Relationship between CCDB and OPC

What infomation is stored in the CCDB?

When you uses the SRVR Vi's are you talking to the Tag Engine or the CCDB?

Do 3rd party OPC servers have entries in the CCDB or has national instruments Created their own system to create automation drivers?

How do I access my VI IA Servers form other OPC Systesm?

Hope someone can help

Thanks

Hi,

CCDB stores info' from the VI-based servers and the (now obsolete) IAK Servers. Open it with MSAccess and you'll see what it contains.

The Server VIs write to CCDB which in turn is used by DSC for Tag creation, manipulation, etc.

OPC Servers do not have any entries in the CCDB file. CCDB file is proprietary to NI.

You can access your VI-based Server from a 3-rd party OPC Client via the DSC OPC Server. All currently loaded Tags of DSC are served up as OPC Items of the DSC OPC Server.

Hope this helps.

Regards,

Khalid 🙂
