LMA File – What is .lma file and how to open it?

LMA File Format

An LMA file is a Logo! UDF file created by Siemens. UDF stands for user-defined function. LMA files are text files that contain code written in the Logo! programming language. They can be used to create custom functions that can be used in Logo! programs.

LMA files are similar to LGO files, which are also Logo! programs. However, LMA files are specifically designed for creating user-defined functions, while LGO files can be used to create any type of Logo! program.

To create an LMA file, you can use the Logo! Editor software. The Logo! Editor is a free software program that can be downloaded from the Siemens website. Once you have installed the Logo! Editor, you can create a new LMA file by clicking on the “File” menu and selecting “New.”

Opening LMA Files Using Siemens LOGO! Soft Comfort Software:

Logo! UDF files (.LMA) are proprietary files created by the Siemens LOGO! programming software. To open and edit these files, you will need to have the latest version of LOGO! Soft Comfort installed on your computer. Once installed, launch LOGO! Soft Comfort and click on the “File” menu. Select “Open” and navigate to the location of the LMA file you wish to open. Click on the file and then click “Open” again to load it into the software.

Alternative Methods for Opening LMA Files:

If you do not have access to Siemens LOGO! Soft Comfort, there are a few alternative methods you can use to open and view LMA files. One option is to use a text editor such as Notepad or Sublime Text. LMA files are essentially text files containing structured data. By opening them in a text editor, you can view the contents of the file, but you will not be able to edit or modify it. Another option is to use a third-party program such as UDFTerminator. This freeware tool can open and edit LMA files, allowing you to view and modify the contents. However, it is important to note that UDFTerminator does not support all the features and functionality of LOGO! Soft Comfort.

LMA File Format

The LMA file format is a proprietary file format used by the Siemens LOGO! PLC programming software. LMA files contain the source code for LOGO! programs, which can be used to control industrial automation systems. The LMA file format is based on the XML language, making it human-readable and editable with a text editor. LMA files can also be imported and exported in other file formats, such as LSC and LAD.

LMA files are divided into several sections, including the header, the program section, and the data section. The header section contains information about the file, such as the file version and the name of the LOGO! PLC that the program is intended for. The program section contains the source code for the LOGO! program, which is written in a high-level language called LOGO!. The data section contains the data that is used by the LOGO! program, such as variables, constants, and timers.
