OPC Server Directories
The OPC Server Directories show the OPC servers and items that the OPC Data Manager can access. The
left OPC Server Directory includes information for event servers. Icons next to the server names indicate
whether the server is an OPC data server
or an OPC event server .
Data Manager Groups
The Data Manager Groups section shows the groups that are currently defined. A group can have either a
uni-directional
or bi-directional default setting. Although this default setting is initially applied to
any point added to the group, you can change the setting for a specific point.
In a uni-directional point, information is transmitted in one direction only—from the Master OPC item
to the Slave OPC item. In a bi-directional point, information can be transmitted in both directions—
between the Master and Slave OPC items.
A&E Subscriptions
The A&E Subscriptions section is reserved for future use.
Details
The Details section can show information for all the points in a selected group.
