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。

debug an arbitrary number of tags belonging to a PI OPC interface instance

It is currently possible to debug one tag, or all tags. Logging timestamp and data for all tags is expensive and make logs harder to read, so one one would like to select an arbitrary number of tags.

PI Interface for OPC DA retry writing data when it receives a CONNECT_E_ADVISELIMIT error.

I would like the ability for the PI Interface for OPC DA to retry writing data when it receives a CONNECT_E_ADVISELIMIT error. Certain OPC servers return a CONNECT_E_ADVISELIMIT error when write requests are received in quick succession, and havin...

Clamp Value at Limit

Ability to clamp or ignore values outside a threshold. Example would be to clamp the low value to 'zero' attribute and/or a high value at 'span' - many xmtrs read erratically when at limit (e.g., an empty flow transmitter often reads negative)

Support redundancy with OPC event tags

Currently, with OPC event tags, if the connection between the interface and PI Data Archive is broken and signups lost, the event tags will stop polling the OPC server for data. I would like to see a level of redundancy added whereby if the OPC-PI...
