Features

The I-7232D 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 .

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: 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


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

Code	Name	Description
01	Read Coil Status	Read the ON/OFF status of discrete outputs in the slave
02	Read Input Status	Read the ON/OFF status of discrete inputs in the slave
03	Read Holding Registers	Read the binary contents of holding registers in the slave
04	Read Input Registers	Read the binary contents of input registers in the slave
06	Preset Single Register	Preset an integer value into a single register
15	Force Multi Coils	Forces each coil in the sequence of coils to either ON or OFF
