Styrning av Siemens PLC med Android applikation

Sammanfattning: This is a thesis that describes the procedure for setting up the web server on Siemens S7-300 and S7-1200. It also describes how to develop an application on Android to connect to the PLC and then read and send information. It is on the request of ÅF that the Method chapter is written as a step – by – step manual for easy repeat of the project and to get similar results. To communicate with the PLC, all steps in the report have been made and the mobile phone has been able to start and stop a motor while reading its values. The application is intended to be sold by ÅF as a service to their customers. A fixed price could not be decided because the PLC program is varying in size. Each application must be tailored to a PLC program. The integrated web server was chosen because it was the cheapest option for establishing the communication between the Smartphone and the CPU. The report describes alternative methods to the web server.
