Configuring the OPC item classes for MM8000 handling
If you have not imported the OPC item class using the import file (only possible
with the option 1 above), you have now to define which OPC item class is associ-
ated to each item. The item class describes the type of item or, more precisely, the
conversion rule to apply in order to exchange data (in one or both directions) be-
tween the OPC item and the MM8000 data point. To configure the item class:
1. Expand the Composer branch containing the OPC items.
2. Select the first item and then the Node tab.
 On the right, the OPC class form appears (Fig 16).
3. In the ‘Tag properties’ section, select the item type (or the type of data
conversion to apply).
