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
Review the program logic to identify where the CNC_LoadProgramFile instruction or similar non-multi-execution CNC instructions are called.
- 2
Ensure that only one instance of the CNC_LoadProgramFile instruction (or equivalent) is executed at any given time.
- 3
Modify the program to enforce sequential execution for instructions that do not support multi-execution, preventing concurrent calls.
