Introduction to the Profinet Gateway
The PN1-D25P Series is a Profinet gateway that converts Profinet protocol to Modbus RTU. This gateway is used to map Modbus data to Profinet, enabling seamless integration of Modbus devices with Profinet-based systems. By utilizing the GSD file for integration, the gateway allows for easy read/write operations to Modbus devices without the need for programming. Configuration is quick, and data can be transmitted directly to the PLC.
The gateway provides one RS485 and one RS422 (RS485 compatible) interface, each supporting up to 32 command nodes, with a total of 64 command nodes. The PN1-D25PH model includes two RJ45 Ethernet ports, offering switch functionality. All Modbus commands are loaded as modules, with a clear memory-mapping relationship between Profinet and Modbus, which can be queried directly in STEP 7 or TIA Portal software. Status bytes can be loaded to monitor the connection status of Modbus devices in real-time.
This tutorial will guide you through the steps to load the Profinet gateway device using TIA Portal
TIA Portal Device Loading Tutorial
2.1 Preparation Before Connection
Prepare the required XML file, such as: GSDML-V2.3-EBYTE-PN1-D25-20241025.xml.
Connect the 24V DC external power supply to the module and power it on. Before powering up, ensure that the positive and negative terminals of the power supply are correctly connected.
Use Ethernet cable to connect the module to the Profinet port of the PLC controller, ensuring that both devices are on the same network segment.
2.2 Adding the GSDML File in TIA Portal
Open TIA Portal and go to the "Options" menu, then select Manage General Station Files (GSD).
Click Add GSDML File, navigate to the folder where the GSD file is stored, select the folder, and the software will automatically scan for available GSD files. Once found, check the box next to the required GSD file and click Install.
After the installation is complete, click Close to finish. The device is now ready for configuration.
2.3 Adding the Profinet Gateway Device to the Project
Create a New Project or open an existing one. If starting a new project, add the controller device first. Then, go to the device configuration view to add the appropriate I/O modules. Double-click on the module to add it to the project.
2.In the Network View, perform the device configuration and ensure the proper connections are made between devices.
3.In the Device View, locate and select the newly added device. Double-click on the module to open the General Configuration window. Here, you can modify the IP address and device name to match those on the module itself, or configure the IP address directly on the device.
You have now successfully added the Profinet gateway to the project in TIA Portal.
This guide provided a step-by-step process for loading the PN1-D25P Profinet Gateway into a TIA Portal project. In the next tutorial, we will cover the configuration of Modbus communication parameters for the Profinet gateway. Stay tuned for more!
