What is MECHATROLINK communication?

What is MECHATROLINK communication?

MECHATROLINK-II—Defines protocol communication schemes through serial link equivalent to RS485 with a maximum speed of 10Mbit/s and maximum 30 slave nodes. MECHATROLINK-III—Defines protocol communication schemes over Ethernet with a maximum speed of 100Mbit/s and maximum 62 slave nodes.

What is MECHATROLINK III?

Print. This option is designed for connecting a drive to a field network using the MECHATROLINK protocol. The MECHATROLINK-III option allows the user to operate the drive, monitor the status, and change parameters from a MECHATROLINK master device at a communication speed up to 10Mbps.

What is the difference between Ethernet 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.

Is EtherCAT a Modbus?

EtherCAT uses a very simple data representation, sort of like Modbus. There is a data space, a huge data space, and each device is allocated a part of that data space. As messages are transmitted through the network, they map their portion of the data space to the data in the Ethernet message.

What is mechatrolink II?

NC MECHATROLINK-II is a powerful controller for point-to-point applications. It is based on MECHATROLINK-II Motion Bus, which reduces programming and development and maintenance costs. Supports PLC Open Function Blocks. Position control units with 2, 4 or 16 axes.

Why is EtherCAT so fast?

EtherCAT is significantly faster than shown, since several EtherCAT features were not taken into account: EtherCAT can use the same bandwidth for input and output data (full-duplex usage of the frame). EtherCAT can send the next frame before the first one has returned (pipelining of frames).

What is the difference between EtherCAT and Ethernet?

Ethernet, as stated previously, is able to route data through many different nodes, in a master/slave configuration, sending and receiving based on requests. With EtherCAT, the master sends data, possibly only a single frame for the entire node network that will pass through each node.

Who created EtherCAT?

Beckhoff
EtherCAT was developed by Beckhoff and present- ed for the first time at the 2003 Hanover Fair. The first EtherCAT products to be introduced by Beckhoff are EtherCAT terminals. The I/O, protection class IP 20, is based on the housing of the highly popular Beckhoff Bus Terminal system.
