Control of manufacturing line

The main task of this project was to design a program for control system of dry concrete product handling line. This manufacturing line is controlled by a programmable logical controller Simatic S7 300 produced by Siemens company. A graphical touch panel TP 177A and a control desk with buttons are used as human machine interface. The developed program contains functions for control conveyors, manipulator and cleaning station. Management of formulations stored in PLC by operator is also included in program. The theoretical part deals with dimensioning of drives for two mechanical systems of this manufacturing line. Choice of power output of the electric motors depends on required torque. A fundamental principles and rules of five basic programming languages for PLC in accordance with standard IEC 61131-3 are specified here. The practical part describes project creation in Step 7 software and functions and capabilities of projected system by means of user manual
