OPC UA Supported Standard Data Types

The following table lists the OPC UA supported data types.

The nodes in Desigo CC are created if the variable has at least one of the access levels specified in the table.

If the variable has Read access only, the node value is available for reading.
If the variable has Write access, a Write command is available for the node value.
If the variable has History Read access, a SORIS trend is created with the node history values. Note that trends are not created for array variables, even if they have History Read access.
