PI interface for OPC DAの配列型タグ対応

PI interface for OPC DAを配列タグ対応にしてほしい。東芝製DCSのデジタルデータの場合、状態を配列型で存在している(例：種別「PB8」、ITEM「LS1」の場合8ビット。種別「PB4」、ITEM「SS1」の場合4ビット)。この値を取得する際、1ビットずつ取得した後にAF演算で１つの値に計算している。対象全タグに対してこの処理を行うことは大変なので、interfaceのところで一度に全ビット取得し、1つの値として取り扱いたい。

Enhancement for Advise tags to poll OPC server when Excmax expires

Currently, when an advise tag does not get a value in an ExcMax period, the interface will send the same value to PI over again without going to the OPC server (assuming that the OPC interface has not disconnected from the OPC server during that ...
