TTControl offers various alternatives to program its ECUs and operator terminals. The products support C programming as well as standardized modelling environments such as CoDeSys or MATLAB/Simulink. Whereas MATLAB/Simulink is the most suitable solution for the development of complex control algorithms, CoDeSys is one of the most common IEC 61131-3 programming systems for industrial and mobile controllers. Version 2.3 of this integrated development environment is used for the HY-Vision, HY-TTC 50 and HY-TTC 200 product families, whereas version 3 is being utilized for the HY-eVision² operator terminals.
