R80ND2 automatically determines IN/OUT area size of DeviceNet when the power is turned on according to the configuration
of the connected I/O module.
If the I/O module is an input type, input data is assigned in order from the 3rd word of IN area (R80ND2 to master device). If
the I/O module is an output type, output data is assigned in order from the beginning of OUT area (master device to R80ND2).
Assign the addresses in ascending order of the module address setting.
Status data is assigned to the first two words of IN area regardless of the congiduration of the I/O module.
Refer to the following table for the data size of each I/O module.
