High-speed test stand for car tires (retrofit)
A new controller (Siemens Simatic S7) was set up in conjunction with a measurement data acquisition system on an existing customer high-speed test stand (up to 400 km/h) for passenger car tires. Various test orders are read from an ERP system and stored in a separate SQL database. From there, the test orders can be loaded into the controller and processed.

During the ongoing test, the current process values (speed, temperature, tire pressure, circumferential speed, and more) are written to a database in conjunction with the order number. When the test is aborted or successfully completed, the calculated results are written back to the existing ERP system and the order status is set.
Workflow:
- Cyclically reading and capturing open test orders from ERP
- Selecting a test order and mounting (setting up) the appropriate test specimen
- Starting the test order
- Writing the test result to ERP and setting the test status
Technical data:
- Controller: Siemens Simatic S7-315 PN/DP
- SQL4Connector V3.x
- Connection to 2 databases (ERP production database, measurement data acquisition)
