Incomplete Address

What does F002 mean?

This fault indicates that the address provided in a command or instruction is incomplete, lacking necessary components for the processor to uniquely identify the target memory location. This prevents the processor from performing the requested operation.

• Missing address segment in a message instruction.
• Partial or truncated address received due to communication issues.
• Programming error leaving an address undefined.

1. 1

   Review the PLC's major/minor fault log or diagnostic buffer to identify the specific instruction or memory location that triggered the F002 'Incomplete Address' fault.

2. 2

   Verify the identified program instruction's addressing syntax, tag names, and data types against the PLC's tag database and memory mapping.

3. 3

   Inspect the I/O configuration in the PLC project to ensure all referenced I/O modules and their addresses are correctly defined and present in the I/O tree.

4. 4

   Check for any incomplete or inconsistent tag definitions (e.g., array dimensions, structure members) that are part of the faulty address.
