LonWorks
Internationally noticeable open network for building management. System configuration as a device with distributed autonomous functions is enabled by the control functions incorporated in site devices. Replacement, update, addition, and removal of site devices can easily be performed.
FL-net (OPCN-2)
Open network at the FA application type controller level established by the Manufacturing Science and Technology Centrer and the Japan FA Open Systems Promotion Group. Allows inter-connection with PC, CNC, and robots beyond the frame of a signle manufacturer. The communication physical layer employs Ethernet.
PROFIBUS-DP
Device level open network established by the EN 50170 suits time-critical applications between an automation system and distributed devices (remote I/Os, iverters, etc.)
OPCN-1
Device-level open network established by Japan Electrical Manufacturers Association. Allows connection with PC and robots using the same signal line beyond the frame of a single manufacturer, very effective in open system improvement and optimization.
DeviceNet
Open device-level network which facilitates inter-connection of control equipment such as PCs, personal computers, sensors, and actuators. Wiring cost reduction by minimizing wiring, and multi-vendor equipment connection simplify and economical system configuration.
AS-I
Bit-level network optimum to distribution of the I/O equipment including proximity switches, photoelectric switches, pushbuttons, and intelligent equipment such as ultrasonic sensors.
