Hello everyone:
I recently developed a simple case to assist B&R PLCs in data acquisition and communication with PC databases. With simple data point configuration on the PLC side, stable small-scale data acquisition from the PLC can be achieved. The PC-side program provides examples in both Python and C++, allowing you to choose based on your needs. The test case provides an example with approximately 80 data points and a write frequency of once per second.
The example code is available at: GitHub - cwjwudi/br-mysql-connector.
If you have any questions, feel free to discuss them with me.
