Connect OPC A&E servers and clients

OPC Alarms and Events (Classic), or OPC A&E, protocol from the OPC Foundation provides a way to track, report, and acknowledge alarms and events in a Windows system.

The Cogent DataHub can act as both an OPC A&E server and client program at the same time. This means it can read from multiple OPC A&E servers (while acting as a client) and make this data available to any number of OPC A&E client programs (while acting as a server).

Note: the DataHub cannot be configured to act as a source for generating alarms and events, but if it is configured as an OPC A&E client, it can pass along A&E values. This is useful for tunnelling A&E data, converting A&E data to OPC DA or OPC UA data, and allowing OPC DA or UA clients to interact with and display data from OPC A&E servers. Automatic A&E ↔ OPC DA and A&E ↔ OPC UA protocol conversions are built-in.
