LE-Net (Loop Link)

LE-net is an original network of Fuji Electric. It is a link system between processors to conduct communication with other nodes connected to the LE-net.

Using the LE-net, broadcast communication and message communication can be conducted.

The LE-net can be connected either as a multi-drop network or a single loop REDUNDANT working network.

If the transmission line is broken, a transmission error occurs in a multi-drop network, but in a loop network, data communication between nodes can continue. This enables construction of a highly reliable system at a relatively low cost.

SX Network System

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.

Programmable Controllers (SPH)

Realizes High-Speed Advanced Machine Control

I/O control with a program capacity of up to 256K steps and up to 8192 points enables system configuration ranging from small through to large scale. 1ms program scan and I/O refresh are possible. Function and performance distribution are possible in multi-CPU system configuration with up to 8 CPUs.

Meets Increasing Demand for Higher Reliability

Compatible with CPU redundancy and power supply redundancy as standard functions. 1:1 warm standby or N:1 cold standby can be selected as required.

Open Network Oriented

Both the hardware and software conform to the IEC 61131 international standard for programmable controllers. Compatible with Ethernet, LonWorks, FL-net, DeviceNet, PROFIBUS-DP, AS-i, and other diverse open networks

Realizes Integrated Programming Support

Loaders for functional modules and POD, mainly loaders for programmable controllers realized on a personal computer, can be used in an integrated environment. Sharing of variable names (lables) required for each loader, and mutual data reference at the time of programming and debugging, can be performed easily.

Applicable to Software Control

Operates on a personal computer and panel controller, and the functions provide software equivalent to each hardware. Software PLC: Equivalent to the integrated controllers SPH
Software POD: Equivalent to the programmable operation display POD (TELLUS made of Hakko Electronics Co., Ltd) The SX Communication Middleware enables coordination with comercial SCADA software.

Remote Monitoring, Maintenance Support, and Preventive Maintenance Using IT

On-site information can be obtained in optimal ways such as monitoring by the Web Browser via the Internet or intranets, E-mail transmission when an error occurs, and remote operation using support tools to realize labor savings, planned maintenance, and more swift maintenance service.
