Fixed an issue in the caching mechanism that could, in rare cases, incorrectly trigger a cache miss. As a result, clients could receive a "no data" error even though valid data was already available in the server cache.
This release serves as a baseline milestone representing the current state of the MAZAK MAZATROL SMOOTH OPC UA Server. Starting with version 3.13.0, all subsequent releases are published on dpaxt.com.
Previous releases introduced support for communication with MAZATROL SMOOTH C, G, and X series controllers. File transfer capabilities were implemented, including program upload and download between the OPC UA server and the CNC controller, together with essential file system management operations.
The server is built on the shared DPA platform and uses an asynchronous processing model with data caching and transaction scheduling. This architecture enables efficient operation with a large number of OPC UA clients while minimizing the load on the CNC controller. Error handling and reconnection logic have also been improved to provide reliable operation in unstable network environments.
At the platform level, several enhancements were made to improve portability and reliability. The build infrastructure was unified, and the overall stability of the server during long-term industrial operation was significantly increased.
