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.
c
CAUTION
If the "DI noise filter" parameter is
set to "VALID" (refer to "12.1.3
Other parameters" in Chapter 4), the
on and off periods of input signals
must be longer than 25msec.
