Quick Start User Guide
1. Introduction
This manual introduces the user to the methods used to implement
the CAN-8x24 devices into their applications in a quick and easy way.
This will provide users with only basic instructions. For more detailed
information, please refer to the user manual located on the ICPDAS CD-
ROM or download it from the ICPDAS web site:
http://www.icpdas.com/download/download-list.htm
The goal for this manual is focused on helping users to quickly
familiarize themselves with the CAN-8x24 devices. Users can apply the
CAN-8x24 devices as follows.
● Complies with DeviceNet specification
Volume I, Release 2.0& Volume II,
Release 2.0

Note: If users set the illegal values of the rotary switch, the MOD led will flash when
the system is powered up. If this condition occurs, users must configure the
legal values of the switches and reset the device, and then the device should
work normally.

3. How to Start
Select the necessary ICP DAS I-8K/I-
87K IO modules of ICP DAS in your
DeviceNet application.
CAN-8124/CAN-8224 just only
supports off-line mode.
After configuring the CAN-8x24 and
creating the specific EDS files, apply
the EDS file to your DeviceNet
application.
3. Produce the corresponding EDS file.
2. Select the proper module slot No. and
name for each I-8000/I-87K module
plugged in the CAN-8x24
1. Execute CAN Slave Utility in the on-
line/off-line mode

4. Installation & Configuration
Before users first use the CAN-8x24, the CAN Gateway Utility can help to
configure and create EDS files.
Step 1: Please install the CAN Slave Utility. You can find the software from our web
site: http://www.icpdas.com/download/download-list.htm or the follow path of
“/CAN-CD/DeviceNet/Slave/CAN-8x24/Utility/ on the CD provided.
Step 2: There are 2 modes in the CAN Slave Utility. One mode is off-line and it allows
users to create EDS files off-line for the CAN-8x24. Another mode is on-line mode.
Before using the CAN Slave utility in the On-line mode with the CAN-8424, please
make sure that you have connected the COM1 port to the CAN-8424 with the available
COM port on your PC.
Note: In the on-line mode, users can define the needed assembly instance or
default assembly instance, and set the IO connection path. But in off-line mode,
we provide the default assembly instance for the CAN-8124/CAN-8224. The IO
connection path must be set via an explicit connection.

Example: In the demo, apply the I-87017 (slot 0), I-8024 (slot 1), I-8053 (slot 2) and I-
8057 (slot 3) into the CAN-8424.

6.Steps toward implementing DeviceNet applications using
the command set:
1. Request the use of the Predefined Master/Slave Connection Set.
2. Set the Master’s Explicit Request Messages to set the expected_packet _rate
attribute for the IO connection to establish an I/O Connection Object State.
3. There are two ways to access IO modules. The first method is by way of the IO
connection object. The other is by using an explicit message to set/get the IO
attribute for the application object.
4. Release the use of the Predefined Master/Slave Connection Set.
