B&R 7EX484 Ethernet POWERLINK Bus Controller Module

The B&R 7EX484 is an Ethernet POWERLINK bus controller module developed for the B&R System 2003 automation platform. It acts as the central network manager, establishing real-time industrial Ethernet communication to coordinate servo drives, I/O modules and other field nodes within the automation system.

Equipped with four independent POWERLINK communication ports, this module supports flexible network topologies for synchronous motion control. Featuring robust industrial hardware design and built-in diagnostic LEDs, it delivers stable deterministic data transmission and is widely used for machine retrofitting and spare part replacement.
