3.6.2 Scalable I/O, internal and external
General
The controller can be fitted with an internal I/O unit, DSQC1030, with 16 digital
inputs and 16 digital outputs. The controller can also use external I/O units, with
DSQC1030 as base unit and add-on units as extension.
Scalable I/O units
The I/O unit DSQC1030 Digital Base belongs to the ABB Scalable I/O system, which
is a modular, compact, and scalable I/O system that consists of a base device
(minimum configuration), and add-on devices.
The base device has a Plug & Produce interface and communicates over the default
EtherNet/IP communication protocol to the robot controller. When using the standard
interface, no additional RobotWare options or hardware options are required to
communicate with the robot controller. When using the RobotWare option
EtherNet/IP Scanner/Adapter , more configuration possibilities are available.
For more information about installing, configuring, and using the scalable I/O units,
see
Application manual - Scalable I/O .
Safety digital base device
The safety I/O unit DSQC1042 Safety Digital Base is a device that can be used to
control and monitor machine safety equipment in a system. The device can be
used together with the add-on devices. It uses dual channels, meaning that no
undetected single fault can lead to loss of safety functions.
