Back to Items IndexItem - Batch Save
Please refer to Adding a New Item for specific information on how to add an ITEM and how to change its properties.
Description
The Batch_Save ITEM is used in conjunction with other Batch ITEMs. The Batch_Save ITEM will only save data in Batch related ITEMS.
This means that in a TASK that is set up for Batch Saving, extra items can be included for say calculations, which will not be included by the Batch_Save ITEM.
The Batch_Save ITEM is designed to append data to a MicroSoft Access 7 Data Base.
Properties

| Dbase Table Name | Enter a unique name for the Table in the Data Base, this will most likely represent the process or area. |
| Encrypt Dbase | If the Dbase is encrypted then it will be more secure but access speed will be slightly slower. |
| Dbase Password | Enter a password for the Dbase if required. |
| Save Frequency | Every Scan - Saves data each time the TASK is
updated. Only at End - Saves data only at the end of the Batch. |
| Batch Run | Select the ITEM that is setup monitor the Batch Run. |
| Calc Batch Length In | Each time the Batch is saved to disk the ITEM calculates how long the Batch has been running. The calculation can be made in; Days, Hours, Minutes, or Seconds. |
Note: If you are saving data only at the end of the Batch, then it would be best to order the ITEMS as follows:
The above order will mean that when the TASK is updated and the Batch has just stopped, then the Batch_Save ITEM will save the value of the other ITEMS. Only the value of the other ITEMS will still be from the previous update whilst the Batch was running. Hence the data from the last update when the Batch was running will be saved. This is because when a TASK updates, it updates its ITEMS in sequential order starting with the first ITEM.
