Quick Start User Guide
1. Introduction
This user guide introduces the user how to implement the I-7242D
module into their applications in a quick and easy way. Therefore, it only
provides the basic instructions. For more detailed information, please refer
to the I-7242D user manual located on the ICPDAS CD-ROM or download
it from the ICPDAS web site:
ftp://ftp.icpdas.com.tw/pub/cd/can_cd/devicenet/gateway/i-7242d/manual/
The sake of this manual is focused on helping users to quickly
familiarize themselves with the I-7242D module. Users can apply the
I-7242D module as follows.

Step2. It means that the I-7242D is in the
normal operation mode. Its MAC ID is 0x03.
CAN baud rate is 125 Kbps and RS-485 baud
rate is 115.2 Kbps.
Step3. It means that there is one message lost
from I-7242D to Modbus device which device
address is 0x01. The number format is hex.

4.Configuration Flowchart
Select the necessary Modbus RTU devices
in the DeviceNet networ
k
.
1. Connect the COM2 port from the I-
7242D to these Modbus RTU devices.
2. Connect the COM1 port from the I-
7242D to the PC’s COM port with the
download cable, CA0910F.
2. Power on the I-7242D and execute the
DNS_MRU Utility in order to
configure the I-7242D. Then it will
establish the EDS file automatically.
After configuring the I-7242D and creating
the specific EDS files, apply the EDS file
in your DeviceNet application.
1. Initial the I-7242D by connecting the
Init * pin with the GND pin.

5.Software Installation
Before users use the I-7242D, they must configure the I-7242D by the DNS_MRU
Utility. Please do following steps to configure the I-7242D.
Step 1: Please install the DNS_MRU Utility. You can find this configuration tool from
our web site: ftp://ftp.icpdas.com.tw/pub/cd/can_cd/devicenet/gateway/i-7242d/utility/
or the CD-ROM disk following the path of /CAN-CD/ DeviceNet/ Gateway/ I-7242D/
Utility/.
Step 2: Before you use the software, connect the I-7242D with your computer
correctly. Then turn off the I-7242D and connect the INIT* pin with the GND pin of the
I-7242D.
Step 3: Turn on the I-7242D. And execute the DNS_MRU Utlility.exe file. Thus the
startup figure would be displayed.

Step 4: Select PC’s COM port correctly. Then press the “Connect” button to connect
with the I-7242D. Then it would take few seconds to read the communication
parameters stored in the I-7242D’s EEPROM.
Step 5: After reading parameters from EEPROM, a related information dialog box will
be displayed. Then you can set the CAN and COM port parameters to what you need.

Step 6: After setting the CAN and COM port parameter, press the “Next” button to
start to set their Modbus devices parameters. Users can use the add button, erase
button, update button or delete button to modify their Modbus devices parameters.
And users can view the information of devices, application object and assembly object
by clicking these “View” buttons.
Step 7: After the configuration of Modbus devices parameters, press the “Next” button
and start to build the specific EDS file for the I-7242D. Set the EDS file information and
give it a description in the description box. Then set the poll, strobe-bit and COS/Cyclic
I/O connection path for the I-7242D.
I-724D DNS/Modbus RTU Quick Start User Guide, July 2006, Version 1.1 ------ 7
Step 8: The last step is to press the “Finish” button to create the EDS file and store
these setting in the I-7242D. You can find the EDS file “MBDNS_x.eds” in the path of
DNS_MRU.exe.
6.The relation of application and assembly objects
The components of Assembly Objects
Example : (one DO device、one DI device、one AO device、one AI device)
In this example, apply four Modbus devices in the system.

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