For example, if you define **Manufacture Start From**: `0 `and **Manufacture Start To**: `1`, this means that when the value from the input tag, with the definition on the connection as *manufactureStart*, will go from 0 to 1, it is an indication that manufacture was started and production cycle should start to be calculated. Manufacture End works the same way. **Manufacture End From**: `2 `and **Manufacture End To**: `4 `means whenever the input tag with connection definition as *manufactureEnd *goes from 2 to 4, it is an indication that manufacture just ended. - After creating this KPI, you need to add definitions called *manufactureStart* and *manufactureEnd* to the connecting wire, which are event triggers, triggering whenever there is start of manufacturing event and then one more trigger for which represents the end of manufacturing cycle. # Production Cycle and Cycle Time Radio (CTR) Parameter | **Parameters** | **Details** | | ---------------------- | -------------------------------------------------------------------------------------------------------------------- | | Manufacture Start From | The value from which the Manufacture Start event is triggered.
| | Manufacture Start To | The value to which the Manufacture Start event is triggered. | | Manufacture End From | The value from which the Manufacture End event is triggered. | | Manufacture End To | The value to which the Manufacture End event is triggered. | | Ideal Cycle Time | The desired or standard production cycle time, in seconds. | | Timer Interval | Timer in milliseconds. If no event, use this timer to keep displaying the output continually. Enter zero to disable. | ![](https://api.archbee.com/api/optimize/SSUUxKZUk9bFTEPNn_6Zo/YcwEc4PMbE5fuwC8sBdt4_image.png "Production Cycle and Cycle Time Radio (CTR) Parameter") :::hint{type="info"} **Note: **When creating an analytics flow with *Production Cycle and Cycle Time Radio (CTR) *KPI, refer the [Use the Production Time and Cycle Time Ratio KPI](docId\:wCGJf3k_7ChhAL8KkmsDN) guide for more details. :::
