2.5 Using the Modbus Slave Function
The DX is used as a Modbus slave.
For the Modbus specifications, see section 6.3.
Setting the Serial Communication
Select Modbus as a protocol on the Basic settings. For detail, see section 2.4, “Setting
the Serial Communication.”
Reading/Writing the DX Data on Another Device
Another device (master device) sends commands to the DX to read the DX data or write
data to the DX. You can perform some operations, such as memory start, by writing in
the registers.
For the function codes that the DX supports and the DX registers that the master device
can access, see “Modbus Server Function” in section 6.3.
