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 35).

3. In the ‘Tag properties’ section, select the item type (or the type of data

conversion to apply, see Tab.1 below).

4. Continue with the next item until the end.
