Building object structures
OPC servers
Start the configuration work from the server objects. Before an OPC client can be taken
into use, an OPC server has to be configured for the process communication.
The object tree is built in the communication tab of CET. There are several possible
ways to build an object tree. One of them is to build the object tree by adding objects in
logical order starting from the OPC server object. You can either use basic or pre-defined
objects. Using basic objects means that you have to configure the objects manually. If
objects are pre-defined, they are preliminary configured and all the necessary child
objects are automatically added.
Add the objects in the following order:
1. OPC server object
2. Channel/Subnetwork object depending on protocol
3. Device object
4. Logical device object(s)
5. Logical node object(s)
6. Data objects.
If you want to connect events or scales to data objects or
device connection status event classes to device objects at this
point, make sure that you have already created and configured
the event and scale objects.
For more detailed information on adding objects to the object tree, refer to the appropriate
protocol manual (see 1.8, Related documents).
Substation structure for HMI
Configuring the substation is the main task in configuring HMI functionality. If connectiv-
ity packages or IED SCL description files with substation structure information are used,
most of the substation structure can be built automatically when the IEDs are added to
the communication structure. If no substation structure information is available the
structure must be built manually.
Before you can create a substation structure, you have to create
a communication structure with OPC Server and communica-
tion channel objects, IEDs, Logical Devices, Logical Nodes
and Data objects.
