Program pro testování přípravku PPZ082

Abstract

The aim of this thesis is to create an application that will help to facilitate preparations for setting the control pressure sensors in the company Elgas Ltd. The theoretical part is an approximation Modbus protocol, which communicates with the processor measurement products. It describes the communication protocol and functions, method of transmission of messages and how to handle error conditions. Further, the introduction to this section with PPZ082 and functions necessary for processing requests. And at the end of the circuit is discussed and the FTDI library that mediates communication of USB interface. The practical part consists of a description of the implementation of applications, design and structure analysis of each method with examples of code.
