Automatic barman

I was working on a project of the automated bartender, whose construction has already been done. At the beginning I had to acquaint with construction and understand how it should work. I created the software in developmental environment CoDeSys in version 2.3 and later in version 3.5. Both of them allows the program creation, as well as visualization and online monitoring of PLC operation and debugging. PLC communicates via AS-interface. The aim of this project was to create fully functional application for barman. PLC program is structured as a state machine, which is ideal for this application. State machine is written in the developmental environment in language SFC and its individual steps in LD, ST, or FBD. I focused on simplicity and clarity of the program, in which I tried to incorporate as many features as possible. I managed to create a program that is able to tap one of the 4 or mix of any number of drinks. It can be also said that the operator doesn't want a full glass, but fewer doses than the maximum. The main acquisition for me was the fact that I was able to solve the problem independently, using the programmable controller on a real system, which gave me lots of new skills. The result of this work is fully functional automated barman including visualization that shows the status of sensors, the number of doses for individual drinks and allows to control the whole system and check error messages
