Dedicated input/output
The functions shown in
are available for the dedicated input/output signals. These are used by the
parallel input/output unit by assigning the signal No. in the parameter.
The signal No. is assigned by the signal No. used in the order of "input signal" and "output signal" in each
parameter. Refer to
Page 83, "3.15 Operation of parameter screen"
for details on setting the parameters. If
a "-1" is designated for the assigned signal No., that signal will be invalidated.
The I/O parameters can be set on the T/B parameter screen or by using the maintenance tool of the PC sup-
port software (optional). And refer to
Page 580, "6.5.2 Timing chart example"
for time chart.
To use the dedicated I/O signals, set the controller mode to AUTOMATIC, and turn on the operation rights
input signal (IOENA) beforehand.

Output Remote mode output
This output indicates that the controller mode
is set to AUTOMATIC and remote operation
mode.
This signal must be turned ON before any con-
trol tasks using I/O signals can be performed.

Output Operation rights output
signal
Outputs the operation rights valid state for the
external signal control.
The operation right is given when the opera-
tion right input signal is ON, the controller
mode is set to AUTOMATIC, and there is no
other device that currently has the operation
right.

Input
Start input
This input starts a program. To start a specific
program, select the program using the pro-
gram selection signal "PRGSEL" and numeri-
cal input "IODATA," and then input the start
signal. Note that when the parameter "PST" is
enabled, the system reads the program num-
ber from the numerical input (IODATA) and
starts the corresponding program (i.e., pro-
gram selection becomes no longer neces-
sary).
All task slots are executed during multitask
operation.
However, slots whose starting condition is set
to ALWAYS or ERROR via a parameter "SLT*"
will not be executed.

Output Operating output
This output indicates that a program is being
executed. During multitask operation, this sig-
nal turns ON when at least one task slot is
operating.
However, slots whose starting condition is set
to ALWAYS or ERROR via a parameter "SLT*"
will not be executed.
