An RSLogix symbol file is stored in the EAS format and is classified as a data file used by the RSLogix software. This application and the EAS format was developed by Rockwell Automation as a program that complies with IEC-1131 standards. This software and the EAS format are also integrated with functionalities for the development of programmable controller documentation materials. Text descriptions and address symbols of the associated documentation database are stored in these EAS files, which are affixed with the .eas extension. The RSLogix software locates associated EAS files and references the data stored in these files when required to find and display symbols and documentation data requested by the RSLogix user. This application can be installed in computers running on Microsoft Windows-based system to implement support for creating and viewing or editing the content of these EAS files. The content of an EAS file is encoded with ASCII specifications and implemented with plain text standards.

a word of warning

Be careful not to rename the extension on .eas files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .eas. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
