Logging to text file using the REXLANG function block

This folder contains the source files demonstrating the use of the REXLANG user-programmable function block of REXYGEN.

The user algorithm collects date, time and simulated temperature and stores the information into a text file when triggered. The algorithm itself is located in the logging_rexlang.c file.

Feel free to modify the algorithm to fit your needs, you can use arbitrary format of the log file.

The log file (rexlog.txt) is located in data folder (by default /rex/data on Linux machines).

Read the complete description of the REXLANG function block for more details.

Timing of the project

The algorithm runs each 500 milliseconds (0.5 s). See the EXEC function block,
tick x ntick0 = 0.05 x 10 = 0.5


  • REXYGEN Runtime Core must be installed and running on the target device.

Running the example

  • The *exec.mdl file is the project main file.
  • Open it with REXYGEN Studio, compile and download it to the target device.
  • Switch to Watch mode and observe the algorithm.
  • Observe the resulting text file.
