The input/output signals (analog signal, DI/DO, etc.) are assigned to the PLC devices, and the digital signals (DI/DO) can be
assigned to the arbitrary PLC devices by the parameters.
Either "Fixed device assignment" which automatically assigns the signals to fixed PLC devices defined by the system or
"Arbitrary device assignment" which user can assign the signals the arbitrary PLC devices by the parameters can be selected
by setting the RIO assignment parameter "#53001 RIO dev assign (selection of RIO device assignment method)".
[Fixed Device assignment]: Parameter "#53001 RIO dev assign" = 0
Settings are not required because the assignment to the fixed PLC devices are automatically performed.
Refer to "17.6.4.1 Fixed Device Assignment" for more details.
[Arbitrary Device assignment]: Parameter "#53001 RIO dev assign" = 1
Set the PLC devices which are assigned to the DI/DO of each remote I/O unit station by the parameters.
