FRnet is an innovative industrial field bus that has many special features, such as high-speed deterministic I/O control, real I/O synchronization capabilities, non-protocol communication, and easy programming. If the user finds the complexity of Ethernet, CAN, Profibus or other field bus systems to be difficult, then they should love FRnet. FRnet products can be widely used, from low-end non-CPU I/O systems to high-end control systems, such as PC-based, PLCbased and PAC-based control systems.
