Example of operation: Control Loop Data
A new dataset with the control loop data that you selected while configuration will be created. The resulting dataset will have tags that you selected for each loop as columns.
Initial dataset
Loop 1 with 15 seconds sampling period
| Timestamp | Tag_PV | Loop_P |
| 7/5/2022 6:15:43.300 PM | 0 | 86 |
| 7/5/2022 6:15:58.300 PM | 10 | 50 |
| 7/5/2022 6:16:13.300 PM | 25 | 30 |
Loop 2 with 10 seconds sampling period
| Timestamp | Tag_PV | Loop_P |
| 7/5/2022 6:15:45.500 PM | 5 | 8 |
| 7/5/2022 6:15:55.500 PM | 12 | 20 |
| 7/5/2022 6:16:05.500 PM | 11 | 18 |
Example 1: Resampling is Auto
If you select this option, control loop data is resampled using the sampling rate available on the selected control loops. All data are resampled using the control loop with the smallest sampling period. Here in this example, the lowest sampling period is 10 seconds.
Configuration
Loops selected- Loop 1 and Loop 2
Tags selected - Tag_PV, Loop_P
Time Window- In this example, the import operation was executed on 7/5/2022 at 7 PM and the time window selected was Last 1 hour.
Resampling - Auto (Use smallest sampling period on selected loops)
Resulting dataset
| Timestamp | Loop1_Tag_PV | Loop1_Loop_P | Loop2_Tag_PV | Loop2_Loop_P |
| 7/5/2022 6:15:43 PM | 0 | 86 | ||
| 7/5/2022 6:15:53 PM | 0 | 86 | 5 | 8 |
| 7/5/2022 6:16:03 PM | 10 | 50 | 12 | 20 |
| 7/5/2022 6:16:13 PM | 25 | 30 | 11 | 18 |
| 7/5/2022 6:16:23 PM | 25 | 30 | 11 | 18 |
| 7/5/2022 6:16:33 PM | 25 | 30 | 11 | 18 |
| Will list all data till the current timestamp. | ||||
NOTE: In this example, since the Loop 2 did not have any data on 7/5/2022 at 6:15:43 PM, the dataset contains empty Loop2_Tag_PV and Loop2_Loop_P columns for that period. However, if there was data available before 6:15:43 PM, the dataset would have contained that data, like what you see for the timestamp 7/5/2022 6:16:23 PM.
Example 2: Resampling is None
If you select this option, no resampling will be applied to the imported dataset and all the raw data for each control loop will be included in the dataset.
Configuration
Loops selected- Loop 1 and Loop 2
Tags selected - Tag_PV, Loop_P
Time Window- In this example, the import operation was executed on 7/5/2022 at 7 PM and the time window selected was Last 1 hour.
Resampling - None
Resulting dataset
| Timestamp | Loop1_Tag_PV | Loop1_Loop_P | Loop2_Tag_PV | Loop2_Loop_P |
| 7/5/2022 6:15:43.300 PM | 0 | 86 | ||
| 7/5/2022 6:15:45.500 PM | 0 | 86 | 5 | 8 |
| 7/5/2022 6:15:55.500 PM | 0 | 86 | 12 | 20 |
| 7/5/2022 6:15:58.300 PM | 10 | 50 | 12 | 20 |
| 7/5/2022 6:16:05.500 PM | 10 | 50 | 11 | 18 |
| 7/5/2022 6:16:13.300 PM | 25 | 30 | 11 | 18 |
The dataset returns all the available raw data based on the timestamp.
Example 3: Resampling is Custom
If you select this option, the Sampling Period (in sec) text field is enabled. You can type the required sampling period. All imported data will be resampled at the rate specified.
Configuration
Loops selected- Loop 1 and Loop 2
Tags selected - Tag_PV, Loop_P
Time Window- In this example, the import operation was executed on 7/5/2022 at 7 PM and the time window selected was Last 1 hour.
Resampling - Custom
Sampling Period (in sec)- 8 seconds
Resulting dataset
| Timestamp | Loop1_Tag_PV | Loop1_Loop_P | Loop2_Tag_PV | Loop2_Loop_P |
| 7/5/2022 6:15:43 PM | 0 | 86 | ||
| 7/5/2022 6:15:51 PM | 0 | 86 | 5 | 8 |
| 7/5/2022 6:15:59 PM | 10 | 50 | 12 | 20 |
| 7/5/2022 6:16:07 PM | 10 | 50 | 11 | 18 |
| 7/5/2022 6:16:15 PM | 25 | 30 | 11 | 18 |
| 7/5/2022 6:16:23 PM | 25 | 30 | 11 | 18 |
| 7/5/2022 6:16:31 PM | 25 | 30 | 11 | 18 |
| Will list all data till the current timestamp. | ||||
The dataset returns all the available data for the selected sampling period.
