Claim Text:
1. A system, comprising: a sensor that is configured to output a first time-series signal that is indicative of a parameter of an operating condition of a process in an industrial environment; a sensor sentinel computing device that is in wired communication with the sensor and receives the first time-series signal, the sensor sentinel computing device performing a computing operation on the first time-series signal to generate a first validation signal that is a function of the first time-series signal; and a programmable logic controller that is in wired communication with the sensor sentinel computing device, the programmable logic controller comprising: the system further comprising: a database system that receives the first time-series signal and the first validation signal from the programmable logic controller and causes the first time-series signal and the first validation signal to be retained in relation to one another in a non-transitory computer-readable data storage in a database; wherein validation indicates if the first time-series signal stored in the database has been be altered; and wherein the comparison signal causes a message to be delivered to an operator if the comparison indicates that the second validation signal fails to match the first validation signal.
