Abstract

The thesis deals with the communication methods between the PLC S7-1500 and the database system and it focuses primarily on the possibilities of direct communication, i.e. without the need to use additional software. The thesis presents many of the available solutions, both commercial and freely available. Subsequently, attention is paid to the actual direct communication solution. A solution will be proposed and a~simple application will be implemented demonstrating direct communication between a~Siemens S7-1500 PLC and a Microsoft SQL Server database system. The communication is based on the TDS communication protocol. The implemented application allows direct communication with the database using basic SQL language commands. This solution is competitive with the most currently used indirect communication methods.
