What protocol does EtherCAT use?
IEEE-802.3
The EtherCAT protocol is maintained by the EtherCAT Technology Group and is standardized under IEC 61158….
| Ethernet | EtherCAT | |
|---|---|---|
| Common Physical and Data Link Layers | Yes | Yes |
| International Standard | IEEE-802.3 | IEC 61158 |
| Deterministic Timing | No | Yes |
| Master/Slave Operation | No | Yes |
What is EtherCAT module?
The EtherCAT module is based on Beckhoff´s EtherCAT technology and contains all protocol functions including the CANopen based application layer for process data (PDO) and parameter data (SDO) communication functions. The module provides a 2-port 100 Mbit/s interface with standard RJ45 connectors.
What is EtherCAT interface?
EtherCAT is a real-time Industrial Ethernet technology originally developed by Beckhoff Automation. The EtherCAT protocol which is disclosed in the IEC standard IEC61158 is suitable for hard and soft real-time requirements in automation technology, in test and measurement and many other applications.
What is EtherCAT automation protocol?
The EtherCAT Automation Protocol (EAP) specifies communication services and protocols for Master devices and Ethernet-based devices connected with a standard Ethernet network. These networks are used for example to connect machine parts or separate machines within plant automation.
Is EtherCAT real time?
EtherCAT is a real time and flexible Ethernet protocol that was published as IEC 61158 standard. Real time EtherCAT data exchange follows a “processing on the fly” principal. Meaning that, all data passes through each slave device with minimal delay prior to processing.
What is EtherCAT cycle time?
EtherCAT® communication is based on a cyclic execution of tasks starting from the EtherCAT host with a constant Eth- erCAT telegram repeat rate. The constant repeat rate is known as the cycle time. For majority of the applications, a cycle time longer than 500 µs is sufficient.
What is EtherCAT IP?
The EtherCAT IP core enables the EtherCAT communication function and application-specific functions to be implemented on an FPGA (Field Programmable Gate Array – i.e. a device containing programmable logical components). The EtherCAT functionality is freely configurable.
Is EtherCAT full duplex?
Using full-duplex Ethernet physical layers, the EtherCAT slave controllers close an open port automatically and return the Ethernet frame if no downstream device is detected. Slave devices may have one, two, or more ports.
Is EtherCAT real-time?
What is Ethernet over EtherCAT?
”The communication protocol “Ethernet over EtherCAT” (EoE) is used to transfer process data as well as standard Ethernet communication. EoE is used, for example, to access the web server of an EtherCAT slave from an engineering PC. The Ethernet communication is tunneled through EtherCAT.
