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 25 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.
5. The faulty items can be removed right away from the MM8000 link list:
the procedure prompts you for an immediate purge.
Adding data points
Once the OPC items are configured and verified, you can focus on the MM8000
representation that you need for them. The S7 subsystem needs to be populated
with the appropriate list of points. Proceed as follows:
1. Select the S7 unit node.
2. In the toolbar menu, select the OPC object icons to add new nodes.
Build up the S7 structures using the available objects (Fig 36 and Fig 37)
