W** register is designed for writing, but direct write is not available, for details see

x
at transmit are register addresses indexed from zero - „zero based addressing“.
For example „measured temperature“ with Modbus address 0x31 is physically sent
along data bus as value 0x30. You make sure of correct addressing with the aid of
Master device documentation or experimentally (e.g. for „measured temperature“ try
to use address 0x31 or 0x30).

Note:
In case there is a need for reading of measured values from the device with higher resolution
than one decimal, measured values in device are stored also in „Float“ format, which is not directly
compatible with IEEE754.
6.1.4. Far controlling of output relays status
2
There is possible to control output relay status (open/close) with using of Modbus communication
protocol. To this function enable, there is necessary to assign one of following options to relay:
FAR0 – „Far condition 0“, it means, after power up output relay will be open, or
FAR1 – „Far condition 1“, it means, after power up output relay will be close.
2
This function is available from firmware version 04.06. If older firmware used, update your firmware or contact device’s
distributor.
