Abstract

Provided in some embodiments are systems and methods for emergency shutdown (ESD) systems. Embodiments provide for receiving, from a central logic solver (CLS) of an emergency shutdown (ESD) system for a plant via a first communication channel, a command indicative of a first state for an ESD valve, in response to receiving the command, controlling the ESD valve to operate in the first state, obtaining, from a central status monitor (CSM) of the ESD system via a second communication channel, current status information for the plant, determining a second state for the ESD valve based at least in part on the current status information obtained from the CSM, and controlling the ESD valve to operate in the second state.
