(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) 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 are not connected to the station which has been 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 PLC device are set redundantly to the
RIO assignment parameter #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 NC control unit.)
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.
(10) PLC fixed signals (stroke end +/- and reference position return near-point detection) acquire the input signals from
the RIO units assigned to the fixed devices when the arbitrary RIO assignment has been performed.
