I-7232D

The 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.

Utility

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

Usage

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

Modules Support

Only the following Modbus RTU commands are supported by the gateway.
