I am making a development with a [Vaisala Humidity and Temperature Probe HMP110](https://www.vaisala.com/en/products/instruments-sensors-and-other-measurement-devices/instruments-industrial-measurements/hmp110). The read-out of the data and status works fine, however the readout of serial number, firmware version, ... does not work. This requires FC43 / 14 for reading Device Identification objects. The Modbus Flex Getter node gives the error of an unsupported / unknown function code. In this [link](https://www.vaisala.com/sites/default/files/documents/HMP60%20and%20HMP110%20Series%20User%27s%20Guide%20in%20English%20M211060EN.pdf) you find the manual of the device (p.91 for the device information object and p.86 for the function code 43 / 14).

Would it be possible in the near future to be possible to support FC 43 / 14, according to [current modbus specification](https://modbus.org/docs/Modbus_Application_Protocol_V1_1b3.pdf). The FC 43 / 14 is present as of 2006 in the secification.

Thank you for any response

You will need to raise that with the node author - likely github issues pages - you can (usually) find the like to the repository in the nodes' page on the **flows** site linked at the top of this forum.
