Thank you very much for your package. Is it possible to read the Device Identification information? E.g. serial number of TH probes etc.

Thank you,

I tried copy/adapting read_holding_registers in client.py but it's obviously a bit more complicated than that ...

This is now available in pyModbusTCP version 0.2.1.

from pyModbusTCP.client import ModbusClient

mc = ModbusClient(host='myserver.example.com')
dev_id_resp = mc.read_device_identification()
print(f'vendor={dev_id_resp.vendor_name}')
