There is only one file type that uses the .MER extension:
RSView Development Runtime File
Runtime file created from an RSView development (.MED) file; contains program data that has been compiled and saved in an executable format; used for HMI (Human Machine Interface) applications.
NOTE: MER files cannot be converted back to MED files, so make sure not to delete the original MED file when creating a runtime file.
