5.9.4. Register map
In the PCE-P30U transducer the data is stored in 16- and 32-bit
registers. The process variables and parameters of the device are
stored in the different address space depending on the variable type.
The bits in the 16-bit registers are numbered from the least significant
to the most significant (b0 … b15). The 32-bit registers (4 Bytes) contain
floating-point values in IEEE-754 standard. Bytes sequence: B3 B2 B1
B0 – the most significant byte is sent as the first one. 16-bit registers
which represents 32-bit values on a two following registers are multiplied
at different address field with different bytes (word) order: B1 B0 B3 B2
(table. 36).
Register map of the PCE-P30U transducer is shown in table 36.
Note:
All the given addresses are physical addresses. In some
computer programs logical addressing is applied, then the addresses
should be increased by 1.
