This report provides an updated and extended description Version 2. 4 of the structure and the operation of the controller software developed for digital Czochralski Growth Control System CGCS for compound semiconductors. This manual outdates all previous versions. The Controller Software Reference Manual discusses the design considerations applied to digital LEC crystal growth control, gives a short overview of the growth controller computer hardware and operating system environment, describes the functions of the CGCS from an operators point of view, and delineates the internal operations of the controller software by discussing the controller software and algorithms. Various appendices provide tables of controller software tasks, routines, and variables, file format information, and lists of system messages and error codes. Keywords Liquid encapsulated Czochralski, Crystals.
