It maintains information about itself, provides a mechanism for inclusive OPC item objects, and logically implements management of OPC items.

It provides an interface method for reading/writing and communicating with the data source, which can dynamically create or release group objects.

The OPC server includes three types of objects: a server object, a group object, and an item object.

O stands for OLE (object linking and embedding), P (process process), C (control control).
