Is EtherCAT same as Ethernet?
Is EtherCAT same as Ethernet?
EtherCAT and EtherNet/IP are both Ethernet application layer protocols designed to move inputs and outputs between controllers and endpoints on a manufacturing machine. That sounds like they are similar; however, though the result may be similar, how they accomplish moving I/O data couldn’t be more different.
What is the difference between Ethernet IP and EtherCAT?
Like EtherNet/IP, EtherCAT is built on the Ethernet physical layer. But instead of using TCP/IP for transport and routing of messages, EtherCAT uses a “processing-on-the-fly” (also referred to as “communicating-on-the-fly”) approach.
What is Ethernet over EtherCAT?
Ethernet over EtherCAT (EoE) transparently tunnels standard Ethernet communication via EtherCAT. Tunneling allows the master device to optimize Ethernet communication without affecting the process data communication. EoE enables communication with network devices.
CANopen over EtherCAT?
CANopen over EtherCAT features PDOs and SDOs as well as an Object Dictionary, the CANopen state machine and fully supports all CANopen device profiles. It is shown that EtherCAT provides a smooth migration path for CANopen devices towards the brave new world of Industrial Ethernet.
Can I open over Ethernet?
One of the increasingly popular Ethernet based open standards is Ethernet Powerlink or CANopen over Ethernet. Originally a proprietary standard developed by Bernecker and Rainer, it combines the low cost and convenience of Ethernet hardware, with software suitable for real time automation control.
Can over EtherCAT protocol?
The CANopen over EtherCAT (CoE) protocol enables the complete CANopen profile family to be utilized via EtherCAT. The SDO protocol is used directly, so that existing CANopen stacks can be used practically unchanged.
What is the maximum transmission range for EtherCAT?
Up to 65,535 devices can be connected to EtherCAT, so network expansion is virtually unlimited. For the physical layer within a modular device, such as a sliced I/O station, EtherCAT also defines an LVDS-based transmission (Low Voltage Differential Signaling).
