This error occurs when the address specified in a command or instruction is syntactically correct but refers to a non-existent or invalid memory location. The processor cannot find the target, preventing data access or instruction execution.

• Reference to a memory address outside the processor's valid range.
• Attempting to access a protected or reserved memory area.
• Outdated or incorrect address used after program modification.

1. 1

   Cross-reference the fault tag or instruction within the PLC program to locate the specific address causing the F003 error.

2. 2

   Verify the existence and proper configuration of the referenced I/O module or device within the PLC's I/O tree against the physical hardware.

3. 3

   Inspect the PLC program's tag database to ensure the referenced tag or memory location is correctly defined and within the processor's accessible memory scope.

4. 4

   Review the program logic surrounding the identified instruction for indirect addressing, array indexing, or pointer errors that might dynamically generate an invalid target address.
