from the field to MM8000 via the OPC server.
Format type and MM8000 property are required. Supported formats are: Enu-

item class must be selected in a drop-down list.

Add a transaction data. This is an OPC data for acquiring a transaction informa-

transaction property is required and must be selected in a drop-down list.
4.3 Configuration examples
4.3.1 Item class for on/off conditions
The item classes define the conversion rules to be applied when moving informa-
tion from OPC server to MM8000 and vice versa.
For example, an on/off condition, stored in OPC items as numeric 0/1 value and
controlled by active and de-active commands, can be converted into the
MM8000 Active property as illustrated in the next two images.
A state life-cycle data (Fig 41) defines that OPC values 0 and 1 are associated to
the Quiet and Active states, respectively. Also, Active/Deactive commands are
available (note that the appropriate command, either Active or De-active, will be
presented by the MM8000 software based on the current property state).
Fig 41 Item class definition (states) for on/off conditions
For the same item class, a command life-cycle data (Fig 42) defines the OPC val-
ues corresponding to the De-active and Active commands.
