Acyklická komunikace po Profinetu mezi měniči Sinamics a PLC řady Simatic S7-1200 / Acyclic Profinet Communication between Sinamics Converters and Simatic S7-1200 PLCs

Dostál, Jiří January 2013 (has links)
This paper deals with acyclic communication of Siemens Simatic S7-1200 PLCs and Sinamics drives on the Profinet industrial bus. Various possibilites of communication of the devices in accordance to the PROFIdrive profile is presented. General Proxy FBs for acyclic read/write of the drive's parameters are implemented. Together with other two FBs, that make use of acyclic communication to read the drive's fault buffer and to adjust an absolute encoder, an application with visualization for a simple positioning and for a demonstration of the Proxy FBs functionality is presented using a demo box.

Návrh a implementace komunikačního serveru / Communication Server Design and Implementation

Sedláček, Robert January 2016 (has links)
In the first part of this work, there is analysis of the industrial proprietary protocol S7 by Siemens. The analysis is performed by Wireshark between the programmable controller S7-1200 and Simatic NET OPC server. This protocol is based on other protocols whose proposals and solutions are completely or at least partially described in this work. On the basis of this information is created a communication library in C ++, which allows the transmission of variables. This library is subsequently used in the implementation of the communication server through which one can easily access variables in the programmable machine with a text protocol.

Laboratorní ukázka řízení asynchronního motoru / Laboratory example of synchronous motor control

Vrtal, Václav January 2010 (has links)
This thesis deals with the speed control three-phase asynchronous motor revolutions by a frequency converter Sinamics G110 by way of the programmable automat SIMATIC S7-224XP. Control of programmable automat is realized the operator panel TP 177 micro. Communication between the PLC and frequency converter is realized by USS protocol on bus RS-485. The main goal was to design and implement software, which would allow operation to choose different variations of speed time histories (sinusoid, saw, jump course, etc.), but also the possibility to control the position. Another goal was to create graphical environment for the operator panel that allows manual control, editing and monitoring of engine speed. The last goal was to evaluate the results and summary of findings during commissioning.

<p>In this thesis, a gas turbine simulator for the Siemens GT10C was developed and implemented. </p><p>It concerns everything from the theory behind the simulator; both the hard- ware and software involved, to how the actual simulator was built using these tools. The theory concerns itself with basic automatic control concepts, as well as basic turbine theory. </p><p>The simulator setup is being discussed concerning both technical and eco- nomic issues.

It concerns everything from the theory behind the simulator; both the hard- ware and software involved, to how the actual simulator was built using these tools. The theory concerns itself with basic automatic control concepts, as well as basic turbine theory. The simulator setup is being discussed concerning both technical and eco- nomic issues.

Přenos a využití procesních dat (PLC) v systému řízení výroby / Transfer and utilization of process data (PLC) in production control system

Kupčík, Michal January 2011 (has links)
This work explains to reader the difficulty of production scheduling and why is much advantageous using proper system for this work. Next he reads about complexity of production management and about necessity of linkage between all levels of company’s IT systems. We are going to use three different approaches for getting Siemens controller’s data out and for two of them we are going to describe general procedure, how we gets a data files, which are openable in classic table processor like MS Excel and which contain user’s choosen variables including their actual values. Finally reader will be familiarized with SimRead program, which serves for reading variable’s values in combination with Simatic standart communication blocks.
