Tag Import

You can use Plant SCADA's Import Variables Tags tool to automatically create variable tags that correspond to S7 1200/1500 PLC items.

To create variable tags based on S7 tag properties:

1. Open Plant SCADA Studio.

2. In the Topology activity select I/O Devices, then Import Tags.

3. In the Destination panel, select the required I/O Device. The drop-down menu includes a list of all the I/O devices currently configured in your Plant SCADA project. The device you select needs to be configured to use the S7TCP protocol, otherwise an error message will appear when you attempt to configure the device connection.

4. In the Source panel, set the Database type to "S7TCP". You can ignore the value of the External database field.

5. Click Browse… to display the S7TCP Browse dialog box. To select the tags for import:

   1. Click Browse… to display all the tags corresponding to S7 PLC. Plant SCADA will connect to the S7 PLC to read the tag database.

   2. Select the items you want to import. The selected items will be added to the list at the bottom of the page.

   3. If you want to prefix the I/O device name to the tag names, select the check box I/O Device name as a prefix to tag name.

   4. When you have made your selections, click OK.

6. Click Import. Plant SCADA will create tags for all selected items.

   Note:
   • The number of items which can be browsed for a PLC, and the number of tags you can import, is limited to 100,000.
   • If the name of the tag is greater than 78 characters, then it will be truncated to 78 characters. A warning message will be logged in the tag import log file.

7. On Tag Import Results dialog box, click Yes to display the log file.
