Quick Start User Guide
1. Introduction
This manual introduces the user to implement the i-7241D module
into their applications in a quick and easy way. This document only
provides with the basic instructions. For more detailed information, please
refer to the i-7241D user manual located on the ICPDAS CD-ROM or
download it from the ICPDAS web site:
http://www.icpdas.com/download/can/Gateway_Converter.htm
The goal of this manual is focused on helping users to quickly
familiarize themselves with the i-7241D module. Users can apply the i-
7241D module as follows.

4. How to Start
2. Configure I-7K/I-87K
IO modules by DCON
Utility
3. Configure DevicNet
gateway device and
create EDS file
4. Apply EDS file in
DeviceNet application
1. Select I-7K/I-87K IO
modules in the
DeviceNet application
5. Start to communicate
with DeviceNet master
Select the necessary ICP DAS i-7k/i-
87K IO modules in your DeviceNet
application.
Configure the baud rate, checksum,
address, data format and type code of the
IO modules by use of the DCON Utility.
Note: address must be 0x01~0x0F, and
baud rate must be the same.
3. Execute the utility in order to configure
i-7241D device and establish the EDS file.
After configuring the i-7241D and
creating the specific EDS files, apply
the EDS file to your DeviceNet
application.
1. Connect the COM 2 found on the
DeviceNet gateway device & these IO
modules.
2. Connect the COM1 of the i-7241D with
the PC’s COM port via the download cable,
CA0910.

5. Hardware Installation
Before using the i-7241D, users must configure the DCON modules by using
DCON Utility tool. Then configuring the i-7241D by using the CAN Gateway Utility, as
shown in the following steps.
Step 1: Please install the CAN Gateway Utility. You can find the software from our
web site: http://www.icpdas.com/download/can/Gateway_Converter.htm or the CD
path of field_bus CD://DeviceNet/Gateway/i-7241d/utility/.
Step 2: Before using the utility tool, connecting the i-7000 modules and the i-7241D
correctly. Then turn off the i-7241D and connect the INIT* pin with the GND pin.
Step 3: Turn on the i-7241D. Execute the CAN_GW.exe file. The startup figure would
be displayed.

Step 4: Press the “Connect” button to connect the i-7241D. Then the “Com Port Scan
Parameter Setting” dialog will be pop-up as follows. Please set the correct Com port
communication parameters to scan the i-7000 modules. Then press the “OK” button to
scan the modules.
Step 5: After scanning the i-7000 modules, the result will be compared with the
parameters stored in the EEPROM of the i-7241D. If any difference has been detected,
the warning message will be popped up.
Step 6: Otherwise, a related information dialog box will be displayed as following
figure. The users can set the ID and baud rate of the CAN Channel.

Step 7: Press “Build EDS file” to start to build the specific EDS file for the i-7241D. If
the I/O connection path stored in EEPROM of i-7241D is not matched with before
setting, the warning dialog box would pop-up.
Step 8: Start to build the specific EDS file for your DeviceNet gateway. The DeviceNet
EDS file information is according to the following dialog box. Users can configure the
relative information for their EDS file by using following dialog box.
Step 9: Setting the EDS file information and give it a description in the description box
and the poll, strobe-bit and COS/Cyclic connection path.

Step 10: When setting these connection paths, users can refer to the DCON modules,
application and assembly objects by these icons.
Step 11: The last step is to press the “Finish” button to create the EDS file and store
these information into the i-7241D’s EEPROM. You can find the EDS file
“DNS_DCONx.eds” in the path of CAN_GW.exe.
6.The relation of application and assembly objects
The components of Assembly Objects
Example: In the demo, apply i-7066 (address 0x01), i-7033 (address 0x04), i-87024
(address 0x05) and i-87053 (address 0x06) in the system.

7.Steps to implement the DeviceNet applications by
using the command set
1. Requests the use of the Predefined Master/Slave Connection Set.
2. Send the Master’s Explicit Request Messages to set expected_packet_rate
attribute of IO connection and make I/O Connection Object State established.
3. There are two ways to access IO modules. The first method is by the way of
the IO connection object. The other is by using an explicit message to
set/get the IO attribute of application object.
4. Release the use of the Predefined Master/Slave Connection Set.
