Method and device for remote monitoring and diagnosis of field equipment

A diagnostic unit to facilitate remote diagnosis and monitoring of field equipment, wherein the diagnostic unit is communicatively linked to a field radio device capable of communicating with a base station over an industrial wireless network, wherein the diagnostic unit comprises:

• a first input interface configured to:
• obtain a plurality of parameters of a communication channel used by the field radio device for communicating with the base station, wherein the plurality of parameters comprises packet size, data rate, Received Signal Strength Indicator (RSSI) and duty cycle, wherein at least a first parameter of the plurality of parameters is estimated with at least a second parameter of the plurality of parameters;
• a second input interface configured to:
• obtain measured data associated with the field equipment for transmitting to the field radio device, wherein the measured data comprises one or more of operation data, event data, sensor data and estimated data associated with operation of the field equipment;
• a packet generation module to:
• generate one or more packets for transmission by the field radio device based on the packet size and the data rate available for transmission, and application responsiveness required for the measured data, wherein the application responsiveness is determined based on the operation data comprising event data, wherein a generated packet size of the generated one or more packets is determined based on the application responsiveness, wherein the event data comprises a time of a generation, at the field equipment, of a packet communicating an event datum of the field equipment and a time of processing, by the base station, of the packet communicating the event datum of the field equipment, and wherein the application responsiveness is further determined based on:
• an elapsed time between the generation, at the field equipment, of the packet communicating the event datum of the field equipment and the time of processing, by the base station, of the packet communicating the event datum of the field equipment;
• and
• an output interface to:
• transmit the one or more packets to the field radio device for communication to the base station at selected time intervals, wherein the time intervals are selected based on the packet size, the data rate and the application responsiveness.
