Building new control systems is now based mostly on PLC controllers . We use controllers from
Siemens like S7-300 and S7-1200 series and Mitsubishi FX series . For creating applications for
Siemens PLC controllers we use the newest programming enviroment called TIA Portal.
Of course we also use older programming tools like Step7 MicroWin and Step 7 when it is
neccesary for example to make some modification in older machines .
