CAN (Controller Area Network) is a serial bus system especially suited to structure intelligent industry devices networks and build smart automatic control systems. The following figure shows the application architecture for I-7530A modules. The PC can be the CAN host, monitor or HMI to access/control the CAN device through the CAN network by the I-7530A Converter. The programmable RS-232/485/422 device (For example: I-8411/I-8431/I-8811/I-8831/W-8031/W-8331/W-8731 embedded controller) can use the serial port to connect to the CAN network via the I-7530A module. In order to use the CAN network with traditional RS-232/485/422 devices, we provide a way to achieve this purpose. The I-7530A is designed to unleash the power of CAN bus via RS-232/485/422 communication method. It accurately converts messages between CAN and RS-232/485/422 networks. This module let you to communicate with CAN devices easily from any PC or devices with RS-232/485/422 interface.

Moreover, we expand the functionalities of I-7530A for some special application. In pair connection mode, I-7530A can be used to connect PC with other RS-232/485/422 devices at the same time. The application architecture may be as follows.

3000V isolation on CAN side
The CAN port of I-7530A is an isolated with 3000V isolation. This isolation can protect the local RS-232/485/422 devices from the damage signal coming from CAN network.

Watchdog inside
The I-7530A Watchdog is a hardware reset circuit to monitor the I-7530A’s operation status. When working in harsh or noisy environment, the I-7530A may be down by the external signal. The circuit may let the I-7530A to work continuously and never halt.

Power and Error indicator display
There are two indicators on the I-7530A.The power indicator can help user to check whether the I-7530A is standby or transmitting/receiving messages. The Error indicator will be turned on when some errors occur on the I-7530A.

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.

Features of CAN bus power meter:
  • Compatible with CAN specification 2.0A and B
  • Fully compatible with ISO 11898-2 standard
  • Support various baud rate from 10K bps to 1M bps
  • Jumper for 120 Ω terminator resistor
  • Software configurable CAN and RS-232 /422/485 communication parameters
  • Power, data flow and error indicator for CAN and RS-232/422/485
  • Watchdog inside
  • Provide the transparent communication between the RS-232/485/422 devices via CAN bus
  • Enable different RS-232/485/422 devices into an individual group in CAN bus network.

  • Setting for I-7530A communication mode (normal mode or pair connection mode)
  • It has a CAN message field which can display the receiving CAN messages in Decimal or HEX mode.
  • Can display the timestamp of each received CAN message.
  • Users can change the display mode, up-down, down-up or stop.
  • It can count the number of received CAN messages.
  • Data Log : It can save the CAN message as “ txt ” file.
  • Has CAN ID filter function.
  • Can send CAN message to CAN BUS according the defined interval time.

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.
