Abstract: A system includes, but not limited to, at least one processor, a retriever configured to retrieve a first field device parameter belonging to burst mode settings from at least one field device connected to a field network, and a transmitter. The transmitter is configured to transmit a second field device parameter belonging to burst mode settings to the at least one field device, based on at least a configuration file. The second field device parameter being associated with the first field device parameter. The first field device parameter includes, not limited to, a first determiner that determines whether to enable or disable a first automated transmission of a first process related variable of the field device, the first process related variable is one of a process variable and a diagnostic result in a burst mode. The retriever, the comparator and the transmitter are implemented by the at least one processor.

Abstract: An engineering tool is provided with a first connector that connects to a first field device, a second connector that connects to a second field device, a controller, and, switch that switches the connection to the controller between the first connector and the second connector. Upon receiving instructions for transferring engineering information, the controller switches the switch to the first connector, acquires predetermined engineering information from the first field device, subsequently switches the switch to the second connector, and configures the second field device with the predetermined engineering information thus acquired.
