ns=2;s=DEPRAG Smart/Devices/DEPRAG/AST/RemoveDevice

Terminates the connection to the device and removes it from the ActiveDevices list.

Parameters:

    Id
    An Int32 value specifying the device to be removed from the list of devices registered with the DEPRAG Smart OPC UA Server.

Returns:

    RemoveDevice
    A variable of type OpcMethodReturnValueInt32. The Result property contains the command-specific return values.
      Result
      An Int32 value that returns the Id of the device that has been removed from the list of devices registered with the DEPRAG Smart OPC UA Server.

Examples:

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

Beckhoff parameter:

    bAstRemoveDevice
    A boolean variable that can be used to trigger the execution of the RemoveDevice command.
    outputAstRemoveDevice
    An instance of the ST_Int32OutputData structure into which the return value of the RemoveDevice method is written.
    hrAstRemoveDevice
    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.
    nDeviceId
    A DINT value specifying the device to be removed from the list of devices registered with the DEPRAG Smart OPC UA Server.
    ConnectionHandle
    "ConnectionHandle" received when establishing a connection between DEPRAG Smart Server and your OPC UA client.
