Having a system in good condition is not enough to be totally efficient. Many systems can improve their efficiency considerably if an operative logic is generated where, through programmed steps, the system can be autonomous.

Also, having a remote monitoring and control can help you to know if the system operates correctly, if it suffered any damage and even make emergency stoppages or generate actions remotely.

Para generar un monitoreo remoto (telemetrĂ­a) o un control remoto (telecontrol), generalmente se utilizan los siguientes elementos:Para generar un monitoreo remoto (telemetrĂ­a) o un control remoto (telecontrol), generalmente se utilizan los siguientes elementos:

  • Instrumentation:It is the set of sensors that help us measure the required parameters. The correct selection of these equipment is extremely important since for the same application there are different types of meters, for example, for measurement of flow a variety of measurement techniques exerts such as reel meters electromagnetic, ultrasonic reel, ultrasonic clamp-on , electromagnetic insertion, coriolis, etc. These same devices have different communication protocols, such as Modbus RS-232, Modbus RS-485, Modbus TCP / IP, Devicenet, Profinet, 4-20mA, Hart, etc. These communication protocols have certain advantages and characteristics that differentiate them from others, among the characteristics we can mention the maximum transmission distance, accuracy, ability to connect in series with other equipment, the number of data sent by each sensor, etc

  • Control:This element is generally known as Programmable Logic Controller (PLC) for its acronym in English, likewise, when this PLC is combined with a series of additional attachments such as power supply, communication modules, power backup modules, it is called Remote Terminal Unit (UTR). This equipment is in charge of receiving the information provided by the sensors (instrumentation) and processes the information internally to generate actions according to the operating logic that has been established, such as stopping pumping when the tank is emptying; likewise, it sends the signals already processed to the SCADA system through a communication system. It is important to properly select the controller since it should not be limited in the processing capacity or in the number of inputs and outputs, communication protocols, redundancy, etc.

  • Communication: Many times, the area where the monitoring is located is far from the offices of the managers, either by a couple of meters or even hundreds of kilometers. Depending on the conditions of the site, the size of the data packet to be transmitted, the required reliability, the appropriate communication method is selected, whether by optical fiber, radiofrequency, satellite, GPRS, etc. The importance of correct selection will determine the transmission capacity and reliability in communication

  • SCADA/HMI:This system of Supervision of Control and Acquisition of Data (SCADA) by its abbreviations in English allows the management and control of any local and remote system through a graphic interface which communicates the user with the system, this, it is a software that is mounted on an industrial computer and it is programmed graphically the elements that the system contains, later it is assigned actions depending on the information that is being received in the field through the instrumentation. The SCADA system allows to see in real time the parameters in the field, to manage actions such as turning on, turning off or restarting a computer, generating alarms by established thresholds, storing the information in a database, displaying historical graphs, among many other things. This software will help us to understand and visualize everything that happens hundreds of kilometers, directly from our screen.

COET performs the selection, supply and installation of the instrumentation, control equipment and type of communication required, integrating all the data in a SCADA platform where the graphic interface is programmed in the closest way to reality, we have SCADA 3D systems where the structures, equipment and instrumentation are scaled.
