In recent years, robotic arms have appeared more and more frequently in social life and public attention. For example, in industrial assembly workshops, mouth and nose swabs are automatically collected for nucleic acid testing ......
In a workshop, the upper computer software in the central control room controls the operation of the robotic arm, and the upper computer supports the modbus protocol; As the master station of PROFINET, the KUKA robotic arm adopts different communication protocols between the two, and how to control and collect the KUKA robotic arm through the host computer has become a difficult point in the project.
Beijing Jiyuan Automation provided a solution for the first time: the communication between the host computer and the KUKA robotic arm was realized through Profinet SL**e to Modbus RTU Master.
On the Profinet side, the gateway works as a Profinet-IO device and uses slots and sub-slots for data exchange. Provide the customer with a GSDML file for this gateway by loading the GSDML file and configuring the PROFINET network; On the serial side, the device can be used as either a Modbus master and a user-defined protocol. The mapping of Profinet-IO and serial port data is completed by the configuration software, and the exchange of Profinet-IO network data and serial network data is completed through the gateway.
Project realization
The software package is configured on the KUKA robotic arm, and the robotic arm is configured as the PROFINET master on WorkVisual.
Load the xml file of ET001.
Configure the mapping area.
Debug the host computer software.
Summary
The project uses the PROFINET to Modbus RTU gateway ET001 provided by Beijing Jiyuan Automation to simply and quickly break through the communication barrier between the KUKA robotic arm and the host computer software, realize the accurate control of the robotic arm and the reading and feedback of position information, and ensure the stable, safe and efficient work of the equipment system.
Follow-up
Beijing Jiyuan Automation also provides fieldbus gateways, welcome to choose.
