Mechatronics Engineering has become an internationally recognized discipline with degree programmes offered in majority of the universities all around the world. Integrating mechanical, instrumentation, and programmable automation controller (PAC) for developing technical skills and expertise in system level integration to attain manufacturing and controller programming superiority has become the basic requirement for Mechatronics Laboratory. Divulging the graduates to servo control concept down the line to the programmable automation controller helps to gain the practical knowledge in the field of I/O interfacing, closed loop control, remote monitoring, and PLC motion control programming. Hence in this paper, a 3-axis servo control system with HMI work bench case study has been presented to enable the graduates to learn multi-disciplinary concepts in the field of material handling and precise position synchronous control of multi-axis rotating system. With this work bench, applications of servo control such as electronic gearing (positioning), pick and place (material handling), and profiling (welding, machining) can be exposed to mechatronics graduates. Graduates with fundamental programming skills and apparently no-practical experience with mechatronics systems can quickly learn how to incorporate control architectures with this work bench and prepare them to compete in Industry 4.0 environment.

A programmable logic controller (PLC) is the core of any industrial automation. For many years, PLC is used mostly to solve logical control tasks. Increasing processor performance and memory capacity, PLCs have the ability to handle a number of different and more complex tasks that are no longer just logical type. This kind of controller is the programmable automation controller (PAC). In industrial control systems are present different kinds of architecture and concepts for integration in enterprise information systems. Edge computing architecture is one of them. In this paper is described a comparison of performance some of the micro/mini PLC/PAC in order to find how of micro/mini PLC/PAC can fit in the Edge Computing Architecture.

WEAVE is a wide-field spectroscopy facility for WHT which includes a multi-object dual-beam spectrograph which will operate in the visible wavelength range. The blue beam will cover the range 360-600 nm and the red arm will cover the 580-960 nm range. In these ranges the spectrograph will offer a mid-resolution (similar to 5000), while in three narrower wavelength intervals, two for the blue arm and one for the red one, the instrument will provide a high (similar to 20000) spectrograph resolution. The spectrograph is currently entering the assembly and integration phase and the first light is foreseen in 2019. The entire WEAVE project is managed by an international consortium led by the University of Oxford. The spectrograph is controlled by a coordination process, the so called High-Level Server, which is part of the Observatory Control System (OCS) software suite, and is the single point of access to the embedded control system, the so called Low-Level Control Software, which is based on PAC technology. This paper describes the design of the embedded software for the control of the spectrograph mechanisms. We first describe the interface between high and low level software, then we present the PAC architecture and discuss the low-level state machine. Finally, we provide details on the principal program routines and describe the engineering interface.

Power stations of transmission system in the Czech Republic are currently undergoing a major modernization. Part of this process includes the changing of lighting systems and their controlling. These steps should lead not only to reducing energy consumption of the lighting systems, but also to increasing safety in terms of security and employees working inside outdoor power stations. An indispensable part of the modernization of the lighting systems in the power stations is also reducing the maintenance demand, due to the increasing cost of labor and unmanned operation of the power stations. The reconstruction of the power stations of Czech transmission system and the construction of new power stations involves installing new outdoor lighting systems, which must apply to current norms and standards, particularly CSN EN 12464-2 and CEPS (Czech Transmission System Company) standards, which are based on European ones. An operation of the lighting systems in the power stations is going to be monitored by control system PAC (programmable automation controller), which allows, among other things, to diagnose various types of luminaires and lighting systems. The aim of the usage of the PAC control system is both reliable operation control of outdoor lighting systems and monitoring and diagnosing of them by remote monitoring from a central control room.

A key input parameter to governor feedback control and stability protection of generators in the angle of the induced voltage internal to the generator. Current practice is to estimate this value using measurements from the terminals of the generator and mathematical models. This project aims to develop a system that would directly measure the internal angle of the generator using a rotary encoder on the shaft of the machine. This document describes the theory and experimental setup of this proposed system and outlines the test procedure of experimentation.
