This interface is convenient for process control applications which require not only the weight data, but also
require some uploads / downloads and / or status control. If the related parameters are adjusted for host
communication, the weight indicator will be connected to your system in Host Mode. Functions “0x03” and
“0x10” are supported.
Read Hold Registers (0x03)
This function code is being used to read the information in the register addresses which have been permitted to
be read from holding registers. The reading operation will be performed by transmitting the information about
the registry to be read as given in the “Request Table”. The indicator will evaluate the received data and will
respond the info in the format as stated in the “Reply Table” or “Error Table”.

Preset Multiple Registers (0x10)
This function code is used to edit the information in the register addresses of the holding registers which are
allowed to be overwritten. The write operation will be performed by transmitting the information about the
registry to be changed as stated in the “Request Table”. The indicator will evaluate the received data and will
respond the info in the format as stated in the “Reply Table” or “Error Table”.
