Chapter 1 Introduction
1.1 Overview
The CAN-8x24 series are the DeviceNet remote I/O units produced by ICP
DAS for data acquisition and the control system that provides a wide range of
capabilities, most specifically for real-time applications. A DeviceNet master
operating via a DeviceNet protocol remotely controls the CAN-8124/
CAN-8224/CAN-8424 series products. In others words, the CAN-8124/
CAN-8224/CAN-8424 series can be a DeviceNet slave devices in the CAN on
the DeviceNet network. Furthermore, the CAN-8124/ CAN-8224/CAN-8424’s
main unit are small and middle size compact devices, but it offers many good
features to the users.
The CAN-8124/ CAN-8224/CAN-8424’s main control units are based on
the modular design which offers many good features to users and provides
more flexibility in data acquisition and a control system for the DeviceNet
network. In order to expand the I/O channel to make it more flexible,
CAN-8124/ CAN-8224/CAN-8424 supports 1,2 and 4 expansion slots
respectively for user to expand their I/O channel numbers in various DeviceNet
applications. Users can configure the I-87K or I-8000 IO series modules to fit
their customized applications. The symbol ‘x’ in the I-8x24 represents that how
many expansion slots there are in these main control units. Each expansion
slot can have one I-87K or I-8000 series I/O module plugged into it. For
example, an CAN-8124 has one expansion slot, and an CAN-8424 has 4
expansion slots. All of these main control units follow the DeviceNet
specification Volume I, Release 2.0& Volume II, Release 2.0. In addition, ICP
DAS also provides the CAN Slave Utility to create the EDS file dynamically and
to configure DeviceNet slave devices. Therefore, users can easily apply the
CAN-8124/CAN-8224/CAN-8424 embedded controller into the DeviceNet
network. The general application architecture is demonstrated in figure 1-1:
