Nowadays, the world is searching for new technologies or new methods to make the controlling process more automated or easier to access. This search has widely increased to reach such technology starting from HART technology and passing through Asset Management system (AMS). So developing such technology will open the field for another technologies to be introduced in the industry. One of those technologies is Android. Many of the machines in the plants have been purchased with its own control system , this system consider a remote system comparing with one in the control room which in most of the time the control system is Distributed Control System (DCS). This remote system is connected the control system through alarms and trips only. So Data communication between the remote system (Serial Device) and DCS was a must to reach any readings from the remote system. This data communication can be achievable through the Modbus. To reach more and more automated plants, the android technology has to take place in such industry which you can receive the real-time reading of any machine in the plant on your android platform (Mobile phone or Tablet). And the methodology of such technology can be achieved by many steps, starting with creating a database of readings of the DCS, this database has to be an online database to be able to retrieve data from it as long as you want, and the final part is to design an android application that responsible to retrieve the data from the online database. Such technology makes you to reach the readings of the plant from anywhere at any time. This technology is a step to create and fully automated plants, and you can supervise the plant from anywhere as long you an internet connection
