CAUTION! The 011 extension is and AI backup file!!
The extension for this particular file is .011. This is a backup extension for the old AI and APS software, which RSLogix can open just fine. Rather than rename the file extension to .RSS, it should have been renamed to .ACH. The .0XX extensions, where XX is a number are the automatic backups of previous versions made each time the file is saved. The most current version of the program will be the file with the .ACH extension. This is critical, because the .011 is not the current file.
The reason that the comments are not displayed when opening the file is because in the AI/APS software these were stored in seperate files.
I advise dnellington to repost the ZIP file set and zip up not only the .ACH file, but also the .ADR, .DSC. .RPI .ATT .NAM .XRF .SYM .CNT .RPD .XRI files if they exist. Then when opened the comments, symbols, cross reference, etc will be available and we can make a printout of the current version of the software with comments.
Dnellington, next time the PLC program is opened, do a "save as" and change the file type to .RSS - this will convert everything to the RSLogix-500 file format and eliminate the need for all the extra files. Then remove all the other files that don't end in .RSS to a backup directory so thay you don't have a problem of differentiating which file is the most current.
