V5.2.0.3 is here!

New in SQL4automation: DNS-Based PLC Authentication. Previously, SQL4automation stored the IP address of the PLC on the first request. All subsequent requests had to come from exactly that IP. Now, a DNS name can be stored instead.

The Benefits

More flexibility with IP changes: DHCP reassignments or network adjustments no longer cause interrupted connections.

Easier maintenance: Device replacements or moves to other subnets without reconfiguration in S4A.

Security remains intact: Authentication is still firmly bound to a defined target, now simply name-based rather than IP-based.

Further improvements

Alongside this new feature, we have implemented numerous smaller optimizations in this release that make SQL4automation even more stable and reliable in daily use. Particular attention was paid to connection stability in the area of Sentinel Cloud licensing. Targeted adjustments here ensure that your systems work consistently and reliably even under fluctuating network conditions. Many of these improvements are noticeable in the background: fewer interruptions, more robust processes, and an overall smoother user experience.

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.
