Build Your EtherCAT Motion Control

NexECM is an EtherCAT master communication software that fully complies with EtherCAT communication protocols, including the data link layer and application layer.

The figure below shows the comparison of the common communication protocols (such as HTTP, TCP/UDP, and IP) and the EtherCAT communication protocol in the OSI network model. The EtherCAT communication protocol in the OSI model mainly defines two layers: data link layer and application layer. The EtherCAT communication protocol used Ethernet in a physical layer so that we can use a general Ethernet cable to connect the network.

The comparison of EtherCAT and TCP/IP OSI network architecture

By using NexECM, you can easily communicate with EtherCAT slave modules such as EtherCAT servo drivers and EtherCAT I/O modules.

You can develop your own EtherCAT motion control functions under the real-time system, or you can develop the EtherCAT related application process under the Microsoft® Windows.
