5.2.1 FL-net
overview
(1) FL-net concept
The FL-net is an Ethernet-based factory-automation control network. It has a cyclic
transmission function and message transmission function.
The basic ideas incorporated in the FL-net are as follows:
• Ethernet is used as the media (physical level, data link) of communication between FA
(factory automation) controllers.
• UDP/IP prevalent throughout Ethernet is used to implement a basic means of data
transmission.
• Transmission over a predetermined period of time is assured by managing/controlling
communication media access of networked nodes (for collision avoidance) while making use
of the above-mentioned basic means of data transmission.
The FL-net is designed for use in an FA (factory automation) control network that provides data
exchanges between programmable controllers (PLCs), robot controllers (RCs), computer
numerical control (CNC) devices, and various other production system controllers and control
personal computers.
Figure 5-8 shows the role of the FL-net.
