ns=2;s=DEPRAG Smart/Devices/DEPRAG/AST/ActiveDevices/0/SystemOverview/ToolData/ToolDataItemsCount

Requests the number of items of tool data.

Returns:

    ToolDataItemsCount
    A variable of type OpcMethodReturnValueInt32. The Result property contains the command-specific return values.

Examples:

In addition to the parameters already explained, the following variables must be created / transferred for the implementation in TwinCAT 3:

Beckhoff parameter:

    bAstToolDataItemsCount
    A boolean variable that can be used to trigger the execution of the ToolDataItemsCount command.
    outputAstToolDataItemsCount
    An instance of the ST_Int32OutputData structure into which the return value of the ToolDataItemsCount method is written.
    hrAstToolDataItemsCount
    This can be used to monitor the execution of the command. Error codes have the type HRESULT.
    fbAst
    An instance of the FB_AST function block supplied with the DEPRAG Smart library.
    sDeviceId
    A string value specifying the device for which tool data is to be fetched.
    ConnectionHandle
    "ConnectionHandle" received when establishing a connection between DEPRAG Smart Server and your OPC UA client.

     bAstToolDataItemsCount    : BOOL;
     outputAstToolDataItemsCount   : ST_Int32OutputData;                                          
     hrAstToolDataItemsCount    : HRESULT;

     fbAst   : FB_AST;
END_VAR

hrAstToolDataItemsCount := fbAst.ToolDataItemsCount(
       bExecute    := bAstToolDataItemsCount,   
       ConnectionHandle := depragSmartConnection.ConnectionHandle,
       sDeviceId   := '0',
       OutputData   => outputAstToolDataItemsCount);
IF hrAstToolDataItemsCount <> S_FALSE THEN 
 bAstToolDataItemsCount := FALSE;
END_IF
