Fault 07 — Counter Overflow

Briefing

A parts-counting batch system runs the first batch correctly but locks up after that — subsequent BATCH_START commands have no effect. Use the Variables tab to watch the counter state across batches.

Objectives

• Use the Variables tab to watch C_PARTS.CV and C_PARTS.Q
• Count a full batch of 10 parts and observe the counter state
• Identify the missing counter reset logic
• Add a reset rung and verify subsequent batches work correctly

I/O Table

Your program will be tested against:

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

1. #1BATCH_DONE fires after 10 parts

   Count 10 parts — BATCH_DONE should go true

2. #2Second batch can be started after first completes

   After first batch, BATCH_START restarts the counter
