Domains Configuration Panel

Explanation of the Domains Configuration Panel

Domains Configuration Panel

On the left of the Motorcortex-ECAT screen you will find the Domains Configuration Panel. In this panel you can configure the domains of your EtherCAT devices.

Ethercat devices have to be placed inside of Domains. A Domain is an group of EtherCAT slaves (physical cluster of EtherCAT modules). For your project you can make use of one single domain, or multiple domains. An advantage multiple domains, is that every domain is separate and can (if configured properly) be disconnected and reconnected (hot-plug), while other devices in other domains that remain connected are still operational. Beside hot-plug capability domains also keep your structure more clear.
