WinCC flexible/OPC-Server
Non-proprietary communication
OPC (OLE for Process Control) designates a standardized, non-proprietary software interface. OPC is based on COM (Component Object Model),
DCOM (Distributed COM) Windows technologies or on XML (Extended Markup Language).
Using the SIMATIC WinCC flexible/OPC-Server option, you can use Windows-based systems like the SIMATIC
Panel PC with WinCC flexible or SIMATIC Multi Panels, for example, for
tasks that are close to machines and the process. At the same time, they
can communicate with any OPC-capable application across an Ethernet.

Benefits:
Incorporation of automation components from
different vendors into an automation concept
Saving of development costs through
communication between automation systems based on a
homogeneous, uniform protocol
The sensitive field level is not loaded by the
control level as far as the communications requirements are
concerned.
From PC platforms, you can make available current process data in this way via OPC DA (Data Access) or, in
the case of multifunctional platforms via OPC-XML, to several OPC clients.
This means that locally acquired data is available on a plant-wide basis to
provide important information at a central location or to make possible (central) archiving of process data.
Among other things, linking to MES, ERP or Office applications is possible.You can choose the relevant tags on
the OPC client across the entire network using the OPC Browser from the OPC servers Tag Management.
PCs with WinCC flexible Runtime can also be OPC DA clients and acquire data from other OPC servers.
The OPC client is delivered as standard with WinCC flexible Runtime.
