2.2 Relation of RIO Unit and Devices
 In the following cases, the alarm "Y05 Initial parameter error" will be issued when the power is turned ON. The number of
the RIO assignment parameter with illegal setting state will be displayed.
(a) The value outside the range of setting has been set to the RIO assignment parameter (except "#53001 RIO dev
assign").
(b) Two or more stations of the target channel No. and the target station No. are set redundantly to the RIO assignment
parameters.
(Example) The power is turned ON in a state where the 1st and 2nd station of RIO1 are set redundantly to the RIO
assignment parameters #1 to #5 as shown in the table below.
(Both the 1st and 2nd stations are connected to the NC control unit.)
Target channel No.

#N (Parameter No.)
1 1 (#53011)
2 1 (#53021)
3 1 (#53031)
4 1 (#53041)
5 1 (#53051)
<Result>
The parameter number (53031) of "Target channel #3" will be displayed on the alarm "Y05 Initial parameter error".
Duplication error of RIO1 second station will be detected first because the RIO assignment parameter is checked from the
top. Between the parameter set #2 and #3 to which second station of RIO1 are set, parameter set #3 which is the latter will
be displayed as the alarm.
(c) A PLC device outside the assignable range has been set to the RIO assignment parameter.
(d) 25 or more stations have been specified with the high-speed input or output with the RIO assignment parameters.
(e) The RIO assignment parameters have not been specified to the remote I/O unit stations with DI/DO functions (except
safety DI/DO) that are connected to NC.
(f) Two or more stations of the PLC devices are set redundantly to the RIO assignment parameters.
Note
(1) However, these (a) to (f) will not be issued with the alarm "Y05 Initial parameter error" in the following cases:
- "0" has been set to the target channel.
- Remote I/O unit with DI/DO function is not connected to the station specified with the target channel and station
number.
- The parameter "#1238 set10/bit3" is ON (the input from RIO is ignored).
(Example) The power is turned ON in a state where the X100 and X200 of the PLC device are set redundantly to the RIO
assignment parameters #1 to #5 as shown in the table below.
(All stations which has been set to the RIO assignment parameters #1 to #5 are connected to the NC control unit.)
Parameter set No.#n
#N (Parameter No.)
1 X (#53013)
2 X (#53023)
3 X (#53033)
4 X (#53043)
5 X (#53053)
<Result>
The parameter number (53034) of "DI device No. #3" will be displayed on the alarm "Y05 Initial parameter error".
Duplication error of X200 will be detected first because the RIO assignment parameter is checked from the top. Between
the parameter set #2 and #3 to which the X200 are set, parameter set #3 which is the latter will be displayed as the alarm.
