11.1 Overview
The I/O system consists of:
- Robot computer
- System backplane
- Up to six I/O boards
The robot computer board has a processor, (I/O
computer), dedicated to handling all I/O
communications. Each I/O slot can accommodate a
variety of I/O boards.
The types of I/O boards available are:
DSQC 223 Digital I/O (24VDC),
DSQC 209 Analog I/O (0-10V),
DSQC 315 Combined I/O
DSQC 239 (RIO option available for Allen Bradley
programmable controllers.)
Along with the different types of I/O boards there are
also several different I/O board connection options.
The connection options are:
- External connections,
- Internal screw connections (24 VDC),
- Internal screw connections (120 VAC),
- Internal relay unit (220 VAC).
The type of I/O board and the use of the I/O is defined
in system parameters.
In this chapter each type of I/O board will be described
with troubleshooting diagnostics and procedures. The
different I/O connection options will also be explained
with examples of wiring different I/O devices. The
manual operation of I/O will also be discussed.
