Abstract
A process plant includes a process control system having a safety system embedded therein. The integrated process control and safety system includes a host computer arranged to send and receive process level messages and safety level messages, a controller operatively connected to the host computer by a first communication network, at least one first input/output device adapted for operative communication with at least one process control field device, and at least one second input/output device adapted for operative communication with at least one safety-related field device. The first and second input/output devices are operatively connected to the controller via a second communication bus. The second input/output device includes a processor programmed to monitor both the process level messages and the safety level messages, to distinguish the process level messages from safety level messages, to select the safety level messages and to communicate with the safety-related field device based on the safety level messages.
