Model of the lift including AS-Interface network

This bachelor´s thesis occupies with a suggestion of the model of a lift which is driven by a serial industrial bus AS-Interface. In the introduction there is presented theoretical knowledge useful for the reader to the problems especially of the origin and fundamental parametrs of bus AS-Interface, description three levels referential model ISO/OSI which are included in AS-Interface. Further there is the description of transmission of analogical values and standard profiles which are used. In the other part I am trying to solve the model of the lift from the construction standpoint and function of component parts which are included in the lift model. The fourth part devotes to the communications protocol for the control of storeys and the cab box which are shown the data transmission between unit master and unit slave and the opposite. In the last part it is shown programming environment and routines and functions and connection unit slave to unit master. Enclosed are electrotechnical schemes of the model of the lift, the block of programme structure for PLC and technical docummentation of components
