This five-part training provides a comprehensive introduction to commonly used interfaces (RS-485, RS-422, ProfiBus, RS-232, IO-Link, CAN and LIN). This 4th video introduces RS-232 and IO-Link with standard overviews and portfolio highlights. Learn about the TIDA-00540, a reference design that allows for communication over RS-485 or RS-232 data buses without requiring separate wiring for each and understand IO-Link, the first standardized I/O communication for sensors and actuators.
