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，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. |

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
