  • Page 5: Introduction

    1. Introduction CAN (Controller Area Network) bus is a serial communication interface, which is highly fault-tolerant even in harsh environments with noise. Therefore, there is often a need in the industry to convert interfaces such as RS -232, RS-485, RS-422 or USB to CAN interface for communication, so CAN converters are developed.

    1.2 Communication Mode Description The CAN converter supports three communication modes with Normal mode, Pair connection mode and Listen only mode as below descripption. In addition, please refer to section 3.4 for the setting method of the communication mode. If you need to use the COM port software during the test, please refer to section 5.7.
  • Page 13 In addition, if the customer only needs to exchange CAN messages with the CAN device through the CAN converter (for example: I-7530), and does not need to know the UART command string on the UART side, the VxCAN Utility can be used to achieve this requirement.

  • Page 14: Pair Connection Mode

    1.2.2 Pair Connection mode As the name suggests, this mode is designed to use two CAN converters for pair connection. The main purpose will transfer the interface from UART to CAN, and then transfer again the interface from CAN to UART, so that the interface conversion effect can be achieved without modifying the program of the field device as below figure .

  • Page 90: Parameter Description

    5.4.2 Parameter description The Bit Timing register of MCU contains 6 kinds of parameters, namely BPR, SJW, PRS, PHS2, PHS1 and SMP as below table: Table: Bit Timing Register Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 register...
  • Page 91 The formula as below: Number of Time Slices (TQ) = System Clock (Hz) / CAN Baud Rate (bps) For example: when the system clock is 20MHz and the CAN baud rate is 40K bps, the number of time slices (TQ) is 20(MHz) / 40(Kbps) = 500, that is to say that one bit of the time width Tbit is divided into 500 time slices in the CAN converter, and these time slices are allocated to Tsyns, Tprs, Tphs1 and Tphs2.
  • Page 92 In addition, when Tbit is fixed at 500, the maximum value of (4 + PRS + PHS1 + PHS2) is limited to 25, and the maximum value of BRP in the register Bit Timing 1 i s 63, so (4 + PRS + PHS1 + PHS2) will be in the range of 8~25, and (BRP + 1) will be in the range of 20~62, that is to say, the range of BRP will be in the range of 19~61.
  • Page 93 Therefore, if PHS1 is 7, then PRS will be 2. Next, if PHS1 and PRS are brought into the formula of (4 + PRS + PHS1 + PHS2) = 20, then PHS2 = 20 - 4 - 2 - 7 = 7. That is to say, the user can calculate the value of BRP from the number of time slices included in the time width of one bit, and calculate the values of PRS, PHS1 and PHS2 from the sampling point.

  • Page 94: Example Description

    5.4.3 Example description If the user want to use the user-defined CAN baud rate is 40K bps and the sampling point is 60%, because the CAN baud rate is greater than 12Kbps, the clock mode needs to be set to 1. However, when Clock Mode is set to 1, the MCU will use X2 mode, which means the system clock is 20MHz.
  • Page 95 If we fix (4 + PRS + PHS1 + PHS2) to 20, the BRP value is: / (BRP + 1) = (4 + PRS + PHS1 + PHS2) * TQ  500 / (BRP + 1) = 20  500 / 20 = (BRP + 1) = 25 ...
  • Page 96 4. Generally, both SJW and SMP are set to 0. Among them, when SMP is 0, it will be sampled once, and when SMP is 1, it will be sampled three times, and the sampling time interval must be greater than 1/2 Tscl period, and the final result is determined by a majority of three values.

  • Page 97: Can Id Filter Setting

    5.5 CAN ID filter setting The CAN converter can be set to filter the CAN messages of some CAN IDs, so that these CAN messages will not be transmitted to the RS -232/485/422/USB port. If the user want to enable this function need to adjust parameters such as acceptance code (ACC) and acceptance mask (ACM).

  • Page 98: Application Of Pair Connection Mode

    5.6 Application of Pair Connection mode The pair connection mode usually requires two identical sets of CAN converter modules. For example, when two sets of I-7530s are set to pair connection mode, one set of I-7530s will convert RS-232 commands into CAN messages and transmit them, while the other set of I-7530s will transmit CAN messages to RS-232, and the setting of each application will be explained as below.
  • Page 99 Communication description: For example, if device 1 sends 7 bytes of data ""1234567"" to I-7530 module #1, I- 7530 module #1 then forwards it to I-7530 module #2, and finally I-7530 Module #2 will send to the COM port of Device 2, and Device 2 will receive the data ""1234567"". The CAN ID in the above picture needs the user to set a fixed CAN ID, and the "Fixed CAN ID"...
