Adding Tags

Adding a Tag

To add a tag that is to be monitored by the system, proceed as follows:

1. In the Plant Connectivity Management Console, click on the Subscription Items tab.

2. Choose the Browse pushbutton.

   The Browse dialog box appears.

3. In this dialog box you can choose the Browse pushbutton to display and select the tags of the source.

   The system shows the Address Root. You can open the tree and display the individual tags.

4. Select a tag and choose the Add Selected Items pushbutton. Repeat this step to select all of the tags that you want.

5. Choose the OK pushbutton to adopt the selected tags.

6. Instead of selecting the tags individually, you can specify a filter criterion in the Filter field. PCo then displays only the tags that meet the filter criterion. See Filter Functions.

Adding a Tag Manually

Some source systems support adding subscription items manually. Adding tags manually allows you to enter the tag name directly without browsing. Adding tags manually is necessary if a data type is not supported, for example, for OPC UA applications. In this case the tags are not offered for selection when you are browsing. They are only displayed but cannot be adopted into the list and need to be added manually. (See also: Unsupported Data Types for OPC UA Applications.)

1. In the Plant Connectivity Management Console, click on the Subscription Items tab.

2. Click on the Add New Subscription Item Manually icon.

   The Add Subscription Item dialog box appears.

3. Enter the necessary data such as the name of the tag and a value for the deadband, if required.
