data that define the communication behavior of the system component on the data bus, the register being connected to the data bus so that the configuration data stored in the register are available on the data bus. The function scope of the system component allows for different communication behaviors.
Semiconductor device and information processing method
A semiconductor device capable of performing filter processing while suppressing an increase in processing time is provided. The semiconductor device includes a microcontroller. The microcontroller comprises a CPU, a memory and a CAN-controller. The memory stores software. The CPU executes the software stored in the memory. The CAN controller is configured to add label information to the message information. The CAN routing software stored in the memory implements a filtering function for performing a filter processing for determining whether or not to route the message information by using the label information.
EtherCAT Device
An EtherCAT device is disclosed. The EtherCAT device comprises a data input port to receive a signal representing data, the signal representing one of a plurality of possible logical values; and a degradation calculation circuit. The degradation calculation circuit is to read, demodulate, and convert the received signal into a digital domain representation; process the digital domain representation into slices, where the value of the received signal at a respective time is represented in a respective one of the slices; determine differences between the respective slices and reference slices; identify an intended logical value of the received signal responsive to the determined differences; determine a quantification of error at the respective time responsive to the identified logical value and the determined differences; and determine a signal quality index responsive to the determined quantification of error.
Method for operating an etherCAT fieldbus system, and etherCAT fieldbus 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.
Production system, communication method, and information storage medium
Provided is a production system including: a first industrial machine; and a second industrial machine configured to periodically communicate to and from the first industrial machine. The second industrial machine is configured to transmit its data to the first industrial machine through use of each of a plurality of periodic regions included in one period.
Vehicle multi-communication message type communication system
A vehicle communication system including a communication management unit (CMU) and a data gateway is provided. The CMU is at least in part configured to route first type messages using a first type message communication. The data gateway is configured to communicate second type messages to a remote location. The CMU is configured to route at least some of the first type messages to the data gateway. The data gateway is configured to communicate a pseudo acknowledgment for each message block of each first type message routed to the data gateway back to the CMU indicating the message block was received by a designated remote location. The data gateway is further configured to interface each received first type message into the second type message and communicate each second type message to the designated remote location using a second type of message communication.
ETHERCAT BUS SYSTEM INCLUDING AN ETHERCAT BUS MASTER AND ETHERCAT BUS STATION
An EtherCAT bus system includes an EtherCAT master, EtherCAT nodes, and an EtherCAT star hub arranged and/or assembled on the same printed circuit board with the EtherCAT master.
Responding to operator commands in a multi-homing Ethernet Virtual Private Network (EVPN)
Systems and methods for extending Ethernet Virtual Private Network (EVPN) protocols are provided. A Link Aggregation Group (LAG), according to one implementation, includes a plurality of Ethernet Segments (ESs) and a plurality of service ports configured to communicate over the plurality of ESs. The service ports are configured to enable an operator device to access an EVPN to receive Layer 2 (L2) and Layer 3 (L3) Ethernet services. Also, the service ports are configured to enable the operator device to operate with multi-homing functionality to receive the L2 and L3 Ethernet services via redundant paths associated with the plurality of ESs. The services ports are further configured to respond to operator commands, whereby the operator commands include one or more operator commands related to switching among the redundant paths.
Controller area network transceiver and controller
The disclosure relates to a controller area network, CAN, transceiver and a CAN controller. The CAN transceiver is configured to: compare a signal from the CAN bus with a negative threshold level; and provide a wake-up indication to the CAN controller based on the signal matching a predetermined pattern of one or more periods in which the signal is less than the negative threshold level. The CAN controller is configured to provide instructions to transmit a wake-up indication on the CAN bus.
