Extract text from DeltaV configuration files (FHX)
To convert FHX configuration files to another format, you need DeltaV Explorer or other Settings software.
To convert other file formats to the "DCS Configuration Export" file type, you need software like DeltaV Explorer or a similar tool.
The .FHX file extension primarily belongs to DeltaV Configuration Export files. These files are generated by the Emerson DeltaV Distributed Control System (DCS), a platform heavily used in industrial automation and manufacturing. Engineers use .FHX files to backup, transfer, or export control logic and system configurations via the DeltaV Explorer software. A secondary use for .FHX files is the Heidelberg cross-dating format, which stores dendrochronology (tree-ring) data used by scientific measurement tools like CooRecorder.
The main disadvantage of the .FHX format is its strict reliance on expensive, proprietary software. You cannot use these files natively in standard office applications or web browsers. DeltaV exports contain complex, nested control logic that is nearly impossible to interpret without the original DCS environment. Similarly, the tree-ring data variant is highly niche and requires specific scientific tools to plot or read the data correctly.
To make this data accessible to non-engineers, users often need to convert .FHX to TXT, CSV, or XML. Because DeltaV .FHX files are typically encoded as plain UTF-16 (LE) text, extracting the raw configuration data is possible. However, translating the complex hierarchy into a clean spreadsheet usually requires custom parsing scripts, and native logic visualizations will be lost.
Because this is a closed, proprietary format, standard online converters usually fail to process it.
Convert.Guru analyzes your FHX file, detects the exact format, and lets you read the text inside.
Users also converted FH, FH11, CXO, DLV3 and EX1 files.
If you want to convert FHX file to , you can use DeltaV Explorer or similar software from the "Control System Configuration Export" category. In the File menu, look for Save As… or Export….
To convert files to FHX, try DeltaV Explorer or another comparable tool in the "Control System Configuration Export" 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 FHX converter.
