4.How to Start
Select DCON AI/AO/DI/DO
modules for users’ application
Configure these DCON modules
by using the DCON Utility
Connect these DCON modules
with the COM2 of the I-7231D
Use the CAN Gateway Utility to
configure the I-7231D and
create an EDS file for the
present state
Apply the EDS file for CANopen
master interface and run the I-
7231D on the CAN network
Select the necessary
ICPDAS I-7000/I-87
K
IO modules for you
r
CANopen application.
Configure the RS-485 baud
rate, checksum, module
address, data format and
type code of the IO modules
by using the DCON Utility.
1. Power off the I-7231D
2. Connect these DCON modules
with the COM 2 of the I-7231D.
3. Connect the COM1 of the I-
7231D with the PC’s COM port
via the RS-232 cable, CA0910F.
4. Wire the Init* pin and Gnd pin,
and then power on the I-7231D.
5. Execute the CAN Gateway Utility
to configure the communication
parameters of the I-7231D and
establish the EDS file.
After finishing the configuration of
the I-7231D and creation of the
specific EDS files, turn off the I-
7231D, remove the wire between
the Init* pin and Gnd pin, and turn
on the I-7231D.

5. Configuration Installation
Step1: Install the CAN Gateway Utility into your PC. Users can get the setup file from
the web site http://www.icpdas.com/download/index.htm or the product CD in the
path of “/Napdos/ iCAN/CAN_Gateway_Utility/.
Step2: Before running the CAN Gateway Utility, the DCON modules hanged on the
COM2 of the I-7231D need to be configure firstly. The following procedure may be
useful for DCON modules configuration.
Connect the PC RS-485 COM port with the RS-485 port of the one of the
DCON modules. If there is no RS-485 COM port on your PC, the RS-232/RS-
485 converter, I-7520, may be needed.
Power on this DCON module. And, configure it follow the steps described in
the quick start of the DCON Utility on-line Help.
Afterwards, power off the DCON Module, and disconnect this DCON module
with the PC RS-485 COM port.
Repeat the first three steps until all DCON modules have been configured.
After finishing the configuration, please connected the COM1 of the I-7231D with
the available COM port of your PC. Also, connect the configured I-7000/87K modules
with the COM2 of the I-7231D. The architecture is displayed in the following figure.
Step 3: Turn off the I-7231D firstly. Connect the INIT* pin and the GND pin on the I-
7231D. Then, turn on the I-7231D.
I-7231D CPS/DCON Quick Start User Guide (Version 1.1,Oct/2004, I-7231D) ------ 5
Step 4: Run the CAN Gateway Utility.
Step 5: The first screen of the Utility would be displayed as follows.
Step 6: Press the “Connect” button to connect the CANopen gateway. Then the “Com
Port Scan Parameter Setting” dialog will pop up as follows. Please set the proper
value for the RS-485 communication parameters. These parameters need to match
with the DCON modules parameters. Then, press the “OK” button to begin the
modules scans.
Step 7: When the DCON modules have been scanned, the scan result will be
compared with the parameters stored in the EEPROM of the I-7231D. If any difference
has been detected, the warning message will pop up as follows.
Because the default connected modules are I-7012, I-7021, I-7053 and I-7057. If
uses connect the I-7231D at first time with any different I/O module described above,
the “Some EEPROM Data is Error!” warning message may pop up. In this case, the
I-7231D CPS/DCON Quick Start User Guide (Version 1.1,Oct/2004, I-7231D) ------ 6
default value will be shown on each parameter setting field. Otherwise, the last setting
value will be displayed on each parameter setting field.
Step 8: Click the “CAN Channel” button so that the CAN bus configuration information
will be given. Then, users can set the necessary CAN bus communication information.
Afterwards, click the “Setting” button to finish the CAN parameter setting. The CAN
Parameter Viewer frame on the right hand side indicates the parameter setting result.
After clicking the “Setting” button, users can see that the each field of the CAN
Parameter Viewer frame is changed to the value configured in the CAN Parameter
Setting frame on the left hand side.

Step 9: Click the “COM2 ” button to configure the RS-485 parameters of the
CPS_DCON gateway. After finishing the configuration, click the “Setting” button to
save the setting result, and click “Build EDS File” button to the next.
Step 10: The two fields, “description” and “create by”, can help user to do some notes
in the EDS file. If these two fields are empty, the “ICPDAS CANopen slave/DCON
master Gateway” and “ICPDAS” will be used as the default value when creating the
EDS file.
Step 11: User can click the “PDO Information”, “Device Information “, and “Dcon
Information button to view the PDO objects, device profile and I-7000/87K
configuration information. These information dialogs are shown below.

If every thing is ok, click the “Finish” button to create an EDS file and save the related
information into the EEPROM of the I-7231D. Then, user can use this EDS on any
CAN master interface.
Step 12: Power off the I-7231D, and remove the wire between the Init* pin and GND
pin on the I-7231D. Then, power on the I-7231D. When the I-7231D has finished the
initialization, the RUN LED on the I-7231D will be flashed about twice per second, and
the I-7231D is into the NMT pre-operational state. For more information about the
CANopen system and CANopen communication set, please refer to the I-7231D user
manual.
