Measurement Data Registers
Accessing unavailable (temporarily missing) measurement data does not generate an exception.
“Unavailable” value (a quiet NaN) is returned instead.
Measurement output is shown in metric units. If non-metric values are needed in Modbus use, the
units shall be converted in the Modbus master (PLC) using the scaling functions typically available.
