Features
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:
- Select Modbus RTU devices for users' CANopen application
- Set the Modbus RTU devices 10 parameters into I-7232D by CAN_MRU Utility
- Configure the I-7232D and create EDS file
- Apply EDS file to CANopen application
- Implement the I-7232D in CANopen network
