To use Elipse E3's OPC Server, there is no need to any extra configurations, just execute a Domain so that any OPC Client can communicate with Elipse E3. To connect to an Elipse E3's OPC Server from any Client, select the Server identified as Elipse.OPCSvr.1.

An OPC Server allows any Client to easily import all Tag definitions to a Domain (the Browse function). Of course, the available Tags are just objects that are part of a Server, that is, Screen items (Elipse E3 Viewer) are not accessible using an OPC Server.

Because it is based on the same linking technology used by internal Links among objects, Elipse E3's OPC Server allows Clients to use Tags that are mathematical expressions, and with transparent connection or disconnection during execution.
