Suitability of Ethernet for Motion Control

From Galil Motion Control

This application note explains why TCP/IP over Ethernet is often the best choice for multi-axis motion control. Appendix A details the differences between three popular serial protocols; TCP/IP, a typical Fieldbus network, and simple RS-232.

The Assurance of Good Data Systems engineers often need to select the appropriate network for optimum performance of their motion control system. Quite often, the two competing protocols are TCP/IP over Ethernet or a Fieldbus architecture. Examples of Fieldbus systems include CanOPEN, SERCOS, or DeviceNet.

CNC Controllers
CNC controllers are used to control machines and processes. They provide capabilities ranging from simple point-to-point linear control to highly complex algorithms with multiple axes of control. CNC controllers are used to retrofit many types of machine shop equipment.
Machine Controllers and Monitors
Machine controllers and monitors use electronic numeric control and monitoring interfaces for programming and calibrating computerized machinery.
Motion Controllers
Motion controllers range from simple linear controllers to complex, user-programmable modules that act as controllers within complex integrated multi-axis motion systems.
