6.2.1 Measuring values (Input Register)
All measuring values of the weather station WSC11 consume 32Bit, i.e. 2 MODBUS register
addresses. The following table shows the allocation of measuring value to register address, while the
measuring values are sorted as follows:
-
By measuring value type (30001 to 34999).
-
In unbroken sequence (35001 to 39999).
