OPC Filter

Do you want to restrict access to data on OPC servers or harmonize the namespaces of OPC servers from different manufacturers?

The OPC Filter lets you restrict access to data on an OPC server, hide individual items, rename items and control access rights. This offers you the following advantages:

• Greater security for your whole system by preventing accidental or deliberate inappropriate access
• Saves time and money on project engineering by reducing data in your client application
• Simplifies data management by harmonizing access to the namespaces of different OPC servers
• No programming required

• Restricts access to OPC items using an OPC filter file
• OPC filter file can be created in a GUI or Excel
• Hides sensitive items on OPC servers to prevent access to them
• Allows access rights to be restricted for defined items
• Simplifies the handling of very complex namespaces through filtering
• Harmonizes the namespaces of different OPC servers through an alias function
• Allows an OPC server to be exchanged without affecting the OPC client application
• Supports OPC DA 1.0a, 2.0, 3.0, XML-DA 1.0
• Can run as an application or as a Windows service
• Comes with its own Web server diagnostic interface

• Windows NT 4, 2000, XP, 2003, Vista

• CD-ROM
• Printed "Getting Started" manual
• Online help in German and English

• OPC-EC-BCL

Basic license for OPC Storage, Bridge, Optimizer, Tunnel, Concentrator, Filter, Collector and OPCtoDataBase

• OPC-EC-SRV-XX/L

Extension licence to OPC-EC-BCL for the access to max. XX OPC servers at the same time with XX = 10, 20, 50, or 100;

• License Manager

• Engineering Days

The OPC Filter makes it possible to adjust which items are offered by an OPC server.

The OPC filter can be used to:

• hide items
• change the data type of items
• restrict access rights to items
• change the item ID of items

The filter works regardless of whether you use DCOM, XML DA or the OPC tunnel to communicate with the OPC server.

Restricting items

The OPC Filter allows you to control access rights and restrict the items offered by an OPC server to the ones you require. This increases the security of your system by preventing accidental or deliberate inappropriate access to these items.

Harmonizing the OPC namespace

With the OPC Filter, you can harmonize the structure of the items in your system regardless of the OPC servers you are using. This allows servers to be exchanged without affecting the OPC clients, for example.
