Patent ID: 8649888

Claim:
A system for monitoring and control of a plurality of field devices separately provided in a safety subsystem and a process control subsystem, the field devices including safety subsystem field devices associated with one or more processes or subprocesses and process control subsystem field devices associated with one or more of the processes or subprocesses, the monitoring and control system comprising: a memory that stores complementary field device data including mappings of safety subsystem field devices and process control subsystem field devices corresponding to the same process or subprocess, such that a safety subsystem field device that becomes compromised is mapped to a healthy complementary process control subsystem field device corresponding to the same process or subprocess, and such that a process control subsystem field device that becomes compromised is mapped to a healthy complementary safety subsystem field device corresponding to the same process or subprocess; a processor coupled to the memory; and a coordination module executable by the processor, wherein the coordination module monitors the health of the process control subsystem and safety subsystem field devices, and upon determining that a particular field device is in a compromised state, delegates a function or functions of that compromised field device to its complementary field device as indicated by the complementary field device data.
