What is RTM file?

File with .RTM extension contains LabVIEW VI virtual instrument menu data. RTM files use a format developed by National Instruments specifically for LabVIEW. The format is proprietary and each version of LabVIEW uses modified version of it.

A menu can comprise of:

  • default application commands,
  • Custom user-created elements,
  • VI functions,
  • VI operations.

Elements of given menu can be further divided to create submenus. Menu editor allows users to add, remove, or sort menu elements, as well as create submenus and custom control groups and views. Menu separators are also configurable. LabVIEW interface supports copy-and-paste menu editing. Each VI can have its own custom menu. Custom menus can be created using the default menu as a template for further customization or from scratch.

RTM files can be used by more than one virtual instrument using a link feature. It is also possible to manually select RTM file directory for selected VI by editing RunTimeMenuPath variable. The function allows users to use different language versions that can be switched in programmatic way. RTM files can be included with executable files for virtual instruments. LabVIEW development environment was released in 1986 for Macintosh computers as a data management and device control and automation software. LabVIEW is available for various platforms, including Microsoft Windows, Unix, and Linux. The software uses G programming language, a graphical language for controlling well-defined functional units called virtual instruments. Block diagram determines execution of programs.
