Export and import the Gateway item data

The Export and Import commands on the shortcut menu enable you to export and import the Gateway Communication Driver item data to and from a CSV file, after the configuration of the Device Items has been completed. These commands will allow you to perform an off-line, large-scale edit on the item data configured for a controller, and import what has been edited back into the controller configuration.

The Export and Import features on the shortcut menu of the Device Items dialog box enable you to export and import the Gateway Communication Driver device item data to and from a CSV file, after the configuration of the Device Items has been completed. These features provide you with the following capabilities:

• Archive lists of device items.

• Bring an archived list of device items into the Device Items dialog box when you need to utilize or reconfigure any of the device items on the archived list.

• Perform an off-line, large-scale edit on the item data configured for a PLC.

  • Import what has been edited back into the PLC configuration.

When you want to archive a list of device items, use the Export feature in the Device Items configuration view.

1. Right-click anywhere in the Device Items configuration view, and select the Export command from the shortcut menu.

2. Select the folder into which the list is to be saved.

3. Name the list to be exported.

   The entire list is saved as a .csv file.

Import device items

The Import feature in the Device Items configuration view is used to import an archived list of device items into the configuration view.

5. Right-click anywhere in the Device Items configuration view, and select the Import command from the shortcut menu.

6. Select the archived list (.csv file) to be imported, and click Open.

Resolving Item Names from Clients

Gateway Communication Driver resolves item names from its clients at runtime in the following order:

System items (those prefixed with $SYS$) > Device items (those defined in the Device Items configuration view) > All other items (validated directly from the PLC device)
