About Collecting Vendor Attributes from a Data Source

Data sources are often customized to include information specific to a site's installation in the form of vendor attributes. This customization adds data not covered by the OPC or OPCAE specifications and may or may not require storage in the Historian Archive. As a result, the Historian Administrator provides a means to specify which vendor attributes will be collected from any given data source. A maximum of 10 vendor attributes can be collected.
