Processor Incorrectly Converted Address

What does F001 mean?

This error signifies that the processor encountered an issue when attempting to convert a logical address into a physical memory address. This prevents the processor from locating or accessing the intended data or instruction, leading to execution failures.

• Incorrect or invalid memory address referenced in the program.
• Corruption in the processor's address mapping tables.
• Software bug in the address conversion routine.

1. 1

   Measure the input supply voltage to the PLC rack and processor module, verifying it is stable and within the manufacturer's specified operating limits.

2. 2

   Inspect all PLC modules within the rack for proper seating and secure latching on the backplane, ensuring stable communication pathways.

3. 3

   Verify the integrity of the PLC program by comparing the running version against the last known good file, specifically reviewing logic related to indirect addressing, pointers, or array manipulations for potential errors.

4. 4

   Retrieve and analyze the processor's fault log and diagnostic buffers for any preceding error codes or events that could provide context to the F001 fault.
