Understanding ACH Issues
Typical ACH Opening Challenges
RSLogix 5 is Not Installed
If you attempt to load your ACH file, you experience a message such as "Can't Open ACH Files". Usually, this is because you do not have RSLogix 5 for %%os%% installed. The typical path of opening your ACH with a double-click won't work because %%os%% cannot make the program connection.
Tip: When you have another program installed that you know will open your ACH, you can select it from the other programs listed (see "Show Apps").
Wrong Version of RSLogix 5 is Installed
In some cases, you might have a newer (or older) version of a RSLogix 5 Project File file that is unsupported by your installed application version. Installing the latest version of RSLogix 5 from Rockwell Automation Inc. is recommended. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.
Tip: Right-clicking on your ACH, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.
Primarily, problems experienced when opening ACH files are due to having the incorrect version of RSLogix 5 installed on your computer.
Other ACH File Opening Causes
In the majority of cases, installing the right version of RSLogix 5 will resolve your issue. If you are still having problems opening ACH files, there may be other issues that are preventing you from opening these files. Additional factors include:
- Windows Registry ACH file paths that are incorrect
- The ACH file description within the Windows Registry was removed
- Invalid installation of a ACH-associated program (eg. RSLogix 5)
- The ACH itself is corrupted
- Malware-tainted ACH file can't be opened
- ACH-related hardware has device drivers that obsolete
- Windows has inadequate resources to open your RSLogix 5 Project File file
