A control system generally consists of equipments, a software package and an electronic control layer which handles human-machine interaction, usually referred to as a Human Machine Interface (HMI). It generally has numerical set points, buttons, and displays which allow the operator to interact with equipment and control it. The visual aid also allows the individuals to troubleshoot faults and get general information, including status, flows, levels, pressure, etc. about the entire system at one place in real time.
To develop the preliminary documentation which is necessary to implement a successful process control system. This documentation includes a process control network (PCN) architecture diagram, required specifications of control system, a control narrative, a complete instrument index, interlock notes as well as other standard documentation.
Control Systems Design is a strenuous venture. It involves varying factors like panel production, testing and then staging of the entire system. Next, one more testing is conducted which is addressed as integration testing, following to its customer examination is done and lastly FAT Factory Acceptance Testing is conducted.
No doubt, panels play a crucial part in linking the operator interface and the relevant field instrumentation thereby fabricate a fundamental constituent of overall control approach. When the design is adequate and flawless it will be of paramount value. Today when the processing plants are emerging multifaceted and compact, suitable panel outline and well-organized utilization of accessible space appears a lot more crucial to deem about. While designing the control panel, it must be remembered that it is not meant for today, but it should continue for future days as well. While venturing out for quality professionals you will find more than hundreds but you must make sure that he is efficient out and out to understand your requirement and render service in that accordance. The control system ranging from layout, pattern to construction and testing should be of international standard.
Being a Control Systems Design engineer is a challenging career option, therefore there is a lack of skilled individuals who can work in this domain. Due to this reason, companies find it quite difficult and time consuming to find individuals with hands-on expertise in control system engineering. Hence, for them, it’s more convenient to find third party firms that could help them design and develop their custom control systems. These firms provide assistance from designing to development and validation of these systems, thereby cutting off the majority of worries of the company. They are highly-experienced professionals who have gone through simple to complex projects of the clients.
A control engineer is responsible for designing the entire system based on these parameters and documentations. He uses various equipments and sensors to measure the output performance of the device being controlled. The gathered measurement data is then used to give feedback to the input actuators that can make rectifications toward desired performance. The devices that don’t require human intervention at all for their operation are called automated devices. Automated test equipment (ATE) is one such example of such a device.
