OPC Support
Easy to use, comprehensive OPC support
The Cogent DataHub Can act as both an OPC server and client program at the same time. This means it can read from multiple OPC server (while acting as an OPC client) and make this data available to any number of OPC client programs (while acting as an OPC server).

OPC DA support
- Cogent DataHub will connect to OPC DA 3.0 servers (and 2.05a servers that support browsing).
- Cogent DataHub will also accept connections from OPC DA 3.0 or 2.05a clients.
- OPC Aggregation is performed as a natural behaviour within the DataHub. Connect to multiple OPC DA servers and you can store the data in a common data set within the DataHub, while maintaining an internal separation to effectively partition the incoming data.
OPC A&E support
The OPC A&E support within the Cogent DataHub allows it to act as an aggregator and tunneller for alarms and events. The DataHub doesn't generate the alarms and events itself, it reads them from installed OPC A&E servers. The DataHub acts as an A&E client program to bring data into the DataHub, where it can be used by any other DataHub client program. The DataHub can also act as an A&E server to offer the aggregated data to an A&E client program. The DataHub can tunnel the A&E data and make it available to A&E clients on remote network computers.
OPC A&E to DA conversion
The Cogent DataHub can also convert from OPC A&E to OPC DA, which allows you to use the A&E data in a non-A&E client program. For example, you could show A&E data in an HMI program using a simple DA conversion.. The OPC DA client program can even acknowledge the alarms through the DA interface even though the underlying systems is an A&E server.
OPC A&E history
OPC A&E servers do not usually store history, but the Cogent DataHub will store a small amount of history for recent events in addition to sharing the current status of those alarms.
