Fault 06 — Timer Not Resetting

Briefing

A cyclic process runs once but never repeats. The first cycle completes correctly, but subsequent start commands have no effect. The timer output stays permanently true after the first completion.

Objectives

• Use the Variables tab to watch T_CYCLE.ET across multiple cycle starts
• Identify why the timer's elapsed time never resets to 0
• Find and fix the missing reset logic for the timer enable
• Verify the cycle repeats correctly after your fix

I/O Table

Your program will be tested against:

All test cases run automatically when you submit. Assertions are hidden until you pass.

1. #1First cycle completes after start

   START_CMD → RUNNING_LAMP ON → after 500ms CYCLE_COMPLETE pulses

2. #2Cycle can be restarted after completion

   After the first cycle, a second START_CMD restarts the cycle
