The Yokogawa F3LX02-1N is an interface module for Yokogawa’s FA-M3 (or FA-M3R) controller family. It provides connectivity to the FL-net (OPCN-2) open field automation network standard. This module enables programmable controllers, robot controllers, CNC machines, and other FA devices to be networked together for high-speed, deterministic data exchange. Features include support for cyclic and message (event-based) transmission, a large number of link points, and the use of Yokogawa’s proprietary RRR (“Rapid Refresh and Reflection”) technology to reduce communication latency.
