Hi,

How to prevent POSINO of END from showing after I ran INTABORT in the early steps of my sequence?

Thanks.

 Hello SeeYoon,

What I understood from your post is:

• WhenINTABORT(Interrupt Abort) is executed, the sequence is not properly closed or reset, leading to an invalidPOSINOstatus at theENDstep.
• ThePOSINOvalue atENDis retained if the sequence doesn't go through a proper termination process.

Solution:

1. Ensure Proper Reset After INTABORT

   • After executing INTABORT, trigger a reset command(RESET) to clear any pending state.
   • This ensures that POSINO is reset and does not show at the END step.

2. Use an Additional Step for Cleanup

   • Add a cleanup step after INTABORT to clear the POSINO status explicitly.
   • Configure the cleanup step to automatically reset the sequence or transition to the idle state.

3. Check for Transition Conditions

   • Verify that all transition conditions in the sequence logic are correctly defined to handle anINTABORTcase.
   • Make sure that the transition fromINTABORTto the next step is configured to avoid thePOSINOstate.

4. Use Manual Confirmation (Optional)

   • If needed, introduce a manual confirmation step afterINTABORTto prevent unintended automatic transition toEND.

Example Fix:

• AfterINTABORT, insert a step with the following logic:
  • IfINTABORT = TRUE, executeRESET
  • AfterRESET, transition to the idle state or to the starting step

This should prevent thePOSINOfrom showing at theENDstep after an interrupted sequence.
