ABSTRACT:
A diagnostic concentrator includes a first interface that is capable of receiving a signal sent from a field device to a process controller. The signal includes a primary process variable and additional information. The diagnostic concentrator also includes a controller that is capable of generating a message corresponding to the received additional information and a second interface that is capable of transmitting the generated message. The first interface may be a HART interface. The second interface may be a wireless interface or a network interface. The message may be transmitted to a diagnostic monitor or a process controller. The first interface may receive a plurality of signals sent from a plurality of field devices to the process controller. The controller may generate a plurality of messages corresponding to the plurality of additional information in the signals and transmit the messages via the second interface.
