Abstract: PLC and SCADA-based automation systems are the most widely used industrial automation systems today, owing to their numerous advantages. The specialized requirements and customization in various aspects of radiological once through ventilation system necessitate the requirement of efficient control and modernization in existing hardwired interlocked system. With the existing hardwired interlocking between the sub systems, there were certain operational challenges and unsafe operating conditions. The existing system lacked certain key features such as Working/Standby changeover and Mains/Standby selection for any sub system. Also, the manual regulation of control equipments in event of system changeover and during the normal operation manual throttling of damper actuators to achieve desired optimum performance, lead to inefficient control. This arose the requirement of sophisticated advanced automation system for simple and safe operation. The automation system with utilization of PLC and SCADA systems including the networking components represents the most efficient way to improve the radiological once through ventilation system. This paper elucidates the various design criteria & features, as well as the sizing and selection of various automation components, and the development activities performed for implementation of hot standby PLC and redundant SCADA based monitoring and control system for radiological once through ventilation systems catering to an important facility at BARC South Site Trombay.
