When you launch DOX Mini, the first step is selecting the exact Messung PLC model (e.g., Messung NX-2000 or NX-3000). The software automatically configures the memory map, I/O addressing, and cycle time based on the chosen CPU.
Messung’s flagship controllers, including the modern , the Nexgen series , and the compact NX-ERA Xpress , are all programmed using CODESYS . dox mini software messung plc
| Problem | Likely Cause | DOX Mini Solution | | :--- | :--- | :--- | | “Communication Timeout” | Wrong COM port or baud rate | Use “Auto-Detect” in Communication Settings | | “Overlap in I/O Addressing” | Double-mapped I/O card | Open Hardware Config → Re-number addresses | | PLC goes to STOP mode | Watchdog timeout due to infinite loop | The Diagnostic Buffer (accessible in DOX Mini) shows the last 50 events. Use debug mode to set breakpoints. | | Modified code not taking effect | Incomplete download | Use “Rebuild All” then “Download (Complete)” | | Analog input reads 32767 always | Sensor wiring loss or invalid scaling | Check the I/O map; use the “Monitor” view to see raw counts before scaling. | When you launch DOX Mini, the first step
The current flagship, the series, exemplifies this evolution. It is a "micro PLC with macro features" that comes in various models (XP300, XP315, XP325, XP340, XP350) catering to different needs, from basic I/O control to advanced motion and web server capabilities. These modern PLCs utilize programming software like MasterTool IEC XE , which is built on the powerful CODESYS platform and fully supports all five IEC 61131-3 programming languages. | Problem | Likely Cause | DOX Mini
Here is why "DOX Mini" represents a critical link in the chain:
: It was a DOS-based software package designed to run on IBM-compatible PCs (minimum XT/AT models). Core Functionality : It provided a platform for programming using Ladder Diagrams , which remains the most common language for PLC control. Debugging Utility
