Internet communications using TCP/IP is increasing in the industrial sector. Using Ethernet for network in industrial area is appealing because the required cabling is already installed. The CAN-Ethernet Gateway 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 CAN-Ethernet Gateway 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 CAN-Ethernet Gateway 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 CAN-Ethernet Gateway .

Furthermore, I-7540D also can be used as Ethernet to CAN/RS-232/485 Device Server. The Device Server is an appliance that network enables any device with a serial communication port. By virtue of its independent operating system, protocol independence, small size and flexibility, Device servers are able to meet the demand of virtually any network-enable application. Most devices don't have network ports. I-7540D allows those devices to become connected to the network.

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-7540 just as them would access the PC's COM port. The block diagram of data processes in I-7540D is given as follows:


The PM-213x-CAN series power meter provides the CAN bus interface for users to easily gather the real-time power consumption information in their CAN applications. The PM-213x-CAN provides the Auto-Response mode which responses messages at regular intervals automatically. It makes the communication more efficient when collecting a lot of remote power information. The polling mode offers the precise information of every step required by the monitors. In addition, the PM-213x-CAN also owns the arbitration mechanism which can avoid data collision and error detection.

There are various communication interfaces among the CAN devices like PCI CAN board, Ethernet series and RS-232 series CAN module. According to different purpose of users’ projects, the users maybe need to choice different CAN products. Because of this situation, the programmer should develop different communication program to handle different CAN device. For example, the user should develop “Socket Client” to communicate with I-7540. When using I-7530, the users need “UART” technique to communicate with it. Nowadays, ICP DAS develop the Virtual CAN technique. The Virtual CAN driver is the excellent tool for users. It transforms whole CAN devices into Virtual CAN port. And then it generates Virtual CAN port like “VxCAN 1” or “VxCAN 2”. The users could send and receive CAN message by appointing the Virtual CAN port number. The users don't need to care about what kind of CAN device which is used.

InduSoft Web Studio is a powerful, integrated collection of automation tools that includes all the building blocks needed to develop modern Human Machine Interfaces (HMI), Supervisory Control and Data Acquisition (SCADA) systems, and embedded instrumentation and control application.

In order to apply the field bus communication by InduSoft software, ICP DAS provides several field bus components such as CAN, CANopen, DeviceNet and so on, in the InduSoft driver. By means of these drivers, you don't need to have the complex and abstruse background of these field bus protocols. Only few simple steps can finish the communication between your PC and the remote devices.
