Bộ chuyển đổi CANopen sang Modbus RTU ICP DAS I-7232D


I-7232D applicationThe I-7232D CANopen to Modbus RTU Gateway is an ICP DAS CAN bus product. The device allows a CANopen master to access the Modbus slave devices on some Modbus RTU network. Modbus RTU protocol is a kind of application protocol based on RS485 network. This gateway provides an easy way to connect Modbus RTU devices with CANopen network These Modbus RTU devices may be a PLC, a Modbus RTU sensor, or ICPDAS M-7000 series modules. We also provide the utility software for users to configure the I-7232D,s parameters and build the EDS file for the CANopen master interface. Users can easily apply Modbus RTU devices in CANopen applications wit the I-7232D.

The I-7232D Utility helps users to configure the devices, and has following features:

  • Support CANopen node ID, baud rate setting

  • Provide Modbus RTU parameters setting

  • Display Modbus RTU devices configuration

  • Show CANopen application objects configuration

  • Produce EDS file Dynamically



The simple steps about how to use CPS_DCON gateway are described as follows:

  1. Select Modbus RTU devices for users' CANopen application

  2. Set the Modbus RTU devices 10 parameters into I-7232D by CAN_MRU Utility

  3. Configure the I-7232D and create EDS file

  4. Apply EDS file to CANopen application

  5. Implement the I-7232D in CANopen network
