SDL stands for "Smart Display Link". SDL allows all communication between the Automation Panel and a B&R Industrial PC to be handled using a single cable. In addition to display data, it also transmits touch screen, matrix key, LED and service data. The Automation Panel can be installed up to 40 m from the B&R Industrial PC. USB 1.1 is fully integrated in SDL and transferred over this distance as well without the need for external modules. A panel can be operated on a line using an SDL receiver.
