Be informed that OPC item classes can be easily imported, along with the OPC item
list, from a CSV file (see page 12). For more general information about MM8000 OPC
item classes and how to configure them, please refer to section 4 on page 29.
Checking OPC items
The configured OPC items can be validated in order to make sure that the OPC
server is actually supporting all the linked items. This verification can be performed
using the “Validate” button in the Advanced setting section of the OPC driver link
node (see Fig 5 above). Proceed as follows:
1. Select the OPC driver link node node
2. Click Validate in the Advanced setting
3. In the windows that appears, click “Connect” and then “Start”
4. The items are checked done after the other and the corresponding tag
names and descriptions appear in the list. On the right hand side, the
“Test Result” column shows whether the test passed or failed (Fig 17).
5. The faulty items can be removed right away from the MM8000 link list:
the procedure prompts you for an immediate purge.

representation that you need for them. The OPC subsystem needs to be populated
with the appropriate list of points. Proceed as follows:
1. Select the OPC unit node.
2. In the toolbar menu, select the OPC object icons to add new nodes.
