The I-7232D is one of ICP DAS CAN bus products. 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. Therefore, 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, ICPDAS M-7000 series modules and so fourth. In addition, we also provide the utility software for users to configure the I-7232D，s parameters and build the EDS file for CANopen master interface. Users can easily apply Modbus RTU devices in CANopen applications with the I-7232D.
