Abstract: A field device includes process communication circuitry configured to communicate in accordance with a process communication protocol. A controller is coupled to the process communication circuitry. The controller includes timing circuitry and is configured to generate periodic time signals during an operational period of the field device and store an indication of operational time based on the periodic time signals in non-volatile memory. The controller is configured to employ the process communication circuitry to provide an indication of operational time to a remote device.
