Orginal scientific paper Nowadays, with the development of information technology, real-time and reliable devices have been developed for users and system control. Commonly used ones are programmable logic controller and operator panels. Programming of these devices, learning the communication with the controller and the hardware installations have gained great importance especially for technic...

This paper presents a software module made by means of programmable logic controller and an HMI (Human Machine Interface), designed to control the movement electric wheelchair. By developing this module, major advantage is offered people with disabilities, who have difficulties. implementing command on wheelchair, can move independently using machine that be controlled from touch screen. In dir...

Programmable logic controller (PLC) can be programmed for various purposes, one of which is to design a fire extinguishing system, by assembling several components PLC, solenoid, springkle, powersupply ,adapter ,smokedetector, heatdetector, pilotlamp, pushbutton, relay, selector switch. the program settings detect smoke and high temperatures that occur in event fire. if sensor detects temperatu...

This paper investigates a modified modeling of networked control systems (NCSs) with programmable logic controller (PLC). First, the controller-to-actuator and sensor-to-controller network-induced delays are investigated by tactics based on hierarchical coloured petri net (HCPN) in structure-conserving way. Comparing recent result, signal transmission delay is set random interval instead fixed ...
