    - tan()
      Calculates the tangent.
    - tanh()
      Calculates the hyperbolic tangent.
    - tcpClose()
      Closes a TCP/IP socket connection.
    - tcpOpen()
      Opens the connection to a TCP/IP server socket.
    - tcpRead()
      Reads the data of a defined socket, which was opened with tcpOpen().
    - tcpShutdownOutput()
      Closes the write direction of a TCP socket.
    - tcpWrite()
      Writes data to the defined socket.
    - textEditor()
      Opens the text editor as a main window (not modally).
    - throw()
      Signals an erroneous condition by using an error class variable.
    - throwError()
      Passes a WinCC OA error to the internal error handler.
    - timeFromGMT()
      Returns the difference between local time and GMT.
    - timedFunc()
      Starts timed CTRL functions.
    - timedFuncEvents()
      The function timedFuncEvents() returns up to a given max_count all planned start_times (occurrences) when WinCC OA timedFunc would trigger a (start-)event. This function also handles the time periods (broadcast periods) (see Timed function extension) within the range defined by ’r;valid from’ and ’r;valid until’.
    - Timed function extension
      The timed function was extended and now provides several new functions:
    - The Extension timedFuncConflicts()
      The timed function extension "timedFuncConflicts()" is designed to discover call conflicts between two or more timed functions. It compares the given parameters to analyze all conflicts and returns the result times.
    - titleBar()
      Shows or hides the title bar in the specified module or in a child panel.
    - tmpnam()
      Creates temporary file names.
    - tr()
      The function translates the given combination (text, comment) into the requested language or the UI language if the lang argument is not given.
    - trackZoomMode()
      Complies with the function "Rubber band zoom". After calling this function a cursor "cross" is displayed, which allows to create a window by left-clicking. The panel is scaled in accordance with the specified window size.
    - triggerAction()
      The function can be used to trigger an action from a GEDI or Script Editor extension script.
    - triggerEvent()
      The function triggers a specific event.
    - triggerEventWait()
      The function triggers a specific event and waits for the execution of the event.
    - triggerGlobalEvent()
      The function triggers a UI global event.
    - tryUpdate()
      The function tryUpdate() tries to update the current license.
