Dedicated input/output
The functions shown in
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
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).
To use the dedicated I/O signals, set the key switch on the operation panel to AUTO (Ext.) beforehand.

Outputs that the power has been turned ON
and that the external input signal can be
received.
-
This output indicates that the key switch on the
operation panel is set to AUTO (Ext.), which is
a remote operation mode.
This signal must be turned ON before any con-
trol tasks using I/O signals can be performed.
-
operation panel is set to Teaching mode.
-
operation panel is set to AUTO (OP),
Sets the validity of the operation rights for the
external signal control.
Outputs the operation rights valid state for the
external signal control.
The operation right is given when the operation
right input signal is ON, the mode switch is set
to AUTO (Ext.), and there is no other device
that currently has the operation right.
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 necessary).
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.
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.
