PROCON-WEB Embedded Systems 6.11.2

Warning

The port for accessing PROCON-WEB Embedded Systems has changed. The new port is now 17443.
The system now communicates securely, i.e. via HTTPS instead of HTTP.

The system can therefore be accessed at https://localhost:17443.

Access via the old port is no longer possible.

Fixes & improvements

  • 126062: Fixed an issue that prevented messages from switching languages at runtime.

Known issues

  • Firmware bug in Siemens 1500 series CPUs running firmware 4.x: Frequent connection and disconnection with the PLC visible in the event log. A fix via a firmware update from v4.0.4 onwards improves the situation, but does not resolve the problem completely. A solution is expected to be released with firmware 4.2 in December 2026. Further information in the Siemens Release Notes. TIA drivers are therefore not currently approved for firmware v4.x.

  • The TIA V2 driver does not currently support importing fields from structures. Instead, the driver creates an element for each index.

  • The setup for Windows systems does not create a port share, which is why streaming does not work. Port 17443 must be manually enabled in the Windows Defender Firewall in the incoming rules under Windows.
