Introduction

I-7530A-MR-FD supports Modbus RTU protocol on RS-232/422/485 port, it is a Modbus RTU to CAN converter, it supports CAN2.0A/2.0B and CAN FD, and provides user-defined CAN Bus communication baud rate (arbitration field: 10Kbps to 1Mbps, CAN FD data field: 100Kbps to 10Mbps).
And with the special designed firmware, beside normal received CAN message buffer, it offers special memory space to save up to 100 kinds of CAN messages which are urgent and must be processed immediately. The feature helps the PLC, HMI and SCADA to use Modbus RTU function code 3,4,16 to access CAN devices in an easy way.

  • Modbus RTU Slave/CAN FD Master Mode
    In Modbus RTU mode, it allows a Modbus RTU master to communicate with CAN devices on a CAN network. The following figure shows the application architecture of this mode.

  • Modbus RTU Master/CAN FD Slave Mode
    In the Modbus Master mode, it allows many Modbus RTU slaves to communicate with CAN devices on a CAN network. The following figure shows the application architecture in this mode.

  • Pair-Connection Mode
    In pair-connection mode, this module provides the pair connection and transparent communication between the RS-232/485/422 devices via CAN bus. The application architecture may be as follows.

  • UART Switch Mode
    In UART Switch mode, the I-7530A-MR-FD can convert CAN messages to UART ASCII or convert UART ASCII to CAN messages.

Application

• Control System
• Building Automation
• Factory Automation
• Distributed data acquisition
