Introduction
Real time system is a system that produces instant output response within a specific amount of time without delay after receiving input signal. It has the advantages over the non-real time system because non real time systems do not produce immediate response and do not have accountability .Embedded communication network real time system is used in applications which require a set of synchronized data to be delivered in time and high response speed. Many field of application especially safety critical application use embedded communication network control to interact with real world due to flexible of designed system and less wiring complexity . Examples of safety critical application are military, robotics, medical, transportation system and avionics. Various types of communication control protocols which developed for network embedded real time system are used as a solution for communication problems.

us types of communication control protocols which developed for network embedded real time system are used as a solution for communication problems. Currently, robots are increasingly being integrated into working tasks to replace humans especially to perform the repetitive task. Besides, it might be difficulties to the worker whose must pick and place something that can affect itself. For example, things like chemistry that cannot be picked by human and for the military such as defuse bomb that needed robo the bomb to somewhere and for user that needed robot to do pick and place item while sitting and much more. Therefore a locomotion robot can be replaced human to do work. The development of FPGA controller is necessary to achieve higher performance on the robotic arm.

Mohamad Khairi Ishak , Ho Kar Hwai and Lee Kong Lam [1] communication is successfully developed at high data transfer for real-time control communication to communicate with other controller device for robotic arm with Arduino board and FPGA board via Ethernet. Through this implementation, the ability to communicate safety data directly over an Ethernet/IP network is achieved.

The purpose of this study is to develop the flexible and lightweight actuator and apply it into a flexible robot arm. In this paper, the master-slave attitude control and the trajectory control of the flexible robot arm are proposed. This robot arm has three degree-offreedom that is bending, expanding and contracting and will be applied into a rehabilitation device for human wrist. The master-slave control system which is proposed in this paper is necessary when a physical therapist wants to give a rehabilitation motion to a patient. While the trajectory control system is necessary when a sequential rehabilitation motion is applied to a patient. In this paper, an analytical model of a flexible robot arm is proposed for master-slave attitude control and trajectory control. Then, a compact and inexpensive control system is developed and tested. The system consists of a flexible robot arm, a low-cost embedded controller, accelerometers and small-sized quasi-servo valves which are developed by using the on/off control valve in our laboratory. The results from these experiments demonstrate that the master-slave attitude control can be realized by using an accelerometer and a simple analytical model of the robot arm. The trajectory control also was realized for a square trajectory by using an analytical model and a compact control system. The error between the desired trajectory and measured one is relatively large compared with typical robot arm. This is because by a friction that is existing in a rod-less type flexible pneumatic cylinder. The control performance can be improved by reducing the friction or by improving the control scheme.

In the monitoring system, the existing resource of Ethernet is used to remotely monitor power network parameters. A practical design of embedded Web server for power network monitoring is introduced, which applies high speed MCU (ARM7-LPC2148) to conveniently link to Ethernet. Adopting Ethernet interface control mode, the remote network monitoring of power network is realized under Windows. A web server in the device provides access to the user interface functions for the device through a device webpage. A web server can be embedded into any appliance and connected to the Internet so the appliance can be monitored and controlled from remote places through the browser in a desktop .The aim of the paper is to control the devices or equipment's from the remote place through a web page. The web-server circuit is connected to LAN or Internet. The client or a person on the PC is also connected to same LAN or Internet. By typing the IP-address of LAN on the web browser, the user gets a web page on screen; this page contains all the information about the status of the devices. The user can also control the devices interfaced to the web server by pressing a button provided in the web page.
In this system Ethernet communication is used to control the devices which are placed at the remote place by using LAN.
