Rework Collection Mode

In automatic mode, a direct connection to the PLC:

• Rework counts are recorded at regular intervals.
• A rework counter in the PLC can be linked to a specific rework counter.
• Provides the highest level of accuracy.

In manual real-time mode, operators record rework counts during operation:

• At regular intervals to simulate the machine’s rework as operations progress.
• Additional effort is required from operators.
• Accuracy is lower compared to automatic data collection.
• Often used when the PLC cannot provide rework counts to the application.

Operators record rework counts at the end of period such as:

• The end of the production run to record reworked quantities for the order.
• Or at the end of their shift to record reworked quantities for the order before they hand over to the next shift.

The exact date and time of the rework counts is not logged.

• Only the total quantity is logged for the current period (hour/job/shift).
• The total quantity is usually an estimate.
