Extract text from FactoryTalk View files (MER)
To convert MER files to another format, you need FactoryTalk View Studio or other Executable software.
To convert other file formats to the "Compiled HMI Terminal File" file type, you need software like FactoryTalk View Studio or a similar tool.
The .MER file is primarily a compiled Machine Edition Runtime application created by Rockwell Automation FactoryTalk View Studio. It stores compiled Human-Machine Interface (HMI) screens, PLC communication tags, and system logic required to operate PanelView Plus industrial terminals. Internally, modern versions utilize the Microsoft Compound File Binary Format to package these components.
.MER files are highly proprietary and present significant challenges for average users. They are designed to be executed on specific industrial hardware, not viewed on a standard computer. Standard online converters fail to process them because the file is a compiled binary lacking a generic visual representation like a standard document or image. Furthermore, opening these files normally requires an expensive, specialized software license.
To view or edit the HMI logic, users must attempt to restore the .MER file back to a development project format, such as MED or an APA archive. This is done using the Application Manager tool within FactoryTalk View Studio. However, this conversion process is frequently blocked. Developers can intentionally disable the restoration feature during the initial compilation to protect their intellectual property. Files compiled in versions older than 5.0 generally cannot be restored at all.
Because this is a closed, proprietary format, standard conversion workflows do not apply.
Convert.Guru analyzes your MER file, detects the exact format, and lets you read the text inside.
Users also converted APA, MERMAID, ACD, ZIP, TBS, EDS, RSV, MED and AER files.
If you want to convert MER file to APA, MED, AER, JS, TS, PY, JAVA, CPP, C, CS, PHP or RB, you can use FactoryTalk View Studio or similar software from the "HMI Runtime Application" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to MER, try FactoryTalk View Studio or another comparable tool in the "HMI Runtime Application" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our MER converter.
