• 2 – Current Card
• 3 – Shutdown Card
• 4 – Pumpup Card
• 5 – Reference Card
• 6 – Start Card
• 7 – Fluid Fill Data Group (EIE specific support)
• 8 – Ideal Card
• 9 – Alarm Card
• 10 – Failure Card

AbortAllRequests

The AbortAllRequests method aborts all card poll requests. See Aborting Card Requests.

Syntax

AbortAllRequests()

AbortCurrentRequest

The AbortCurrentRequest method aborts all current card poll requests. See Aborting Card Requests.

Syntax

AbortCurrentRequest()

AboutBox

The AboutBox method displays an About dialog box for the control.

Syntax

AboutBox()

AddCalcMethodFilter

The AdCalcMethodFilter method adds a calculation method filter to limit downhole cards based on relevant calculation type(s) used in a single transaction.

Syntax

AddCalcMethodFilter(CalcType As String)

Parameters

CanGetFromRtu

The CanGetFromRtu method returns true if the user can retrieve data from RTU. The user can retrieve data if they have the necessary security credentials. For card data groups, the user must have necessary security credentials and the EIE must support the particular card type.

Syntax

Parameters

CanSendToRtu

The CanSendToRtu method returns true if the user can send data to RTU. Pumpoff configuration and fluid fill data can be sent if the user has the necessary security credentials and the data has been read from the RTU already. Reference cards can be sent if the EIE supports writing reference cards and the user has the necessary security credentials.

Syntax

CanSendToRtu(DataGroup As Integer) As Boolean

Parameters

ChooseFacility

The ChooseFilter method displays a Facility Chooser dialog box and returns the selected facilities in an array.

Syntax

ChooseSiteService() As String

ClearCalcMethodFilters

The ClearCalcMethodFilter method clears a calculation method filter. Results in the display of all available card types.

Syntax

ClearCalcMethodFilters()

Parameters

GetCardPairFromRtu

The GetCardPairFromRtu method issues a poll for the two specified DynaCard data groups.

Syntax

GetCardPairFromRtu(DataGroup1 As Integer, NumCards1 As Integer, DataGroup2 As Integer, NumCards2 As Integer) As Boolean

Parameters

GetDeviceType

Syntax

GetDeviceType() As String

GetDownholeCalcMethods

See IsCalcMethodFilter method.

Syntax

GetDownholeCalcMethods(ByRef arrFilterCriteria)

GetFacilityCount

Syntax

GetFacilityCount() As Integer

GetFromRtu

The GetFromRtu method issues a poll for the specified data group.

Syntax

GetFromRtu(DataGroup As Integer) As Boolean

Parameters

GetLastRequestError

Syntax

GetLastRequestError(ErrorText, ErrorTimeUtc, Clear As Boolean) As Boolean

Parameters

GetRequestQueueCount

Syntax

GetRequestQueueCount() As Long

GetRequestQueueCurrent

Syntax

GetRequestQueueCurrent(DataGroup, FirstCard, LastCard) As Boolean

Parameters

GetSelectedCardDataElement

The GetSelectedCardDataElement method returns the data value for a data element in the DDS transaction of the currently selected card. Deid is the name of the data element requested and if it is an ordinalized data element (like the load and position values are). Index is the ordinal of the data element to retrieve.

Syntax

GetSelectedCardDataElement(Deid As String, Index As Integer) As String

Parameters

GetSelectedCardDbKey

The GetSelectedCardDbKey method returns the DDS DbKey for the currently selected card.

Syntax

GetSelectedCardDbKey() As String

GetSelectedCardToken

The GetSelectedCardToken method returns the token for the currently selected card.

Syntax

GetSelectedCardToken() As String

GetSelectedCardXml

The GetSelectedCardXml method returns the XML for the DDS transaction of the currently selected card.

Syntax

GetSelectedCardXml() As String

IsCalcMethodFilter

Syntax

IsCalcMethodFilter(arrFilterCriteria As String) As Long

Parameters

IsCardTraceActive

The IsCardTraceActive method determines whether the card trace is active or not. See Executing a Card Trace.

Syntax

IsCardTraceActive() As Boolean

IsSelectedCardMostRecent

The IsSelectedCardMostRecent method enables a user to call the function to determine whether the selected card is the most recently retrieved card of its type. Boolean value returned.

Syntax

IsSelectedCardMostRecent() As Boolean

Navigate

The Navigate method chooses the next pump off control device for the UIS service if nNavObject is 0, or the next card for the selected device if nNavObject is 1. If bGoForward is True, this will navigate forwards to the next device or the next card, and if bGoForward is False this will navigate backwards to the previous device or previous card. Calling this function causes the CardChange event to fire if the selected device has a card of the set card type.
