[Rules for setting RIO assignment parameters]
 For arbitrary device assignment, assign PLC devices to all stations which are connected to the remote units with DI/DO
function. Devices can be assigned in random order for arbitrary device assignment. It is unnecessary to assign in order of
the target channels, target station numbers, PLC devices, etc.
 Set the PLC device numbers after setting the PLC device names.
A setting error occurs if PLC number is input when the PLC device name is in the unset (blank) state. When a PLC device
name is changed, PLC device number of the same parameter set number is cleared to zero.
 When setting the bit devices, set the DI and DO device numbers in increments of 32 points. A setting error occurs if device
number is not a multiple of 32 (20 for hexadecimal).
 When setting the word devices, set the DI and DO device numbers in increments of two words (32 bits).
A setting error occurs if the device number is odd.
 Set the target channels to "0" for the parameter sets which are not set for device assignment. The setting state of the
parameter sets to which "0" has been set for the target channel will not be checked.
 The RIO assignment parameter setting values are retained even when the fixed device assignment and arbitrary device
assignment are switched.
[RIO assignment parameter setting state check ("Device Setting Check")]
 The RIO assignment parameter setting state can be checked without rebooting the power by setting the RIO assignment
parameter "Device Setting Check" to "1" when performing the arbitrary device assignment.
The RIO assignment parameter setting state will not be checked at the fixed device assignment.
 The RIO assignment parameter settings cannot be valid only by inputting "1" to "Device Setting Check". To enable the arbi-
trary device assignment, turn the power OFF and ON after the RIO assignment parameter settings.
 The value of "Device Setting Check" goes back to "0" after the check for the RIO parameter setting state is completed.
 The RIO assignment parameter setting state of each remote I/O unit station with the analog input/output and safety DI/DO
functions will not be checked.
 The setting state of the parameter set which has been set as the station unconnected to the NC control unit will not be
checked.
 The setting state of the parameter sets of which the target channel number has been set to "0" will not be checked.
