20.6.4.2 Arbitrary Device Assignment
Parameter setting for device arbitrary assignment
(1) By setting the parameter "#53001 RIO dev assign" to "1", the assignment method for PLC devices to be used for
input/output of each remote I/O unit station becomes arbitrary device assignment.
(2) For arbitrary device assignment, set the PLC devices for input and output to DI/DO (32 points) of each remote I/O
unit station by the parameters. Also, set the assignment of the operation panel I/O unit.
(3) Turn the power OFF and ON to enable arbitrary device assignment after the parameter settings.
(4) Set the input/output device assignment and high-speed input/output specification by the parameters for each
station of all remote units which have DI/DO function (except safety DI/DO). If all stations have not been set, the
alarm "Y05 Initial parameter error" will be issued when the power turns ON.

(Note 1) A set of RIO assignment parameters consists of eight parameters (from target channel number to
high-speed output specification) for one station.
(Note 2) Arbitrary device assignment cannot be performed for the system-occupied stations of RIO3 and
operation panel I/O unit-connected channels.
(5) The PLC devices that are valid for arbitrary device assignment are as follows:
PLC device
X
Y
ZR
(Note 1) Duplication check is not performed between the PLC devices which are set with machine input/
output signal other than the remote I/O such as CC-Link or PROFIBUS and PLC devices which are
set with arbitrary device assignment. If the PLC devices have duplicated, NC or PLC ladder can not
be carried out correctly. When using machine input/output signal other than the remote I/O, make
sure to confirm that the PLC devices do not duplicate the PLC devices set with arbitrary device
assignment.
(Note 2) Assignment cannot be performed for the devices corresponding to the system-occupied stations of
RIO3. If you connect the operation panel to any channel other than RIO3, assignment is also
disabled for the devices corresponding to the system-occupied stations of the said channel.
(6) Even when the RIO assignment parameters are set in the remote I/O unit stations which have the analog input/
output and safety DI/DO functions, the input/output is not carried out to the set PLC devices.
