3Configuring Siemens PLC

For PLC, Siemens S-1200PLC is used. Siemens PLC needs to be configured and programmed in Botu software.
After the program
is completed, the communication settings between the robot and PLC can be set. First, select the device and
network in the Porto software, then add a new device and select the controller model as Siemens 1212, as shown
in Figure 5. After adding the device, you need to set up
the PLC network. The computer and PLC must set corresponding IP addresses in the same network segment to
facilitate downloading and uploading PLC programs. After the settings are completed, click on the project tree
on the left to select the program block, and then enter
program writing. After the entire program is written, you can check whether the robot has received the signal from
the PLC through the input and output menu call in the ABB industrial robot teaching pendant, or you
can check online whether the PLC has received the signal from the
robot through the Botu software. When the line connection is good, the operator can set some signals to
complete the test work. If the test communication is normal, further PLC programming can be performed.

4 Conclusion

This article explains in detail the communication setting process between ABB industrial robots and Siemens
PLC, making full use of the characteristics of industrial fieldbus technology. During the communication process
, signal settings are based on DeviceNet fieldbus technology. The actual operation verifies the content described
in this article. feasibility. In communication settings, special attention should be paid to the process of setting parameters such as address signals. Based on
DeviceNet fieldbus technology, communication between ABB industrial robots and PLCs can be completed more
quickly and conveniently.

In modern industry, the communication technology between industrial robots and PLC has improved the level
of production line automation and can better utilize the flexible and expandable characteristics of industrial robots.
Therefore, it is foreseeable that the application of communication technology in the production line will continue to
increase, thus exerting a great influence on industrial production. greater effect.
