OPC Library

Headquarter OPC Library

The Headquarter OPC Library (Global_OPC_HQ_1) contains the default set of Data Type definitions and related object models supported by the current version of Desigo CC and is available at the following path: System Settings > Libraries > L1-Headquarter > Global > OPC. This library lets you interact with OPC objects without any changes to the configuration.

Information

Only Headquarter experts and Customer Support are authorized to modify the OPC library at L1-Headquarter level.
Depending on their allowed customization level, authorized experts can configure an OPC library at L2-Region, L3-Country, or L4-Project level.

OPC Library Customization

The Headquarter OPC Library (L1-Headquarter) can be customized to a lower level (L2-Region, L3-Country, or L4-Project). Customizing a standard library, means creating the library structure that will contain object models and any other relevant data (icons, text groups, symbols, and so on). See Defining a Custom OPC Library.

New OPC Library

To create a new OPC library with a specific object modelization, you have to manually create it and specify any required object models (see OPC Object Models and Create an OPC Object Model Configuration file (CSV)).

Information

NOTE 1:
Any new OPC library (L2-Region, L3-Country, or L4-Project level) exists together with the standard OPC library (L1-Headquarter level), and does not overwrite its data.

NOTE 2:
Only the OPC Data Types previously defined—contained in the default OPC Library or subsequently created with a CSV file import—can be used for the OPC configuration data to import.
