A295.10
Illegal Area Access Error
Omron · SYSMAC CJ2 CPU Unit
What does A295.10 mean?
This flag indicates an Illegal Area Access Error. This fault occurs when the program attempts to read from or write to a memory area that it does not have permission to access, is outside of defined boundaries, or is reserved by the system. This is a critical memory protection violation.
Common Causes
- Attempting to access a protected or undefined memory region (e.g., system reserved area, non-existent address).
- Array indexing out of bounds, trying to read/write beyond allocated array size.
- Corruption of pointer variables leading to invalid memory addresses.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Review program code extensively for memory access instructions to ensure they target valid and accessible data areas.
- 2
Carefully check array bounds and pointer operations to prevent out-of-range access.
- 3
Implement robust data validation for any calculated memory addresses before attempting access.
