ST_OK if the command was successfully sent to the DataHub. Since the command is sent asynchronously, the actual success or failure of the command must be determined through the onSuccess or onError message handlers.
ST_NO_TASK if a connection to the DataHub does not exist.
ST_ERROR if the connection socket is unable to send the message.
This method stops changes to the specified DataHub point from invoking the onPointChange method. If the DataHub point does not exist, then the DataHub will respond with an error, and onError will be called with the following arguments:
status: ST_NO_POINT |
msg: "Point does not exist" |
