17 Setting the Hardware
(7) Up to 24 stations can be specified for high-speed input/output specification each for input and output. If 25 or more
stations are specified, the alarm "Y05 Initial parameter error" will be issued.
(8) High-speed input/output specification can be set by R registers below as well as the RIO assignment parameters.

(Note 1) Turn the power OFF and ON after the R register settings to enable the settings.
(Note 2) One bit of each R register is equivalent to one station. The high-speed input/output specification can
be performed by turning ON the R register bits of the stations to be input or output with PC high
speed. To output the 10th station of RIO1 at high speed, for instance, turn BIT9 of R30544 ON.
(Note 3) High-speed input/output designation is disabled for the system-occupied stations of RIO3 and
operation panel I/O unit-connected channels. Even when the BIT6 to BITD of R30552 and R30568
are turned ON, they will be invalid.
(Note 4) The above settings are invalid with fixed device assignment.
(9) 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 parameter #1 to #5 as shown in the table below. (Both the 1st and 2nd stations are
connected to NC control unit.)
Parameter set No.#n
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.
