Profinet communication settings between ABB robots and Siemens PLCs

1、 Introduction

In the field of modern industrial automation, communication between robots and PLCs is an important link in achieving efficient and precise production. The Profinet communication setting between ABB robots and Siemens PLCs is the key to achieving seamless integration between the two. This article will provide a detailed introduction to the Profinet communication setup steps between ABB robots and Siemens PLCs, aiming to provide readers with a comprehensive and in-depth guide.

2、 Overview of Profinet Communication

Profinet is an industrial automation communication protocol based on Ethernet, which supports high-speed data transmission and plug and play of devices. It is one of the widely used communication standards in the field of industrial automation. The Profinet communication settings between ABB robots and Siemens PLCs are based on this protocol.

3、 Profinet communication setup steps between ABB robot and Siemens PLC

Hardware preparation

Ensure that both ABB robots and Siemens PLCs support Profinet communication protocol.

Prepare necessary communication cables, such as Ethernet cables, etc.

Ensure that the network settings of ABB robots and Siemens PLCs are within the same local area network, i.e. have the same IP address range.

Setting up ABB robot end

Open the ABB robot’s teaching pendant and enter the control panel.

In the control panel, select the “Configuration” option, then go to “Theme” ->”Communication” ->”IP Setting” ->”PROFINET Network”.

In the PROFINET Network interface, set network parameters such as the IP address, subnet mask, and gateway for the ABB robot. Note that these parameters need to match the network parameters of Siemens PLC.

In the same interface, select Interface as WAN (if necessary) to ensure consistency with the robot’s public IP.

After clicking OK, the teaching pendant will prompt to restart. At this point, you can choose ‘No’ and restart uniformly after all configurations are completed.

Next, modify the PROFINET device name. In the control panel, go to “I/O” ->”IndustrialNetwork” ->”PROFINET” and modify the device name to match the PROFINET device name in the Siemens PLC configuration.

Finally, modify the communication byte length. In the control panel, go to “I/O” ->”PROFINET Internal Device” ->”PN_internalDivice”, and set the byte count to be consistent with the byte count set in the Siemens PLC configuration.

Settings for Siemens PLC end

Open the programming software for Siemens PLC (such as TIA Portal) and create a new project.

Add Siemens PLC hardware to the project and set its network parameters such as IP address, subnet mask, and gateway to ensure they match the network parameters of ABB robots.

In the network view, add ABB robot hardware. Find ABB’s GSD file (such as ABB BASIC V1.4) in the hardware directory and add it to the network view.

Assign a Profinet controller to the PLC and set the name and IP address of the Profinet IO device to ensure consistency with the ABB robot settings.

According to actual communication needs, add the length of communication data and set the PLC addresses for input and output. Here, taking the example of both input and output being 64 bytes.

Save the hardware configuration and download it to Siemens PLC.

Communication testing

Connect ABB robots with Siemens PLCs via Ethernet cables.

In the programming software of Siemens PLC, click the “Go Online” button to ensure that both the PLC and ABB robot display online status.

Conduct communication testing. Firstly, send data to ABB robots through PLC and observe whether the robots can receive the data correctly; Then, send data to the PLC through ABB robots and observe whether the PLC can receive the data correctly. If the data sent and received are consistent, it indicates that the Profinet communication between ABB robot and Siemens PLC has been successfully set up.

4、 Precautions

When setting up Profinet communication between ABB robots and Siemens PLCs, it is important to ensure that the network parameters of both are matched, including IP address, subnet mask, gateway, etc.

When setting the length of communication data and input/output addresses, adjustments need to be made according to actual needs to ensure the correct transmission of data.

When conducting communication testing, it is important to observe the transmission and reception of data, promptly identify and resolve issues.

5、 Summary

The Profinet communication setting between ABB robots and Siemens PLCs is the key to achieving seamless integration between the two. Through the introduction of this article, readers can learn detailed setting steps and precautions, providing reference for practical applications. In practical operation, adjustments and optimizations need to be made according to specific situations to ensure the stability and reliability of communication.
