    Clarity on the current state of EDS 1.0:

    1. Local access is via unencrypted over HTTP
    2. Remote administration is achieved via SSH which is encrypted
    3. EDS egress to PI Web API and OCS is via TLS encrypted HTTPS endpoints
    4. EDS Adapter to Device is dependent on the protocol. Modbus in unencrypted, OPC UA requires TLS.

    Regarding the limit of 1000 - this has been improved in more recent versions of PI Builder. While the search dialog itself will only display the first 1000 in PI Builder, as long as you don't begin selecting individual results from that dialog, all Event Frames which match the criteria will be imported.

    Beginning in the 2018 (2.10) version, PI Builder will give you an option to append tags to the existing list in the spreadsheet after performing a search.

    PI Builder can import from a list tags. Select the point attributes you want via the "Headers" option, fill in tag names in the the spreadsheet's name column, and click the "Retrieve" button in the tool ribbon (it was called Refresh in earlier version of PI Builder but performs the same function).

    While PI Builder does not support all the search options of the advanced tab of the PI Tag Configurator search dialog, it can perform the searches you mentioned. Any point attribute can be searched on but this does required typing the point attribute into the search text box. As you begin typing in the UI search box, it will help you with the point attribute names. "location1:3" or "creationdate:>2019-1-1" are examples of valid searches. Multiple clauses are AND'ed together. As of 2018, you can search on snapshot values as well: "Value:>100", timestamps: "timestamp<*-1h" and quality (IsGood, Questionable, Substituted, and Annotated)

    It does. If the attribute is an array, then all rows that match the lookup will be returned in the value.

    If there were multiple UOMs abbreviations, applications may accept them, but they would all be displayed using the same standard abbreviation. Roger, your use case of using in different locales would not apply, unless we also added locale information to each abbreviation. The complexity there is likely unwarranted.

    The OR clause is planned for AF 2018 SP2 and will be available in PI Builder, although it requires typing of the OR clause directly in the search box - for example: "Template:T1 OR Template:T2".

    In AF 2017 and later, you can also include multiple templates IF you can identify them by name with wild card using the TemplateName filter. For example "TemplateName:T*". Note that this clause must be typed into the to search box - there is not an independent control on the search form.

    Can you clarify? In PI System Explorer, you can specifically choose which elements you wish to export by multi-selecting them in either the "Child Elements" tab - or - doing a search and multi-selecting them in the results grid. Right click on one of the selected elements, and export.

    You cannot, however, choose to NOT export the child elements of any particular element you have selected in PSE. So, for example, it would not be possible to export a parent element and only some of it's children.

    Within the AF SDK, this is possible by using the PIExportMode.NoReferences flag and passing a specific list of elements (the NoReferences would also cause no Analyses, Notifications or associated Templates to be exported)

    For the spans implementation, let’s consider implications on PI, OCS and EDS. E.g. how does the data source represent spans and/or how does the OMF application recognize these spans? Who / what uses the span data? How does the thing using the span data represent a span and associated data? Do we have scenarios with non-time based spans for OCS and EDS?

    This has worked for some time in PSE. Is there a specific use that I am not understanding?

    You can get the top level root via the %\Element% substitution parameter. Getting other levels is not currently possible without additional string builder's which can copy down the attribute as suggested

    Can you explain why you need access to this dialog for the built-in data references? That is, why is this dialog more useful than the built-in dialogs?

    Just making sure you are aware you can add these columns via the settings drop-down in the grid view of af elements, eventframes, and most other "top-level" objects . Once you add the columns, the setting will be remembered. They are not currently shown by default, however.

    The step attribute indicates a basic behavior of the data, and controls more than the trend - but behavior in interpolation.  If the change is only for the behavior of a trend - perhaps it would be better to override the behavior in a trend setting.  Can you explain a bit more the use case?

    I can see that the "Clear to Empty Cell Boundary" option is not always being honored in the new import case, only during "Retrieve".  We will try to address that in a future release.

    Under the Settings menu item, for the Retrieve tab, there is a setting to control the addition of the two row/column border. If you change the setting to "Clear to Empty Cell boundary, and then also leave the header row blank past the last PI Builder utilized column, this should achieve what you want.

    Is the request for this specific to a client application, such as PI Vision?

    Is this specific to PI System Explorer, PI Builder, or PI Vision? PI Builder does have this option. PI System Explorer does not.

    In response to Zev Arnold, "Nope!  I was wrong.  I fixed my issue, b..."
    There are many things that make an on-demand rollup taxing on the system - more so than might be apparent.   General expectations for time-series based attributes is the ability to notify on change, summarize, trend, interpolate, calculate previous values, etc.  Meeting those requirements and dealing with a potentially dynamically changing and potentially quite large set of input attributes - including nested rollups - does not make sense when we have the PI Data archive available to store those results.  Is there a particular reason, other than cost of a tag, that you are avoiding tag creation?

    Can you be more specific? AF has been making improvements to the security setting dialog each release of AF Client. AF 2.9 will also have the ability to edit identities and mappings of PI Data Archive and AF Server within PI Builder, allowing users to more easily share identities and mappings between servers.

    A future enhancement request we are aware of is to allow users to see the effective permission of a particular user or identity within PSE or eventual web-based configuration tool.

    It will not be possible to dis-allow read permission on templates.

    However, by default, Event Frames get their read permission from the ReadData permission of the template. Would it be adequate to remove the templates for which the user does not have ReadData permision from the search list in Datalink (and PSE, Coresight, etc?).
