◆ Writing to Multiple Registers
Function code 10H allows the user to write multiple converter MEMOBUS/Modbus registers with one message. This
process works similar to reading registers, in that the address of the first register to be written and the data quantity are set
in the command message. The data to be written must be consecutive so that the register addresses are in order, starting
from the specified address in the command message. The data order must be high byte then lower byte.
The following table shows an example of a message where 2000H has been set with a Multi-Function Analog Output 1
and 4000H has been set with a Multi-Function Analog Output 2 for the slave 1 converter.
If parameter values are changed using the Write command, an Enter command may be necessary to activate or save the
data depending on the setting of H5-11. Refer to
H5-11: Communications Enter Function Selection on page 212 and
Refer to Enter Command on page 229 for detailed descriptions.
Note: Double the number of the data quantity for the number of bytes in the command message.
