Can you add comments to inputs and outputs in ATV320 function block programming?

No, comments cannot be added directly to individual inputs or outputs in ATV320 function block programming.

The ATV320 supports comments at the function block level only, not at the level of specific inputs or outputs. This means you cannot attach descriptive notes directly to input or output connections.

Recommendation

To improve clarity in your program:

• Use the function block comment field to describe the logic and behavior.
• Clearly explain how inputs and outputs interact within that block.

Example:

“Relay R1 is activated when both DI1 and DI2 are ON.”

This approach helps document your logic even without input/output-level comments.
