Representation for PLC programs programs are in view of more simple conversion represent at tree structure. Algorithm for conversion is based on manipulation with tree structure. Object of this diploma thesis is computer model design of chosen technological process. Next comes summary of Windows operating system features both positive and negative. There are some reasons for applying the Windows operating system in automation, DDE communication protocol is one of them.
Technological process chosen for modelling is a simple filling machine.
Object program is Windows executable, which animates all actions of process subsystems. It is necessary to run an external control system. It is necessary to run an external control system for proper model function. Model is applicable for automation control teaching. Petr Hor ek, CSc.
