    OPC interface retries sending InstrumentTag/ItemID to OPC Server

    The idea is to have PI Interface for OPC DA/HDA to be able to send again Instrument Tag/Item ID after a configurable time when OPC Server is not able to resolve it (AddItem failed). This would be a workaround for an OPC server issue and would help...

    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 ...

    Automatic restart of the OPC interface whenever OPC server is restarted

    whenever the OPC server undergoes any restarts or configuration changes, the OPC interface will delete all old connections, groups, etc. and it will establish a new connection to the OPC server, loading all ItemID's etc (as if it is an automatic r...

    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...
