Problem Statement: Does the Web.21 version of the Excel Add-in pull data using Web.21? If an IP.21 server is behind a firewall with the primary access via Web.21, will the Excel Add-in use the Web.21 server as a data source, so it uses the existing firewall connection? | Solution: The add-in uses the same data retrieval mechanism as the Web.21 ActiveX plot pages - Process Data and RDS. If the plot pages work using various firewall configurations, then so should the add-in.
