I was recently tasked with saving backup files for our FactoryTalk View SE HMIs onto a USB drive. I have a few questions regarding this process: 1. What is the distinction between MER and APA files? 2. Is it advisable to backup both file types? 3. Are these files automatically saved in a designated folder, or do I need to manually initiate an archiving process? Any guidance on this matter would be greatly appreciated. Thank you.
1. What sets apart MER and APA files? MER stands for Machine Edition Runtime, a compiled version of an application running on a PV terminal that cannot be edited. On the other hand, APA refers to Application Archive, a zipped version of the development application that is also not editable. Another important file type is MED or Machine Edition Development, which is the file you work on in FactoryTalk View Studio and can be edited. During development, the MED file is converted into a MER file for loading onto the PV, with the option to revert the MER file back to MED. The ability to prevent unauthorized access is crucial for small businesses or individuals. When sharing a project for review, creating an APA backup can be useful, but sending a MER file can achieve the same outcome. For developers, backing up the MED (APA) is recommended, while users may opt for backing up the MER file for easy PV reloading without additional software. 2. Should I backup both MER and APA files? Developers should prioritize backing up the MED (APA) file, while backing up the MER file may suffice for users. Although previously, backing up the restricted MER file had limited benefits, the ability to restore MER to a development copy (MED) makes it a valuable backup item and reduces the importance of APA backups. 3. Are MER, APA, and MED files automatically saved or require manual archiving? MER and APA files can be saved in any desired location on the PC, while MED files must be stored in a specific folder with no option for relocation (making MED backups unnecessary). There are no automated backup processes in place, so manual archiving is necessary.
Thank you for sharing valuable information. Can you guide me on how to save MER and APA files? Could you provide steps on how to create these specific file formats?
The APA is created within the Application Manager system, which may seem chaotic but actually functions as a robust program. In the world of manufacturing engineering, the procedure involves compiling the runtime within FactoryTalk View Studio. To access the Application drop-down menu, simply click on Create Runtime Application. It's possible that the process is similar for System Engineering (SE) as well.
After performing a backup, I navigated to "Tools > Application Manager > Create a Backup" and generated an "apb" file. What is this file format used for?
When it comes to SE, there is no direct equivalent in terms of Runtime functionality. Following the steps mentioned by dmroeder will allow you to obtain the APA file. This program was previously known as "Application Manager," although newer versions may refer to it as the "Machine Edition Application Manager" or something similar. You have the option to run it independently or within FT View Studio by accessing it through the Tools menu. Additionally, FT View Studio software can be used to generate Runtime and save it in a location of your choice. If you already have the APA file, using the MER may not be necessary. For further information, RA has a helpful video available on YouTube: https://www.youtube.com/watch?v=7r_LOD4FJbYOG.
In response to your questions, MER files refer to the compiled versions of your FactoryTalk View Studio project and they're the ones that run on your terminals. Conversely, APA files serve as the application backup, preserving the project in editable or design mode. It's generally a good idea to back up both file types. The MER ensures that you can quickly recover a project on the terminal, while the APA allows you to revise or restore the project in FactoryTalk View Studio. To answer your last question, these files are not automatically saved or backed up. You need to manually create these backups. The good news is, it's quite straightforward. Just go to your project in FactoryTalk View Studio, click 'Application', and select 'Backup'. Hope this helps!
Hey there! To start, MER files contain the compiled items for the project and are specific to the PanelView terminal, while APA files are application backups that contain the entire HMI project including graphics, tags, etc. It's generally beneficial to backup both, as they provide different levels of recovery if something goes wrong. As for your third question, files are not automatically saved. In FactoryTalk View Studio, you should manually initiate the backup by choosing Application > Backup... Hope this helps guide you in the right direction!

Answer: - MER files are runtime application files used for deploying an application, while APA files are project archive files that store project configuration information in FactoryTalk View SE HMIs.
Answer: - It is advisable to backup both file types for comprehensive data protection and to ensure you have a complete set of files to restore in case of system failure or data loss.
Answer: - The files may not be automatically saved in a designated folder. It is recommended to manually initiate an archiving process to ensure regular backups are created and stored in a secure location for easy retrieval when needed.
