We are looking to migrate from Honeywell PHD to Pi, but we have a significant amount of calculated tags that will need to be replicated in PI AF. As an interim measure, is it possible to link an AF attribute to PHD tag data, either by an OPC connection or OLEDB or other such methods? Need to link to the PHD data, not import to PI,as there are often historic data recalculations in PHD that would need to be reflected for the client tools accessing PI AF. Anyone know if this is possible to do? Alternative suggestions?
