About OLE for Process Control

OLE for Process Control (
OPC®
) is an open and inter-operable interface standard, based on the functional requirements of Microsoft’s OLE/COM technology that fosters inter-operability between automation/control applications and box systems/devices.
OPC offers advantages for connecting to non-Allen-Bradley devices, because OPC is
  • Highly efficient
  • Reliable (particularly over network)
  • Actively supported by Microsoft
    TIP:
    For applications running on
    PanelView Plus 7
    ,
    PanelView Plus 6
    ,
    PanelView Plus
    ,
    PanelView Plus Compact
    , or

     computers.
To set up the application as an OPC client
  1. Set up an OPC data server, specifying the OPC server name (ProgID), host computer name (if the server is remote) and a local name and, optionally, a description.
  2. In the tag database, define a tag with Device as its data source.
  3. In the
    Address
    box, specify the OPC item that will provide values for the tag.
For information on deploying OPC servers on a
