UniInt Interface to support Kerberos when connecting to network drive for failover file

My ops team tells me that our UniInt-based interfaces (e.g. PItoPI, PerfMon, OPC DA) authenticate to network drives (when reading/writing failover files) using NTLM. I'm told Kerberos is much more secure than NTLM and they would like to see that b...

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。

PI Interface for OPC DA and VT_ARRAY|VT_BSTR datatype

PI Interface for OPC DA has a plugin called "Time Array" to manage numerical arrays but string arrays are not supported. It would be a good improvement to develop this feature for string arrays.

Modifying the functionality of Trend Advise feature for PI OPC interface

As a PI OPC Interface user I would like to get step-like trends whenever that the Trend Advise parameter is enabled (even with having large exception and compression deviations that filter some of the events) so that I don't need to enable the ste...

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)

Automatically recreate advise groups when they are discarded by RSLinx OPC Server

The Rockwell RSLinx OPC Server may discard advise groups when there are too many bad quality tags or incorrect ItemIDs added to the group. The PI Interface for OPC DA should automatically recreate advise groups after it has determined that the gro...
