This indicates detection of the HART over IP Pass Through Request Read PV Sensor Information command.
This command reads the PV sensor limit and span. The command is implemented for the HART protocol conformance but the data are not used for the flow meter application.
Highway Addressable Remote Transducer (HART) is a standard for sending and receiving digital information across analog wires between smart devices and control or monitoring systems. The protocol has added the implementation of HART over IP.
