Use /opcstopstat when both interfaces in failover pair are shut down

We would like to have some sort of digital state such as "Intf Shut" written to all OPC tags when both interfaces in a failover pair are shut down. Currently, the /opcstopstat and /stopstat parameters (which write a specified state to all tags wh...

Device status tags do not show OPC DA server Invalid client handle errors

When OPC DA interface receives an "Server returned Invalid Client Handle" error, device status tags do not show that error and therefore potential situations where data is not being received by the interface are missed I would be good that device ...

Parameter for restarting the interface if no connection to the OPC server can be established after a defined period of time

We use the Phoenix Contact Firewall with the OPC Inspector. When the OPC server restarts or breaks the connection for a few seconds, the firewall blocks all ports except port 135. After initial connection through this port, new firewall rules are ...

Add a configuration option to the OPC DA Interface so that the user can adjust the maximum advise tag exception delay for Event/Trigger tags

This affect to delay in Event\Trigger points. KCS: Delay in Event Points. When using Event Points, we purposefully do have a delay (if excMax is > 2 s then 2 s else 0.9*excMax) for advise tags (Trigger Point) before they're sent to the PI Serv...

Add a configuration option to UniInt so that the user can adjust the minimum wait time for checking for new events from the Update Manager

This affects the delay in Event\Trigger tags. KCS: Delay in Event Points. The largest and most variable delay seems to come from the time the event is written to the PI Server and the time the interface (UniInt) picks, which is between 0ms-1,000m...

Any Patches/Updates needed to be ready for Microsoft's DCOM hardening in 2023?

By March 2023 Microsoft will enforce a patch that upgrades DCOM security. Some applications that use DCOM (such as the PI OPC interface) will require some updates to continue to work. Are there any updates that I need to apply on any of the PI com...

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.
