Profibus to ModbusTCP Gateway Module (XD-ETHPB20)It is widely used in the field of industrial automation. For example, the sensor data in the Profibus network can be converted into the ModbusTCP protocol to achieve real-time monitoring and remote control of the data. This article introduces how to useProfibus to ModbusTCP Gateway (XD-ETHPB20)The module will haveProfibus_DP protocolMa Bao is connected to the host computer to achieveModbusTCP Communication

Profibus to ModbusTCP moduleFeatures and benefits:

supportProfibus DP MasterModbusTCP Master/SlaveFunction; built-inProfibus DPModbusTCP Protocol, achieving seamless conversion of protocols; supporting various network configuration methods such as fixed IP, DHCP automatic IP acquisition, etc.; supporting Web configuration pages, easy to operate, easy for users to get started quickly; with good stability and reliability, suitable for various industrial environments.

Profibus to ModbusTCP GatewayThe module connects the motor protector (M-Protector) to communicate with the host computer, which mainly involves hardware connection, configuration settings, and data interaction. The following is a detailed process description:

1. Hardware Connection

1. Make sure the interfaces match: First, checkProfibus to ModbusTCP Gateway Module, motor protector and whether the interface of the host computer matches, including cable type, interface type, etc.

2. Physical connection: Use appropriate cables toProfibus to ModbusTCP Gateway ModuleConnect it to the motor protector, and ensure that the connection between the gateway module and the host computer (such as PC, PLC, etc.) is also correct.

2. Configuration Settings

1. Import GSD file:

WillProfibus to ModbusTCP Gateway ModuleThe GSD file is imported into the configuration software of the host computer. The GSD file contains the device description information of the gateway module, which helps the host computer to correctly identify the gateway module.

In the configuration software of the host computer, choose to import the GSD file and install it according to the software prompts.

2. Add module equipment:

In the configuration software of the host computer, add the Profibus to ModbusTCP gateway module device and set its related parameters, such as IP address, device name, etc.

Make sure these parameters match the actual configuration of the Gateway module.

3. Configure ModbusTCP parameters:

In the configuration software of the gateway module, set the ModbusTCP communication parameters, such as baud rate (for TCP protocol, this parameter is actually the port number or IP address and port combination of TCP connection), data bit, stop bit and check mode, etc. These parameters need to match the communication parameters of the motor protector.

Note that since ModbusTCP is based on the TCP/IP protocol, it is not necessary to set traditional serial communication parameters such as baud rate, but network parameters such as IP address and port number.

4. Add data mapping:

In the configuration software, add data mapping relationship to map the data address of Profibus protocol with the data address of ModbusTCP protocol. In this way, when the host computer accesses a specific address through ModbusTCP protocol, the gateway module can convert it into a data request of Profibus protocol and send it to the motor protector.

Ensure data mapping accuracy to avoid data misalignment or loss.

5. Download configuration:

Download the configured parameters to the Profibus to ModbusTCP gateway module and restart the device to make them take effect.

3. Data Interaction

1. The host computer sends instructions:

The host computer sends data read and write requests to the Profibus to ModbusTCP gateway module through the ModbusTCP protocol.

2. Gateway module conversion:

After receiving the data request of ModbusTCP protocol, the gateway module converts it into the data request of Profibus protocol and sends it to the motor protector.

3. Motor protector response:

After receiving the data request of the Profibus protocol, the motor protector performs the corresponding operation and returns the result to the gateway module.

4. Gateway module reconversion:

The gateway module converts the response result of the motor protector into the data format of the ModbusTCP protocol and sends it to the host computer.

5. The host computer receives data:

After receiving the data of ModbusTCP protocol, the host computer parses and processes it to obtain the required information.

Through the above steps,Profibus to ModbusTCP Gateway ModuleThe motor protector can be successfully connected to the host computer to achieve data interaction between them. In practical applications, it is also necessary to pay attention to issues such as the compatibility of communication protocols, the compatibility of equipment, and the accuracy of communication parameters.
