| Status |
Description |
| 0 |
The state of the CNS view is currently not
defined because the OPC server is not running. If
the server has not been stopped properly (e.g.
using the KILL command) the last set status
remains until the OPC server is started
again. |
| 1 |
The distributed system is connected and the
CNS view or all OPC elements of the view are
correctly in the server's address space. The
values of all elements in the address space are
the same as the actual value of the respective
data point element. |
| 2 |
The distributed system is connected and a
delta synchronization is running. Connected OPC
clients are able to receive values from the OPC
server. |
| 3 |
The distributed system is connected and the
entire CNS view is refreshed in the OPC server's
address space (Full Sync). In this case, connected
OPC clients receive the last usable values from
the OPC server, which are marked with OPC quality
"Uncertain, Last Useable Vale". If one CNS view of
a system is in Full Sync state, all other CNS
views will be in this state also. |
| 4 |
The distributed system is connected, but the
configured CNS view does not exist or cannot be
found in the given system. |
| 5 |
The distributed system is not connected and
the server does not have any information about the
configured CNS views in the address space. As soon
as the distributed system is connected, the OPC
server does a full synchronization for all
views. |
| 6 |
The distributed system is not connected, the
OPC server has IP identification and CNS views in
its address space. The server marks all values of
the system of the CNS view with OPC quality status
"Uncertain, Last Usable Value". If the connection
to the distributed system is established, the OPC
server starts a full or a delta synchronization
depending on config entry maxUpdateMsgCouint and the
amount of changed data.
If the OPC server is started with useLocalIdentification,
the address space will be created with the
information loaded from the files
proj_path/data/DpMsgTypeContainer.bin and
proj_path/data/DpMsgIdentification.bin, so
TypeContainer and DpIdentification must not be
transmitted over the network.
