REXLANG read / write parameter example

The source files located in this folder illustrate the use of a REXLANG function block in order to get and set input/output/parameter of arbitrary block in REXYGEN.

On change of CNI1, CNR1 or CNS1 values REXLANG will set values of corresponding blocks (CNI, CNR, CNS). REXLANG will also get values from CNI, CNR, CNS and write it to REXLANG outputs.

Timing of the project

The algorithm runs each 100 milliseconds (0.1 s). See the EXEC function block,
tick x ntick0 = 0.05 x 2 = 0.1 s


  • 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.
  • Change CNI1, CNR1 or CNS1. Observe changes.
