1 Abstract—Advanced industrial automation system can be monitored and controlled by real time situation is more useful than other formal systems in the sector of industrial life. Distributed Control System (DCS) is more popular than any other control systems in the modern industrial processes. This research leads to “Real Time Graphical User Interface Monitoring System” for Micro-Factory. The current research project is based on the construction of DCS based Micro-factory. The Industrial Local Area Network (LAN) is built between the server for the operator and the clients for the two robots control and only one CNC milling machine. The client- server model is more suitable for this research. The existing DCS can be divided into two sections: the first one is cheap and inflexible control and the second one is expensive but it is flexible control system. This research leads to cheap and flexible distributed control system. In this research, the simulation of the whole process is described in real- time condition by using Visual Basic.Net programming under Visual Studio 2005 software. The parallel ports of Client computers and the controllers have been communicated with parallel port interface VB.Net program. Index Terms— DCS, Micro-factory, Visual Studio.Net, Control System. I. INTRODUCTION The evolution of plant automation systems, from very primitive forms up to the contemporary complex architectures, has closely followed the progress in instrumentation and computer technology that, in turn, has given the impetus to the vendor to update the system concepts in order to meet the user’s growing requirements. This has directly encouraged users to enlarge the automation objectives in the field and to embed them into the board objectives of the process, production, and enterprise level. The integrated automation concept [1] has been created to encompass all the automation functions of the company. This was viewed as an opportunity to optimally solve some interrelated problems such as the efficient utilization of resources, production profitability, product quality, human safety, and environmental demands.

Effective control of such systems can only be made feasible using adequately organized, complex, large-scale automation systems like the distributed computer control systems [2]. It is a software application specially designed to work on client computers in the production control, providing communication with the devices (independent controllers, programmable robotics, etc) and controlling the process from the server computer. In this system, a server computer supervised and managed the data, as well as data processing and process control. One or two operators can control the whole system from the server or client computers instead of many workers for large industrial automation systems. In addition, this system implementations have migrated from custom hardware and software to standard hardware and software platforms. These changes have led to reduced development, operational, and maintenance costs as well as providing executive management with real-time information that can be used to support planning, supervision, and decision making. This research implements vehicle spare parts manufacturing plant for industrial automation, and this can also be used other industrial automation systems. It includes how DCS systems use in the industrial automation. It applied to interface sever protocol needed between the DCS software and the hardware process. It is applied to dc motor drivers, sensing drivers, Programmable Interface Controller (PIC) microcontroller device and parallel port communication. II. RESEARCH DIRECTION Format For the “Network Systems” portion, the client- server model has to be studied. To communicate client computer and server computer, the RJ45 and the Ethernet switch should be applied. So the various types and specifications of Ethernet switch will be studied. For the communication between the client computer and the server computer, the JAVA programming language will be studied because the client program and the server program can be applied to the JAVA programming language. For the “Real Time Graphical User Interface Monitoring System “ portion, the Visual Basic.Net programming Language under Visual Studio 2005 Software has to be studied. For the “Agent Based Distributed Control” portion, the JAVA programming Language has been applied to Distributed Control System for Micro-Factory Using Visual Studio.
