If your controller has the ASCII Program Export option, you can save system parameters directly as readable text ( .TX or .VA ) files. Step 3: Create the PDF
FANUC robot system variables are the named memory locations and parameters inside a FANUC robot controller that store runtime state, configuration, and control values. They let programs, I/O logic, and system utilities read or change controller behavior without rewriting RAPID-like programs (for FANUC this is TP/TP+ or KAREL programs). Documentation is commonly distributed as PDF reference manuals that list each variable, its type, access rules, valid ranges, default values, and notes about when/where it’s supported.

| Access Type | Meaning | Description | |-------------|---------|-------------| | | Read only | Values are set automatically by the system and cannot be modified by users | | RW (Read/Write) | Read and write | Users can view and modify these values to customize system behavior | | FP (Field Protection) | Field protection | Applies access restrictions to individual fields within a structure | | NO (No Access) | No access | Cannot be accessed under normal operating conditions |
