WHEN UTILIZING MODBUS PROTOCOL ONLY
The whole part represents the address of the MODBUS register containing the value of the resource to be read or written
in the
instrument. The value after the point indicates the position of the most significant data bit in the register; if not indicated
it is taken to be zero. This information is always provided when the register contains more than one information item, and
it is necessary to distinguish which bits actually represent the data (the working size of the data indicated in the column
DATA SIZE is also taken into consideration) Given that the modbus registers have the size of one WORD (16 bit), the index
number after the point can vary from 0 (least significant bit -LSb-) to 15 (most significant bit -MSb-)
Examples (in binary form the least significant bit is the first on the right):
Important: when the register contains more than one data item, during the write operation proceed as follows:
•
•
•
read current register value
modify the bits that represent the resource concerned
write the register

Same as above. In this case, the parameter visibility value is in the MODBUS register address.
