CANopen Slave Device

Introduction

This user guide introduces the user how to implement the

CAN-8123/CAN-8223/CAN-8423 into their applications in a quick and easy

way. Therefore, it only provides the basic instructions. For more detail

information about the CAN-8123/CAN-8223/CAN-8423, please refer to the

CAN-8123/CAN-8223/CAN-8423 user manual in the product CD or download

it from following web site:

Power and CAN Connection

The CAN-8123/CAN-8223/CAN-8423 CAN connector is standard 5-pin screw terminal

connector. Uses can connect it directly with any other standard male 5-pin screw terminal.

Take a note that the CAN-8423 power pin of CAN connector is useless. Therefore, users need

to give CAN-8423 power by using power connector. Please refer to the CAN-8423 Hardware

Structure described before.

Terminal Resistance

In order to minimize the reflection effects on the CAN bus line, the CAN bus line has to be

terminated at both ends by two terminal resistances. The CAN-8123/CAN-8223/CAN-8423

has the 120Ωterminal resistance inside. The JP2 of the CAN-8123/CAN-8223 and the JP1 of

the CAN-8423 is for terminal resistance. Their position and jumper status are shown in the

following figure.

Install CAN Slave Utility

Step1:Download the CAN Slave Utility setup file from the web site

http://www.icpdas.com/download/index.htm

or CD-ROM disk following the path:

“/CANopen/Slave/CAN-8x23/Utility/Setup.exe”

Step 2: Execute the CAN_SL_Setup.exe file to install the CAN Slave Utility.

CAN-8123/ CAN-8223 Configuration (Off-line mode)

Step 1: Select “Application Layer” to “CANopen”. Then, select the “Setting status” to offline.

Here, assume that users’ CAN slave device is CAN-8223 with node id 123 and baud rate

1000Kbps. Fill the correct value of users’ CAN-8223 node id and baud in the “NODE ID” and

“CAN Baud rate” filed. Then, select the “Slot Number” to “2 Slot”.

Step 2: Assume that users plug the I-8024 and I-8042 slot modules in the slot 0 and 1

respectively. Click the slot 0 icons shown in the “CAN Slave Device Situation” frame. Select

CAN-8123/CAN-8223/CAN-8423 Quick Start User Guide (Version 2.0 July/2007) --------- 3

8024 in the list box, and click button “Apply Module” to save the configuration. After finish the

configuration, users can slip the mouse point to the slot module in the “CAN Slave Device

Situation” frame. Afterwards, add another module I-8042 in the slot 1 by following the method

described before. When all slot are configured, click “Save Setting” to go on the next.

Step 3: Users can check the default settings for each slot module by clicking this module. Or

move the mouse pointer on the slot module to see the module name and module information in

the “Module Information” frame.

Step 4: The two fields, “description” and “create by”, can help users to do some notes in the

EDS file. If they are empty, the “ICPDAS CANopen I/O Slave Device” and “ICPDAS” will be

CAN-8123/CAN-8223/CAN-8423 Quick Start User Guide (Version 2.0 July/2007) --------- 4

used for the default value. Users can also click on the “PDO Information”, “Device Information “,

and the “Slot Module Information” button to view the PDO objects, device profile and slot

module information. If everything is ok, click the “Finish” button to create the EDS file.

Note: If users use off-line method to get the EDS file, the objects which are used to record the

input/output range of the analog modules will be described to default value in the EDS file.

However, the I-87K slot modules hold the input/output range parameter settings in their own

EEPROM. It may cause the mismatch between real input/output range setting and EDS file. By

the way, II-8KCPSx needs to configure the input/output range settings by using CANopen

SDO protocol. For more detail, please refer to the section 5.5 in CAN-8123/CAN-8223/

CAN-8423 user manual.

CAN-8423 Configuration (On-line mode)

Before using the CAN Slave utility, please make sure that you have connected COM1 of

the CAN-8423 with the available COM port on your PC. The architecture is displayed in the

following figure. In this example, the CAN-8423 will be used, and slot modules, I-87057,

I-87057, I-87024 and I-87017H are plugged in the slot 0, 1, 2, 3 respectively (If users don’t

have any slot module, they can also follow this demo to configure their CAN-8423. But some

situation or information relative with slot modules will be difference).

Step 1: Turn off the CAN-8423. Set the “Baud” rotary switch of CAN-8423 to 9 for

configuration mode. Then Turn on the CAN-8423.

CAN-8123/CAN-8223/CAN-8423 Quick Start User Guide (Version 2.0 July/2007) --------- 5

Step 2: Use the “ID” rotary switch and “Baud” rotary switch to set the baud rate of CAN-8423.

The node ID is useless when the value exceeds the 7F (127 for decimal format) because of

the CANopen spec definition. The relationship between the rotary switch value and practical

baud rate is displayed in the following table. Here, use ID 123 and baud rate 1000Kbps for the

demo. Therefore, set the “ID” rotary switch to “7B” (7B=7*16+B=112+11=123) and “Baud”

rotary switch to 7.

Rotary Switch Value Baud rate (K BPS)

0 10

1 20

2 50

3 125

4 250

5 500

6 800

7 1000

Step 3: Execute the CAN_SL.exe file, and the figure will be displayed. Select a PC COM port

to connect the CAN-8423. Here, use PC COM 2 for this demo. Therefore, users need to click

the “PC COM Port” list box, set it to COM2, and click button “Connect” to connect the

CAN-8423. Afterwards, the utility tool will get the information stored in the CAN-8423.

Step 4: Users can move the mouse pointer to the slot of CAN-8423 shown in the “CAN Slave

Device Situation” to get the module information of this slot module.

CAN-8123/CAN-8223/CAN-8423 Quick Start User Guide (Version 2.0 July/2007) --------- 6

Step 5: Click the slot module 3. Here, select the output range to -10.00V~+10.00V in the list

box of “Module Configuration” frame for example. Because the feature of I-8024 slot module,

each channel output range will be changed together after users select the output range of one

channel. Click “Set” button to store the parameter setting. If all of slot module configurations

are finished, click “Build EDS File” button to go on the next step.

Step 6: Afterwards, users can see the “EDS File Information” window, and fill the

“Description” and “Create by” filed for the EDS file. Also, users can see the CANopen objects

CAN-8123/CAN-8223/CAN-8423 Quick Start User Guide (Version 2.0 July/2007) --------- 7

information and modules information by click the buttons. Please refer to the step 6 in the

off-line setting described before.

Note: The CAN-8423 can also create the EDS file by using off-line mode, and set the analog

input range or analog output range by using the CANopen SDO protocol. For more detail,

please refer to the section 5.5 in CAN-8123/CAN-8223/CAN-8423 user manual.
