Start-up in Normal Mode with Safety Validated

What does 3040H mean?

This error occurs when the I/O module with diagnostic functions is started in normal mode, but its safety module function remains enabled. The module will not operate normally until the safety module function is successfully disabled, as indicated by 'Disable (0)' in Validation status area (Un\G5377).

• I/O module with diagnostic functions started in normal mode while the safety module function is still enabled.
• 'Enable (1)' is stored in Validation status area (Un\G5377), indicating the safety function is active despite being in normal mode.
