Abstract

An industrial control system includes a first and a second safety program executing in tandem on a first and a second safety controller, respectively. A first and a second fault condition is detected with the first or the second safety program, respectively. A third fault condition is detected by either the first or second safety programs. Monitoring for the third fault condition by the first or second safety programs is disabled upon detecting the first or second fault condition, respectively. A safe operating state is entered when either the first or second safety program detects the third fault condition. The industrial control system operates at a first safety level while both the first and second safety programs monitor the industrial control system for the third fault condition and at a second safety level, lower than first safety level, when either the first or second fault condition is detected.
