Today we learned something about PLC. PLC stands for Programmable Logic Controller. PLC is a type of industrial computer system used for automation of manufacturing processes. When we first saw PLCs we were very happy ,because we had a large selection of equipment. After we worked on some theory ,the proffesor let us work on plcs and gave us task. The task was to connect plcs with pneumatics cylinders. The only problem was ,when connecting the plc because with one error in the system ,the whole system does not work. But in the end we managed to complete task.
