I-7232D
CANopen / Modbus RTU Gateway

 
 
     
 
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¡As parameters and build the EDS file for CANopen master interface. Users can easily apply Modbus RTU devices in CANopen applications with 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
 

   
 
   
 

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