Measurement data registers - HMD110 - HMD112 - HMS110 - HMS112 - HMW110 - HMW112 - TMD110

Table 1. HMD110/112, HMW110/112, and HMS110/112 Modbus measurement data registers (read-only)
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.
