Abstract
A diagnostic system and method for a field device implemented in a safety instrumented system includes detecting an occurrence of a safety event associated with the field device, overriding normal control of the field device to cause the field device to enter a safe state in response to the detected occurrence of the safety event, verifying the override of normal control of the field device, and transmitting a control signal to cause the field device to enter the safe state.
