Classification: CPC G  H | IPC H

Claim 7:
8. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:
determining, by a first Safety Instrumented Function (SIF) by analyzing readings and associated trends on one or more pieces of equipment, that a process equipment event affecting process safety of the one or more pieces of equipment is predicted to occur in a first system as detected by the first SIF, including identifying, based on the process equipment event occurring, a first action to be performed by the first SIF;
performing, by the first SIF, the first action in the first SIF to prevent an occurrence of a first hazardous event in the first system;
determining, by a highly-reliable, self-healing communication transmission network using the first action and connecting the first SIF and a second SIF in a second system, a second action to be performed in the second SIF to prevent the occurrence of a second hazardous event affecting process safety in the second system;
providing, by the highly-reliable, self-healing communication transmission network to the second SIF, a notification that the second action is to be performed to prevent the occurrence of the second hazardous event in the second system;
performing the second action to prevent an occurrence of the second hazardous event affecting process safety in the second system; and
determining, by the highly-reliable, self-healing communication transmission network, that performing the second action leads to achieving a safe state of the highly-reliable, self-healing communication transmission network.
