Introduction - ABB Scalable I/O Applications Manual

1 Introduction

General
ABB Scalable I/O is a modular, compact, and scalable I/O system that consists of
a digital base device, or a safety digital base device, which is the minimum
configuration, and add-on devices.
Up to four add-on devices can be controlled by each base device with maintained
performance, and any combination of add-on devices is supported.
Communication
The digital base device communicates over the EtherNet/IP communication protocol
to the robot controller or to other EtherNet/IP scanners. Up to 20 devices in total
can be connected to the robot controller over EtherNet/IP. This includes digital
base devices and other third-party I/O devices.
Node commissioning for other EtherNet/IP scanners
For other EtherNet/IP scanners, node commissioning needs to be done either using
a dhcp server on the scanner network or setting a static IP address in the device
with the help of third-party software. An initial volatile address can be obtained
using the reset button. The TCP/IP Object can then be accessed for the purpose
of this.
Options
When using the standard Plug & Produce interface, no additional RobotWare
options or hardware options are required to connect to the robot controller.
When using the RobotWare options 3024-1 EtherNet/IP Scanner and/or 3024-2
EtherNet/IP Adapter, more configuration possibilities are available.
Device interfaces
The add-on devices have an optical interface and must be attached to a digital
base device. The additional Ethernet port on the base device can be used to daisy
chain any Ethernet based equipment on the same network, for example additional
digital base devices.
Safety
The safety digital base device can be used to control and monitor machine safety
equipment in a system. It uses dual channels, meaning that no undetected single
fault can lead to loss of safety functions.
Mounting
The I/O devices are designed to be mounted vertically on a mounting rail in an
IP20 protected environment with normal air convention. Forced air is needed if the
devices are mounted horizontally.
