2.7 General-purpose I/O signals
2.7.1 General-purpose input signals
The general-purpose inputs on the option I/O interface are all available to the user. These
are connectable to pushbutton switches or sensors and can be specified for use as needed
in the robot program or sequence program.
2.7.2 General-purpose output signals
All signals are Darlington transistor open-collector outputs. The general-purpose outputs
on the option I/O interface are all available to the user. These are connectable to pushbutton
switches or sensors and can be specified for use as needed in the robot program or sequence
program.
All inputs are initialized (cleared) when the controller power is turned on.

CAUTION
See "7. I/O connections" in Chapter
3 for a definition of NPN and PNP
specifications.

CAUTION
When the "8. DI noise filter"
parameter explained in section
12.1.3, "Other parameters", is
enabled (valid), the ON or OFF
signal width for general-purpose
input signals must be longer than 25
msec. (The "8. DI noise filter"
parameter function is enabled for the
controller software V8.23 or later
version.)
