1. Introduction

“Embedded Internet” and “Embedded Ethernet” are hot topics today. Nowadays the Ethernet protocol becomes the de-facto standard for local area network. Via Internet, connectivity is occurring everywhere, from home appliances to vending machines to testing equipment to UPS…etc. Using Ethernet for network in industrial area is appealing because the required cabling is already installed. The i-7540D from ICP DAS is a solution that enables CAN networks to be coupled together over the Internet/Ethernet, whereby remote monitoring and control is possible. The i-7540D controls networked communication and makes a transparent CAN-based application interface available to the user.

The device supports a transparent, protocol-independent transfer of the CAN messages, thus allowing its implementation into a wide range of possible applications. Furthermore, the i-7540D can be used with various higher layer CAN protocols (e.g. CANopen, DeviceNet or other proprietary protocols). The following figure shows the application architecture for the i-7540D.

1.3 VxComm Technology

The i-7540D is designed as a RS-232/RS-485/CAN to Ethernet Gateway. So it follows that they can be used to link these RS-232/RS-485/CAN devices to central computer as follows:

Figure 1-2: Application of i-7540D

Compared to the RS-485 network, these Ethernet network hubs are already in existence for system network. Therefore, the RS-232 devices can find the closest hub and link to the central computer with the help of the i-7540D. The Ethernet network is extremely popular and already existing for most applications, hence, this approach is a very successful. In general, it is more difficult to write a TCP/IP program than a COM 1/2 program. Therefore, the VxComm technology is

developed to simulate COM-ports of the i-7540D to become COM 3/4/5…/256 of the central computer. Then users can write a COM port program to link these

RS-232/RS-485/CAN devices and need not to concern themselves with any TCP/IP problem.

i-7540D CAN-Ethernet Gateway User’s Manual (Version 1.4, April/2008)

Page 9

In some factories, there are old systems still running and in case. These old systems only support COM port applications. Therefore, the Vxcomm technology can be used to upgrade these old systems to support Ethernet network. To recap, the VxComm technology is useful as follows:

z Provides a much easier interface for software programmers. z Keeps the old systems going without program modification

The block diagram of VxComm technology for the i-7540D is given as follows:

The VxComm technology can be used to simulate COM/CAN ports of the i-7540D to become a COM port of PC. With the help of VxComm driver, users can access the remote COM/CAN ports of the i-7540D just as them would access the PC’s COM port.

2.3 Terminator resistor settings

In order to minimize reflection effects on the CAN bus line, the CAN bus lines have to be terminated at both ends by two terminal resistances. Based on the ISO 11898-2 spec, each terminal resistance is 120Ω (or between 108Ω~132Ω). The length related resistance should have 70 mΩ/m. Users should check the resistances of their CAN bus, before they install a new CAN network as figure 2-4.

Figure 2-4: Terminator resistor

Moreover, to minimize the voltage drop on long distance, the terminal resistance should be higher than the value defined in the ISO 11898-2. Table 2-4 may be used as a reference.

2.4 LED Indication

The i-7540D provides the Converter function between the Ethernet port and the RS-232 & RS485 & CAN port. It can handle both 11-bits and 29-bits ID format according to whether it is a CAN 2.0A or 2.0B. It also provides some LEDs to indicate to users what situation the i-7540D is in.

2.4.1 Power LED

There is a red indicator-LED in the i-7540D as follow:

 Firmware is running: flashing red

The default shipping of i-7540D will be firmware inside, so the red

indicator-LED of i-7540D will be ON 0.5 second then OFF 0.5 second periodically.

i-7540D CAN-Ethernet Gateway User’s Manual (Version 1.4, April/2008)

Page 18

2.4.2 CAN bus indicator LED

The i-7540D includes three single-color LED displays to indicate the status of module, network and I/O device. They are ER LED (it is red), TX LED (it is green), and RX LED (it is red). The Indicators assist maintenance personnel in quickly identifying a problem unit. The LED test is to be performed at power–up. When the CAN communication events occur, these indicators will be triggered to glitter with different conditions.

z ER LED This LED provides device status and indicates whether or not the device is operating properly. Table 2-6 shows the conditions of ER status. Therefore, when the device is operated normally, the ER-LED must be turned off. If this led flashing

red, users can use the “99S” command, in section 4.5, to read the status of the i-7540D.

Table 2-6 ER-LED conditions

Condition Description

Off Device is normal; no error occurs

Red Device has unrecoverable fault

Flashing red Device has recoverable fault.

To recover:

Reset device or perform error recovery

z TX LED This LED indicates the status of message transmitted. Table 2-7 shows the conditions of TX status. Therefore, when the device transmits messages to the CAN bus, the TX-LED is normally flashing green.

Table 2-7 TX led conditions

Condition Description

z Overview z Installing the VxComm Driver z Adding a i-7540D and configuring the VxComm Driver z Removing a i-7540D z Uninstalling the VxComm Driver

5.1 Overview

The VxComm (Virtual Comm) Driver and VxComm Utility are very easy to install and use. The first thing to do is to find the installation file in the included CD. The directory is:

¾ 8000cd:\\napdos\7188e\tcp\vxcomm\driver(pc)\nt\

(for Windows NT 4.0) or ¾ 8000cd:\\napdos\7188e\tcp\vxcomm\driver(pc)\2k\

(for Windows 2000, Windows XP).

This document shows how to install and configure the driver correctly. The first part instructs users how to install the software. The second part shows how to add an i-7540D server and configure a COM port. Finally, the third part teaches you how to remove an i-7540D.

i-7540D CAN-Ethernet Gateway User’s Manual (Version 1.4, April/2008)

Page 92

5.1.1 Architecture

The VxComm Driver creates COM port(s) and maps them to the COM port(s) of the i-7540D. The user's RS-232 client programs need only to change to the different COM port to access the serial devices that are allocated to the Internet or Ethernet network via the i-7540D.

i-7540D CAN-Ethernet Gateway User’s Manual (Version 1.4, April/2008)

Page 93

5.1.2 Ports mapping

Vxcomm Driver/Utility supports Port 1 to Port 3 in accessing COM1 to COM3 of the i-7540D. Another Port I/O is designed to access the I/O boards mounted on i-7540D, but it doesn’t use now. With the help of the VxComm Driver/Utility, uses can map remote COM port to become a virtual COM port of PC. One PC can control maximum number of 256 COM ports (including COM1 and COM2).

5.2 Installing the VxComm Driver

Step 1: The installation software can be obtained from the following location.

z http://ftp.icpdas.com/pub/cd/8000cd/napdos/7188e/tcp/vxcomm/

driver(pc)/

z 8000cd:\\Napdos\7188e\TCP\vxcomm\driver(pc)\ Please choose the version that suits your Windows operation system.

z vxcomm2K_vNNNNN.exe for Windows 2000/XP z vxcommnt_vNNNNN.exe for Windows NT

z vxcomm98.exe for Windows 98

Step 2: Go the where you download the installation file, and then double-click

the file in Windows to execute it.

Page 95

Step 3: Select the “Yes, …” option and click the Finish button to restart your

computer.

Step 4: After rebooting the computer, the VxComm Utility will ask you to

configure the virtual COM port(s). Please refer to the next section (5.3) for more information.

5.3 Adding an i-7540D and configuring the VxComm Driver

Step 1: Obtain the IP address of the i7540D. The MiniOS7 Utility can help you in

obtaining the IP address of the i-7540D.

Note: The default IP address of the i-7540D is 192.168.255.1

Step 2: From the Winsows Start Menu, go to Program/7188e/Vxcomm2K/ and

locate the VxComm Utility.

Step 3: Before adding an i-7540D, ensure that the Check Duplicated IP and

Connect to Server options are both checked. Type the IP address of the i-7540D and then click the Add Server button to add a new server.

i-7540D CAN-Ethernet Gateway User’s Manual (Version 1.4, April/2008)

Page 97

Note:

z Check Duplicated IP option

This option checks whether the IP address is already listed in the server window (left hand window). It is automatically checked by default. The following alert will be displayed if an IP address is duplicated.

z Connect to Server option

This option connects to the i-7540D and retrieves the name of device before adding it to the server window (left hand window). It is automatically checked by default. The following alert will be displayed if the Connect to Server option is not checked before clicking the Add Server button. Choose the correct i-7540D Model Number and then click the OK button (Here the

i-7540D model number is 7186E3).

z Timeout (ms) field

This timeout value is used for Connecting, disconnecting and sending/receiving data in the VxComm Utility, and is used for Connecting and Disconnecting in the VxComm Driver.

z Command Port field:

By default, the Command/Configuration TCP port is 10000. If you change the setting of μPAC-7186E, then you must assign the correct one in this field to let the VxComm Utility and Driver to get access to the device.

i-7540D CAN-Ethernet Gateway User’s Manual (Version 1.4, April/2008)

Page 98

Step 4: And then it will display the name of “7186E3” and it’s IP. Select one of

the i-7540D devices and configure the virtual COM port(s) by double clicking "Port 1", "Port 2" or “Port 3”.

Step 5: Select an appropriate COM port number, and then click the OK button.

Note:

z Re-assign COM number for all subsequent ports option

This option automatically sequentially assigns the ports with the available COM port numbers.

z Use 7188E/8000E current setting (Fixed Configuration)

If using this Port Configuration function, you will not be able to dynamically change the Baud Rate and data format.

button to configure the server options.

Step 7: Enter the new configuration settings. The new settings will replace any

text already in the Server Options window text boxes. Click the OK button to save the new settings.

Notes:

z Keep Alive Time (ms) field:

After connecting to the μPAC-7186E, the VxComm Driver will automatically and periodically send commands to keep the i-7540D alive. The timer will be reset after each send/receive command/data success. The Keep-Alive mechanism will not work until the next timeout. The default setting of Keep-Alive time is about 7000 ms. Its recommended setting is (i-7540D’s System Timeout * 1 / 3) or smaller value.

z Connection-Broken (ms) field:

The VxComm Driver will try to re-connect if the connection is broken. When the client is sending a message to the μPAC-7186E, the Internet (TCP/IP)

layer may respond with a “Disconnect” event to the VxComm Driver if it fails to send the message after 20 seconds or more. Users can set a smaller Connection-Broken time (for example: 10000 ms) to force the VxComm Driver to re-connect again and get a quicker response.

If the connection has no sending/receiving signal before the Connection-Broken time has timed out, the connection will be marked as broken. The VxComm Driver will also re-connect it again. Thus, the Keep-Alive Time should be smaller than the Connection-Broken time to make the connection come on-line.

The default System Timeout (/STxxx) value of the i-7540D is about 300 seconds. After client programs have connected to the μPAC-7186E, clients have to send command to keep the i-7540D alive before it times out, otherwise the μPAC-7186E will reset itself and clients will have to reconnect to the i-7540D again.

Users can set the Keep-Alive Time and Connection-Broken time to 0 to disable this mechanism. The System Timeout will have to be set to 0 to disable the reset mechanism.

z Connect Timeout (ms) field:

The timeout value will be passed into MS TCP/IP driver for reference when connecting and disconnecting.

z Command TCP Port field:

By default setting, the i-7540D use TCP port 10000 as the Command / Configuration port. If you change the setting of i-7540D, you must assign the correct one in the field. So the VxComm Driver can connect to the right TCP port.

This TCP port is used to configure the Baud rate, data format, CTS/RTS control mode and Break, etc.

z Port7000 Port field:

By default setting, the i-7540D use TCP port 9999 as the Port7000 port. This TCP port is reserved.
