    Can you tell me what you would use this information for?

    In response to Stephen Kwan, "Can you tell me what you would use this ..." Hi Stephen!   It is useful to bring information about which instrument tag is used in the opc source.   Therefore, if you see a faulty signal in  PI the operators can easily find the signal  inside the source.   As now you have to check that up in PI SMT and it takes some time.   Regards   Magnus

    I would also like this functionality to be available. I want to extract the intrumenttag attribute from a Ping PiPoint, and set it´s value into a Write PiPoint so I can send it to our OPC server. It can be any other attribute, not just the instrument tag one.

    Does the information in the InstrumentTag attribute change with time?

    In response to Stephen Kwan, "Does the information in the InstrumentTa..." Hi Stephen!   Normally it should not change! But since we have not got an optimal naming convention we are constantly working to improve it.   Therefore it would be great to have this function.   Regards Magnus Holmbom   Från: Stephen Kwan Skickat: den 29 juli 2019 17:12 Till: Holmbom Magnus (GV-PP) Ämne: Re:  - Function to retrieve Instrument tag   PI Square   Function to retrieve Instrument tag new comment by Stephen Kwan View all comments on this idea

    Hi, I understand what you're trying to do. However, please keep in mind that AF/Analytics was designed to be a streaming calculation engine. We designed it assuming that users would use it as a way to perform calculations with a schedule, e.g. every time there is a new trigger event for the calculation or based on a clock schedule. What you're describing seems to be a manageability need that may not happen very often, i.e. not in a streaming fashion. Therefore, with the information that you have provided, this request would not be high priority for us.

    Hi Stephen, We would very much appreciate if this request gets prioritized. I have been in touch with OSIsoft account manager regarding this feature. We want to use Instrument tag information to cross reference other databases to pull metadata and safe operating limits etc. into AF. This is essential for optimal use of event frames. All other methods require lot of manual work or unnecessary extensive customization. Our scada tags change from time to time due to field works so maintaining them in AF manually is quite difficult. Given that some tag functions already exist, this seems like an easy Win!!. Regards, Manbir

    I would like to see this as well. We have interfaces to other systems and sometimes we have system administrators from those systems that would like to check the underlying mapping(instrumenttag) for a PI Tag via the AF element using PI Vision - They may not have PI System Explorer and even if they did would need some training to show them how to perform the tag search. I would rather just make this information available as an attribute in the AF structure. There are already some related Point Attribute functions like TagExDesc and TagSource that provide similar information but recommending a TagInstrumentTag function to retrieve this information.
