What does 56200000 hex mean?

This error occurs in the CNC Function Module if multiple instances of a CNC instruction (e.g., CNC_LoadProgramFile) are executed simultaneously. This indicates a violation of the instruction's single-execution constraint, causing system resource exhaustion or conflict.

Common Causes

  • Multiple instances of a CNC instruction that does not support multi-execution (e.g., CNC_LoadProgramFile) are executed concurrently.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Review the program logic to identify where the CNC_LoadProgramFile instruction or similar non-multi-execution CNC instructions are called.

  2. 2

    Ensure that only one instance of the CNC_LoadProgramFile instruction (or equivalent) is executed at any given time.

  3. 3

    Modify the program to enforce sequential execution for instructions that do not support multi-execution, preventing concurrent calls.
