Difference between ESD and other SIS systems

ESD systems are usually implemented to function independently and at the same time with a PCS (Process Control System). It can be integrated with any new or existing SCADA system using standard communication interfaces. While the PCS will cover its operation in normal conditions, as well as programmed operations for process power on and shutdown, the ESD systems interfere in the normal operation only when an emergency is detected that may lead to a hazardous situation.
